no. 1 Embodiment approach

[0041] First, the configuration of the ultrasonic diagnostic apparatus according to the first embodiment will be described. figure 1 It is a diagram for explaining a configuration example of the ultrasonic diagnostic apparatus according to the first embodiment. like figure 1 As shown, the ultrasonic diagnostic apparatus of the first embodiment includes an ultrasonic probe 1 , a monitor 2 , an input device 3 , and an apparatus main body 10 .

[0042] The ultrasonic probe 1 has a transducer group composed of a plurality of transducers (for example, piezoelectric transducers) arranged in one predetermined direction. These plural transducers generate ultrasonic waves based on a drive signal supplied from a transmission unit 11 included in the device main body 10 described later. In addition, the plurality of vibrators included in the ultrasonic probe 1 receives reflected waves from the subject P and converts them into electrical signals. In addition, the ultrasonic probe 1 has ...

no. 2 Embodiment approach

[0218] In the second embodiment, using Figure 20 ~ Figure 22 A case where the depth of the structure is obtained together with the direction of ultrasonic transmission and reception (deflection angle of ultrasonic waves) and the direction indicating the boundary of the structure to perform displacement-type reception apodization will be described. Figure 20 ~ Figure 22 It is a figure for demonstrating 2nd Embodiment.

[0219] The ultrasonic diagnostic apparatus of the second embodiment and figure 1 The ultrasonic diagnostic apparatus of the first embodiment shown is configured in the same manner. In addition, the receiving unit 12 of the second embodiment and figure 2The reception unit 12 of the first embodiment shown is configured in the same manner. In addition, the control unit 18 of the second embodiment performs control to change the width of the receiving opening according to the position of the receiving focus, as in the first embodiment. That is, the control uni...

no. 3 Embodiment approach

[0239] In the third embodiment, using Figure 24 as well as Figure 25 A method for further improving the image quality of B-mode image data by applying the shift-type reception apodization described in the first embodiment and the second embodiment will be described. Figure 24 as well as Figure 25 It is a figure for demonstrating 3rd Embodiment.

[0240] For example, if referring to Figure 7 The left side of the B-mode image data or Figure 17 For the B-mode image data on the left side, the transceiving beam is deflected at the angle "θ t When turning, the line is drawn obliquely. Therefore, in the third embodiment, the spatial composite method described as the prior art is performed under the control of the control unit 18, thereby solving the above-mentioned problem. Furthermore, in the third embodiment, the control unit 18 In the control of 18, the shift-type receiving apodization is applied to the spatial compounding method of deflecting the transmission beam, so ...

Abstract

An ultrasonic diagnosis apparatus according to an embodiment includes a controller (18), a processor (12), and an image generator (15). The controller (18) selects at least one transducer element in a reception aperture formed of a transducer element group arranged in a predetermined direction, based on at least one of a deflection angle of an ultrasonic wave, an angle between the predetermined direction and a direction indicating a boundary of a structure, and an angle between a direction perpendicular to a normal direction where the predetermined direction intersects with a center of the transducer element group and the direction indicating the boundary. The processor (12) performs processing such that a signal intensity of a reception signal generated in the at least one transducer element is reduced, to output the reception signal of the reception aperture. The image generator (15) generates ultrasonic image data, based on the reception signal.

Description

[0001] Cross References to Related Applications [0002] This application enjoys the benefit of priority of Japanese Patent Application No. 2014-023624 filed on February 10, 2014, and the entire content of the Japanese Patent Application is incorporated in this application. technical field [0003] Embodiments relate to an ultrasonic diagnostic device, an image processing device, and an image processing method. Background technique [0004] Conventionally, various methods have been performed in order to reduce multiple reflections in ultrasonic images (B-mode images), which are obstacles to diagnosis. As an example of this method, there is known a method using spatial compounding in which a plurality of B-mode images in which the deflection angles of ultrasonic transmission and reception are changed are combined (compounded) by averaging. In addition, it is also known to use this method to estimate the degree and position of multiple reflection echo (echo) components from a...
