Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The medical examination image method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 acquires a viewing instruction for a medical examination image of a patient; acquiring image information of each medical examination image in the associated examination sequence from the server 104 according to the patient identifier carried in the viewing instruction; the terminal 102 adds the downloading task of each medical examination image into the sequence queue according to the image information of each medical examination image, and downloads each medical examination image from the server 104 through the sequence downloading thread according to the downloading sequence in the sequence queue; when images in the medical examination images are triggered to be downloaded preferentially, determining a first preferentially downloaded image in the medical examination images; and adding the downloading task of the first priority downloading image into the head of the priority queue, and downloading the first priority downloading image from the server 104 through the priority downloading thread. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster composed of a plurality of servers, and may be a node in a block chain.
In one embodiment, as shown in fig. 2, a medical examination image method is provided, which is exemplified by the application of the method to the terminal in fig. 1, and comprises the following steps:
in step S220, a viewing instruction for a medical examination image of a patient is acquired.
The medical examination image is an image of an internal tissue obtained by a medical imaging technique in a non-invasive manner on a human body or a certain part of the human body, and the medical imaging technique includes: CT, B-mode ultrasonography, X-ray film, nuclear magnetic resonance, cardiovascular radiography, doppler color ultrasonography, etc. The viewing instruction is a viewing instruction obtained by the terminal based on the triggering operation of the doctor when the doctor views the medical examination image of the patient through the terminal, such as: the doctor can trigger the viewing instruction by clicking the viewing control of the medical examination image of the patient displayed by the terminal. Such as: and a doctor clicks a picture adjusting control on the client based on the client corresponding to the medical image cloud system on the terminal, so that a viewing instruction of the terminal is triggered.
Step S240, acquiring image information of each medical examination image in the associated examination sequence from the server according to the patient identifier carried in the viewing instruction.
The patient identifier is a mark for marking a patient, and may be a patient number, and one patient number corresponds to one unique patient. A patient may have one or two examination items, and an examination item may have one or two sequences formed by classifying the patient according to each medical examination image in the examination item, wherein each sequence comprises one or more than two medical examination images. Each medical examination image and corresponding image information is associated with a patient identification. The image information is the relevant information of the medical examination image, such as: image number, image thickness, pixel value, etc.
In one scenario, patient a performs a CT examination and the CT device generates medical examination images. These images may be categorized into n examination sequences, each containing a plurality of medical examination images. Medical examination images of a plurality of examination sequences are generated based on one examination item, and each medical examination image in each examination sequence is associated with a patient identifier of a patient a. As shown in fig. 3, the server manages the medical examination images through a three-layer structure of "examination-examination sequence-images", and it is emphasized that, in order to further ensure the privacy and security of the patient information and medical examination images of the patient, the server managing the patient information and medical examination images of the patient may be a node of a block chain, and the medical examination images are stored in the block chain. The examination information is common information of all images of an examination, such as an examination number, examination time, patient name and the like, the examination number can be used for identifying an examination, common information of all images in each sequence below the examination is used as examination sequence information corresponding to each sequence, the examination sequence information can be serial number, sequence description, equipment type and the like, each medical examination image below each sequence also has image information corresponding to each medical examination image, and the image information can be image number, image thickness, pixel value and the like. When a doctor needs to check medical examination images of the CT examination of the patient A, the doctor clicks a CT examination check control of the patient A based on a client corresponding to a medical image cloud system on a terminal, the CT examination has a corresponding patient identifier, and image information of the medical examination images under examination sequences related to the patient identifier can be obtained from a server correspondingly.
Step S260, according to the image information of each medical examination image, the downloading task of each medical examination image is added into the sequence queue, and each medical examination image is downloaded from the server through the sequence downloading thread according to the downloading sequence in the sequence queue.
Wherein the downloading task is a task of downloading medical examination images. The sequential queue is a queue for storing all medical examination image tasks to be downloaded according to the sequential storage structure. The sequential download thread is a download thread for downloading medical examination image tasks stored in the sequential queue. And sequentially downloading the medical examination images to the slave server by the sequential downloading thread according to the head of the queue in the sequential queue, and deleting the downloaded tasks from the queue. In practical use, the number (N) of the downloading threads of the sequence queue is the number (P) of the logic cores of the CPU minus the number (M) of the downloading threads of the priority queue, the number (N) of the downloading threads of the sequence queue is greater than 1, the number (M) of the downloading threads of the priority queue is greater than or equal to 2, and the number of the downloading threads of the sequence queue is flexibly set according to the terminal configuration by taking the number (N) of the downloading threads of the sequence queue as a principle.
In step S280, when an image in each medical examination image is triggered to be downloaded preferentially, a first preferentially downloaded image in each medical examination image is determined.
Wherein, the first priority download image is a medical examination image which needs to be downloaded in advance in the medical examination images which are not downloaded in the sequence queue. The first priority download image may be one medical examination image or may be two or more medical examination images.
And step S300, adding the downloading task of the first priority downloading image into the head of the priority queue, and downloading the first priority downloading image from the server through the priority downloading thread.
Wherein, the downloading task of the first priority downloading image is the downloading task of the medical examination image needing to be downloaded in advance. The priority queue is a queue for storing a download task of a first priority download image which needs to be downloaded preferentially. The priority downloading thread is a downloading thread for downloading a downloading task of the medical examination images stored in the priority queue. When more than two first priority downloading images are available, the downloading tasks of the first priority downloading images can be arranged from the head of the priority queue to the tail of the priority queue according to the downloading priority, and the first priority downloading images are downloaded by the priority downloading thread according to the sequence in the priority queue.
In the medical examination image downloading method, when a viewing instruction of a medical examination image of a patient is triggered, the terminal acquires image information of each medical examination image in an associated examination sequence from the server according to a patient identifier carried in the viewing instruction; according to the image information of each medical examination image, adding the downloading task of each medical examination image into a sequence queue, and downloading each medical examination image from a server through a sequence downloading thread according to the downloading sequence in the sequence queue; when one or more medical examination images need to be viewed preferentially, a preferential download instruction can be triggered to determine a first preferential download image in each medical examination image; and adding the downloading task of the first priority downloading image into the head of the priority queue, and downloading one or more medical examination images needing to be viewed preferentially from the server through the priority downloading thread. The user can quickly read the image needing to be read preferentially without waiting for queuing for downloading, and the efficiency of reading the medical examination image by the user is improved.
In one embodiment, the downloading task of each medical examination image is added into the sequence queue according to the image information of each medical examination image, and each medical examination image is downloaded from the server through the sequence downloading thread according to the downloading sequence in the sequence queue, and the method comprises the following steps:
performing image type analysis according to the image information of each medical examination image, and determining whether each medical examination image is a thumbnail corresponding to the examination sequence to which the medical examination image belongs; adding the downloading task of the medical examination images which are the thumbnails corresponding to the belonged examination sequence to the head of the sequence queue, and adding the downloading task of the medical examination images which are not the thumbnails corresponding to the belonged examination sequence to the tail of the sequence queue; and downloading the medical examination images from the server through the sequential downloading thread according to the downloading sequence in the sequential queue.
The thumbnail is a representative of the examination sequence, one thumbnail can be used for representing the examination sequence, when a doctor views medical examination images of a patient, the thumbnail of each examination sequence needs to be displayed first, so that the doctor can conveniently see the sequencing of each examination sequence in a terminal interface, and the medical examination images which the doctor wants to see are quickly found. The thumbnails are preferentially downloaded and displayed, the thumbnails are used as an operation entrance, and a doctor can switch the currently displayed examination sequence by clicking a certain thumbnail. Thus, the thumbnails for each inspection sequence need to be downloaded first. The image type analysis is carried out according to the image information of each medical examination image, whether each medical examination image is a thumbnail corresponding to the belonging examination sequence is determined, and whether each medical examination image is the thumbnail is judged, wherein the image number can be the image number in the image information of the medical examination image (the image number is numbered according to the sequence of the medical examination images in the examination sequence, for example, the serial number of one examination sequence is D, and the image number of the first image in the examination sequence is D-1), and whether the medical examination image is the first image of the examination sequence, if the medical examination image is the first image, the first image is the thumbnail, and if the medical examination image is not the first image, the first image is not the thumbnail. The download task of the medical examination images which are the thumbnails corresponding to the belonging examination sequence is added to the head of the sequence queue, the download task of the medical examination images which are not the thumbnails corresponding to the belonging examination sequence is added to the tail of the sequence queue, and the formed sequence queue is shown in fig. 4.
In an embodiment, referring to fig. 5, after the step of adding the downloading task of the first priority downloaded image to the head of the priority queue and downloading the first priority downloaded image from the server through the priority downloading thread, the method further includes steps S420 to S460:
step S420, determining the position of the first priority downloaded image in the belonging check sequence according to the image information of the first priority downloaded image.
The image information of the first priority downloading image comprises the image number of the first priority downloading image, and the image number can determine the position of the first priority downloading image in the checking sequence.
Step S440, according to the position of the first priority download image in the checking sequence, determining a second priority download image from the checking sequence.
According to the position of the first priority download image in the belonging inspection sequence, the image information of the medical inspection images arranged in front of and behind the first priority download image in the belonging inspection sequence and the number of the medical inspection images arranged in front of and behind the first priority download image can be determined, a preset number of medical inspection images arranged in front of and behind the first priority download image can be taken as a second priority download image, the preset number can be 2, 3, 4 or the like, and the preset number can be set according to actual use requirements.
Step S460, adding the download task of the second priority downloaded image into the priority queue, and downloading the second priority downloaded image from the server preferentially through the priority download thread.
When the download task of the second priority download image is added to the priority queue, the download task of the second priority download image is arranged behind the first priority download image, as shown in fig. 6. In one scene, the focus is three-dimensional, one focus can be positioned on several adjacent medical examination images, so the observation habit of a doctor is to look up the whole view of the focus by turning up and down after finding the focus, the first priority downloaded image and m medical examination images before and after the first priority downloaded image are put into a priority queue to wait for downloading, the examination sequence or the medical examination image which the doctor is interested in can be judged, the examination sequence or the medical examination image which the doctor is interested in is controlled to be downloaded with high priority by utilizing the priority queue, the sequence queue and the multithreading technology, and other medical examination images are downloaded according to low priority in sequence, so that the doctor can quickly see the medical examination image of the interested part.
In one embodiment, the downloading task of the first priority downloading image is added to the head of the priority queue, and the first priority downloading image is downloaded from the server through the priority downloading thread, and the downloading task comprises the following steps:
judging whether the downloading task of the first priority downloading image is in the priority queue or not according to the image information of the first priority downloading image; when the downloading task of the first priority downloading image is in the priority queue, the downloading task of the first priority downloading image is placed at the head of the priority queue, and the first priority downloading image is downloaded from the server through the priority downloading thread; and when the downloading task of the first priority downloading image is not in the priority queue, reconstructing the priority queue, putting the downloading task of the first priority downloading image to the head of the priority queue, and downloading the first priority downloading image from the server through the priority downloading thread.
Wherein, the number of downloading threads (M) of the priority queue is set to be 2 or more than 2. When the download task of the first priority download image is already in the priority queue, it may be a case where the first priority download image is already defined as a case where the second priority download image is added to the priority queue before the first priority download image is defined as the first priority download image, but the download task has not yet been executed. The downloading task of the first priority downloading image is not in the priority queue, and the downloading task of the first priority downloading image is not added into the priority queue before the downloading task of the first priority downloading image. The reconstruction priority queue is used for starting a downloading task of a first priority downloading image in the priority queue storage. The downloading order of the first priority download image stored in the priority queue is changed in real time, for example, when observing lung images, the user may want to first see the enhancement sequence and then see the flat scan sequence. Therefore, when the doctor looks at the third image of the enhanced sequence with priority, the priority of the sequence is also high, the downloading task of the third image of the enhanced sequence is put at the head of the priority queue, and even if the task which is not downloaded is still in the priority queue, the downloading task of the third image of the enhanced sequence is still put at the head of the priority queue. The first priority download image arranged at the head of the priority queue can be changed in real time according to the checking condition of a doctor. After the first priority downloaded image is added to the head of the priority queue and is waiting for downloading, the downloading task corresponding to the first priority downloaded image queued in the sequence queue for downloading can be deleted.
In one embodiment, when an image in each medical examination image is triggered to be downloaded preferentially, determining a first preferentially downloaded image in each medical examination image comprises:
when detecting that the inspection sequence which is not downloaded is selected, triggering preferential downloading; determining the selected checking sequence according to the priority downloading; taking the medical examination images which are not downloaded in the selected examination sequence as first priority download images;
or, when the medical examination images which are not downloaded are detected to be browsed, the preferential downloading is triggered; determining the browsed medical examination image according to the priority downloading; a first priority download image is determined based on image information of the viewed medical examination image.
Wherein, the check sequence selected without downloading is detected, such as: for example, the medical examination images of the enhanced sequence are downloaded first, and then the medical examination images of the flat-scan sequence are downloaded, while the doctor needs to watch the medical examination images of the flat-scan sequence first, and then triggers to download the medical examination images of the flat-scan sequence preferentially by clicking the thumbnails of the flat-scan sequence, and the medical examination images which are not downloaded in the flat-scan sequence are all used as the first priority download images. Browsing of medical examination images not downloaded is detected, such as: for example, lung images, the downloading task in the sequence queue is to download the medical examination images of the enhanced sequence first and then download the medical examination images of the flat-scan sequence, and if the doctor needs to see the third medical examination image in the flat-scan sequence first, the browsing interface is turned to the interface of the third medical examination image in the flat-scan sequence, and the third medical examination image is displayed after the downloading is completed, and then the third medical examination image is used as the first priority downloading image.
In one embodiment, determining a first priority download image based on image information of a viewed medical examination image comprises: detecting whether the images currently downloaded by the sequential downloading thread and the priority downloading thread comprise the browsed medical examination images or not according to the image information of the browsed medical examination images; when the browsed medical examination image is not included, taking the browsed medical examination image as a first priority download image; when the browsed medical examination image is included, the browsed medical examination image is not downloaded as the first priority.
When the browsed medical examination image is downloaded in the sequential downloading thread or the priority downloading thread, the priority downloading is not needed to be carried out as the first priority downloading image, the conflict problem caused by delay of the sequential queue and the priority queue can be solved, and the waste of network resources is reduced.
In one embodiment, the medical examination image downloading method further comprises: when the downloading of the currently downloaded image of the sequential downloading thread or the priority downloading thread is finished, detecting whether the image exists in a local disk or not; when the image exists in the local disk, discarding the image; and when the image does not exist in the local disk, storing the image in the local disk.
The local disk is a disk used by the client for storing the medical examination images which are downloaded. The currently downloaded image is the medical examination image currently downloaded in the sequential downloading thread or the priority downloading thread. And after downloading, detecting, namely judging whether the file on the disk exists or not when the downloading is finished, and if so, discarding the currently downloaded image. This avoids frequent execution of multi-threaded lock operations without affecting download speed.
It should be understood that although the steps in the flowcharts of fig. 2 and 5 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2 and 5 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the steps or stages is not necessarily sequential, but may be performed alternately or alternately with other steps or at least some of the other steps or stages.
