s101, determining an imaging area.
A user of the functional ultrasound imaging device may hold the ultrasound probe to determine the imaging region, and thus the functional ultrasound imaging device may acquire the imaging region. For example, the imaging region may include blood vessels of a mouse brain, the blood vessels may be micro-blood vessels, or the imaging region may include a mouse heart.
In the present embodiment, the size of the imaging area is not limited, and may be different according to the actual application. For example, where the imaging region includes a blood vessel of a mouse brain, the imaging region may be smaller in size.
S102, determining a plurality of sending and receiving group pairs in a plurality of sparse arrays, wherein each sending and receiving group pair comprises a sending sparse array and a receiving sparse array. The plurality of sparse arrays are obtained by randomly dividing the ultrasonic transduction array element arrays, and the transmission sparse arrays and/or the reception sparse arrays in different transmission and reception group pairs are different.
The array elements in the ultrasonic probe may be referred to as an ultrasonic transducer array. The number of array elements in the ultrasonic probe and the arrangement mode of the ultrasonic transduction array elements are not limited in this embodiment.
Fig. 2 is a schematic diagram of an ultrasonic transducer array according to an embodiment of the present application. As shown in fig. 2, the number of array elements in the ultrasound probe is 14×12. The ultrasonic transduction array element array comprises 4 areas from top to bottom, and adjacent areas are separated. Each region includes 14 x 3 array elements.
Fig. 3 is another schematic diagram of an ultrasonic transducer array according to an embodiment of the present application. As shown in fig. 3, the number of array elements in the ultrasound probe is 12×12. The ultrasonic transduction array element array comprises 16 areas, and the adjacent areas are separated. Each region includes 3*3 array elements.
Fig. 4 is a schematic diagram of an ultrasound transducer array according to an embodiment of the present application. As shown in fig. 4, the number of array elements in the ultrasound probe is 14×14. The ultrasonic transduction array element array comprises 1 area, wherein the area comprises 14 x 14 array elements.
It should be noted that fig. 2 to fig. 4 are only examples, and are not limited to the number of array elements and the arrangement of the array of ultrasonic transducer elements.
In this embodiment, the array of ultrasonic transducer elements may be randomly divided to obtain a plurality of sparse arrays, so as to form a sparse array set. By sparse array, it is meant that the number of 0 elements with a value of 0 is much greater than the number of non-0 elements in the matrix, and the distribution of non-0 elements is irregular. In this embodiment, the element other than 0 may be understood as an element that needs to transmit and receive ultrasonic waves, and the element 0 is an element that does not need to transmit and receive ultrasonic waves.
Note that, the method of randomly dividing the sparse array is not limited in this embodiment.
An exemplary description is provided below in connection with fig. 4 and 5. Fig. 5 is a schematic illustration of the sparse array of fig. 4. As shown in fig. 5, the array of ultrasonic transducer elements may be divided into 4 regions, each region comprising 7*7 elements. The array elements of the sparse array in each region are represented by black, and each sparse array comprises 9 array elements. In fig. 5, 4 sparse arrays are included, identified as A1, A2, A3, A4. It will be appreciated that when transmitting and receiving ultrasound through array elements in a sparse array, each array element corresponds to a channel, the number of channels may be greater than or equal to 9, and the minimum may be 9.
A plurality of transmit receive set pairs may be determined among the plurality of sparse arrays, each transmit receive set pair comprising 2 sparse arrays. The sparse array for transmitting ultrasonic waves is referred to as a transmit sparse array, and the sparse array for receiving ultrasonic waves is referred to as a receive sparse array.
Optionally, in order to make the array elements in the ultrasonic transduction array element arrays of the multiple transmitting and receiving sets form uniform coverage as many as possible, the functional ultrasonic imaging effect is improved, and the transmitting sparse arrays and/or the receiving sparse arrays in different transmitting and receiving sets are different.
For example, as shown in fig. 5, 3 transmission-reception group pairs may be determined among 4 sparse arrays (A1, A2, A3, A4). The transmission-reception group pair 1 includes a transmission sparse array A1 and a reception sparse array A2. The transmission-reception group pair 2 includes a transmission sparse array A1 and a reception sparse array A3. The transmission-reception group pair 3 includes a transmission sparse array A4 and a reception sparse array A1. Wherein, the transmitting and receiving group pair 1 and the transmitting and receiving group pair 2 have the same transmitting sparse array A1.
The ultrasonic transducer array is divided randomly to obtain a plurality of sparse arrays, a plurality of transmitting and receiving group pairs are determined in the plurality of sparse arrays, so that plane waves can be prevented from being transmitted in the process of functional ultrasonic imaging, the transmitting sparse arrays and the receiving sparse arrays in the transmitting and receiving group pairs are used, the number of array elements for transmitting and receiving ultrasonic waves each time is reduced, namely the number of channels is reduced, and therefore the complexity and the cost of equipment of the functional ultrasonic imaging equipment can be reduced. In addition, as a plurality of transmitting and receiving group pairs are determined, through the transmission and the reception for a plurality of times, the array elements for transmitting the ultrasonic waves and the array elements for receiving the ultrasonic waves are covered on the ultrasonic transduction array element array as far as possible, and a larger imaging range is obtained without losing the functional ultrasonic imaging resolution.
Optionally, in an implementation manner, the ultrasonic transducer array may be randomly divided in advance according to the maximum number of channels to obtain a plurality of sparse arrays, and the plurality of sparse arrays are stored. The sparse array includes fewer than or equal to the maximum number of channels.
In the implementation mode, the plurality of sparse arrays are divided and stored in advance, and the implementation mode is simple.
Optionally, in another implementation, before determining the plurality of transmitting-receiving group pairs in the plurality of sparse arrays, the method may further include:
and randomly dividing the ultrasonic transduction array element array according to the imaging area and the maximum number of channels to obtain a plurality of sparse arrays. Wherein the sparse array comprises fewer than or equal to the maximum number of channels.
In the implementation mode, a plurality of sparse arrays can be obtained through dividing according to the imaging area and the maximum number of channels, the implementation mode is more flexible, and the obtained sparse arrays are more reasonable. For example, if the size of the imaging area is smaller, the array elements in the sparse array can be located at the center of the ultrasonic transduction array element as much as possible, so that the accuracy and the effectiveness of ultrasonic transmission and reception are improved.
S103, for each transmitting and receiving group pair, controlling the transmitting sparse array in the transmitting and receiving group pair to transmit ultrasonic signals to the imaging area according to a plurality of preset angles, and receiving echo signals through the receiving sparse array in the transmitting and receiving group pair.
For example. It is assumed that the plurality of preset angles includes-6 °, -3 °, 0 °, 3 ° and 6 °. The number of the sending and receiving group pairs is 2, and the sending and receiving group pairs are identified as sending and receiving group pair 1 and sending and receiving group pair 2. Then, for the transmission-reception group pair 1, the transmission sparse array in the transmission-reception group pair 1 is controlled to sequentially transmit ultrasonic signals to the imaging region at-6 °, -3 °, 0 °, 3 ° and 6 °, and echo signals are sequentially received at-6 °, -3 °, 0 °, 3 ° and 6 ° by the reception sparse array in the transmission-reception group pair 1. Similarly, for the transmitting-receiving group pair 2, the transmitting sparse array in the transmitting-receiving group pair 2 is controlled to sequentially transmit ultrasonic signals to the imaging region at-6 °, -3 °, 0 °, 3 ° and 6 °, and echo signals are sequentially received at-6 °, -3 °, 0 °, 3 ° and 6 ° by the receiving sparse array in the transmitting-receiving group pair 2.
Through confirming a plurality of sending and receiving group pairs, through setting up a plurality of preset angles, different sending and receiving group pairs of different angles can be accomplished and ultrasonic signals are sent and received to the effect of plane wave can be sent in a simulated manner, the resolution ratio of functional ultrasonic imaging has been guaranteed. Moreover, since the direct transmission of plane waves is avoided, a larger imaging range is obtained without losing functional ultrasound imaging resolution.
S104, generating an ultrasonic synthetic image according to the echo signals respectively received by the multiple sending and receiving groups under multiple preset angles.
Optionally, in S104, generating an ultrasound synthetic map according to the plurality of transmitting and receiving sets for echo signals received at a plurality of preset angles respectively may include:
and for each preset angle, performing global channel processing on echo signals respectively received under the preset angles according to a plurality of sending and receiving groups to generate a first single-angle synthetic image.
And generating an ultrasonic synthetic image according to the first single-angle synthetic images respectively corresponding to the plurality of preset angles.
As illustrated in connection with fig. 5.
Assume that the transmission/reception group pair (transmission sparse array, reception sparse array) is 4 pairs, specifically: transmitting and receiving group pair 1 (A1, A2), transmitting and receiving group pair 2 (A1, A3), transmitting and receiving group pair 3 (A2, A3), and transmitting and receiving group pair 4 (A4, A1). The plurality of preset angles includes-6 °, -3 °, 0 °, 3 ° and 6 °.
And for a preset angle of minus 6 degrees, controlling the transmission sparse arrays of the transmission and reception group pairs 1 to 4 to transmit ultrasonic waves according to minus 6 degrees, correspondingly, receiving echo signals by the reception sparse arrays of the transmission and reception group pairs 1 to 4, and carrying out global channel processing on the echo signals respectively received by the transmission and reception group pairs 1 to 4 at minus 6 degrees to generate a first single-angle synthetic graph which is shown as a graph B (-6 degrees). Because the number of the array elements in the transmission sparse array and the receiving sparse array in the transmission and receiving group pair 1-4 is small, through global channel processing, the array elements in the ultrasonic transduction array element array of the transmission and receiving group pair 1-4 can form global coverage, so that the effect of transmitting plane waves can be simulated, and the resolution of functional ultrasonic imaging is ensured.
