Problems solved by technology

However, since the ultrasonic echoes reflected by the same reflector are received by a plurality of elements, the ultrasonic echo signal reflected by the reflector located at the focal position of the ultrasonic beam transmitted from the transmitting element and received by the transmitting element is different by The ultrasonic echo signal reflected by the same reflector and received by other elements different from the transmitting element is delayed

[0326] Figure 16 It is a block diagram showing another example of the ultrasonic diagnostic apparatus according to the embodiment of the present invention.

[0327] and figure 1 Compared with the ultrasonic diagnostic apparatus 10 shown, Figure 16 The ultrasonic diagnostic apparatus 10b shown is different in that a sound velocity correction unit 29 is provided, and since the other configurations are the same as those of figure 1 The ultrasonic diagnostic apparatus 10 shown has the same configuration, and thus detailed description thereof will be omitted.

[0328] The sound velocity correction unit 29 is connected to the sound velocity determination unit 23 and the phasing addition unit 38 . In addition, the sound velocity correction unit 29 is connected to the control unit 30 and controlled by the control unit 30 .

[0329] The sound velocity correction unit 29 corrects the sound velocity based on the environmental sound velocity, obtains a sound velocity correction valu...

Abstract

Provided are: an ultrasonic diagnosis device that can form an ultrasonic image at a precision close to that of a multi-focus method, even in the case of a moving image; an ultrasonic image generation method; and a program. In the case of a moving image capture mode, transmission / reception is performed at a single focus, and multi-line processing is performed on the basis of the received element data. Thereafter, image processing is performed and the moving picture of the ultrasonic image is displayed or a sonic velocity value is calculated. Meanwhile, in the case of a static image capture mode, transmission / reception is performed in a multi-focus manner and phasing addition processing or the like is performed on the received element data. Thereafter, image processing is performed, and the static ultrasonic image is displayed or the sonic velocity value is calculated.

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic apparatus, an ultrasonic image generation method, and a program for generating an ultrasonic image for examination or diagnosis of an inspection object by photographing an inspection object such as an internal organ in a living body by transmitting and receiving ultrasonic beams. An ultrasonic diagnostic apparatus, an ultrasonic image generation method, and a program that perform single-focus multi-line processing in a moving image shooting mode and perform multi-focus normal processing in a still image shooting mode. Background technique [0002] Conventionally, in the medical field, ultrasonic examination devices such as ultrasonic imaging diagnostic devices using ultrasonic images have been put into practical use. Generally, such an ultrasonic inspection device has an ultrasonic probe (ultrasonic probe) incorporating a plurality of elements (ultrasonic transducers) and an apparatus main body ...
