Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a graphic user interface for defining and operating processes performed on a magnetic resonance imaging apparatus.

[0002]

2. Description of the Related Art Magnetic resonance imaging apparatuses (hereinafter referred to as "M")
The "RI device" measures the density distribution and relaxation time distribution of nuclear spins at a desired inspection site of a subject by using an NMR (nuclear magnetic resonance) phenomenon, and obtains a desired cross section of the subject from the measurement results. Is an image display device.

A technique of a graphic user interface (hereinafter, referred to as “GUI”) for defining and operating processes such as imaging, image processing, and printing performed on such an MRI apparatus is called a task card. 2. Description of the Related Art There is known a technique in which individual processing is defined in advance for a display object imitating a card, and the operation of the processing defined on the task card and the processing result are displayed.

In this technique, as shown in FIG.
In a window on a display device provided in the I device, a plurality of task cards having tabs provided at positions that do not overlap each other in the vertical direction are displayed with portions other than the tabs overlapped.
Then, the task card having the tab selected by the user is moved to the foreground and displayed, and in the task card, an operation of a process defined in the task card is accepted,
It displays an image of the processing result.

Here, the processing corresponding to each task card can be defined in association with the input / output relationship. With this input / output relationship, for example, an image of a processing result (output) corresponding to a certain task card can be set as a processing target (input) of processing corresponding to another task card.

As described above, since the output relationship can be provided between the processes, the process corresponding to each task card has a restriction on the order of processes to be executed. Therefore, conventionally, a processing order that satisfies the restriction on the processing order of this processing is defined in advance, and the tab positions of the task cards corresponding to the respective processings are determined according to the processing order. That is, the task card is displayed in the window so that the tab of the task card of the process to be executed earlier is positioned higher. In addition, each tab displays a name that can identify the process corresponding to the task card.

[0007]

However, when the number of processes to be performed on the MRI apparatus becomes large and complicated, the relationship between the processes becomes complicated. It is difficult to understand the relationship. In particular, in an MRI apparatus, there are various types of processing even in the imaging processing alone, and more complicated imaging is often performed using the resulting image. In addition, since a large number of images resulting from the imaging process and processes using the image also occur, in the technology using the task card, the definition of the process for the task card and the relationship between the process results of the processes corresponding to each task card are defined. It becomes difficult to grasp. Further, for example, when the user wants to execute only the processing necessary for obtaining the processing result of a certain processing regardless of the tab order, that is, the processing order defined in advance, which task card corresponds to which task card It is difficult to specify whether the process is a process to be executed.

Accordingly, an object of the present invention is to provide an MRI apparatus that allows a user to more intuitively grasp the input / output relationship of processing performed on the MRI apparatus and the order of the input / output. Accordingly, it is an object of the present invention to provide an MRI apparatus capable of performing various kinds of imaging with good procedure and using the obtained result image in diagnosis effectively.

[0009]

In order to achieve the above object,
The present invention provides, in an MRI apparatus, a display apparatus and a plurality of tasks that are processes performed in the MRI apparatus that can have an input / output relationship with each other.
