Abstract: An ultrasound diagnostic apparatus performs transmission and reception of ultrasonic waves for forming focal points used to set sound velocities at predetermined timing such that sound velocities having been set for all of respective segment regions established by diving a subject are all reset every predetermined number of frames. Owing to this configuration, it becomes possible for the ultrasound diagnostic apparatus to suitably reset sound velocities of ultrasonic waves in the subject and also reduce the amount of calculation for resetting sound velocities.

Abstract: When tissue elasticity of a subject is measured, an ultrasound diagnostic apparatus sets a sound velocity for each of segment regions established by dividing the subject, processes reception signals output by a piezoelectric element array based on the set sound velocities, and performs tissue elasticity measurement based on the reception signals processed based on the set sound velocities. Owing to this configuration, when tissue elasticity of a subject is measured, the ultrasound diagnostic apparatus prevents the accuracy of tissue elasticity measurement from deteriorating due to image distortions.

Abstract: Ultrasonic transmission and reception for sound speed setting is performed in response to an instruction to freeze, an instruction on an observation target range, an instruction to change image quality and an instruction to change an image mode, a reception signal obtained by the ultrasonic transmission and reception for sound speed setting is used to set the sound speed in a subject, and a reception signal obtained during ultrasonic transmission and reception is processed based on the set sound speed to produce an ultrasound image. Such method makes it possible to produce a high-quality ultrasound image subjected to delay correction appropriate to various operations on an ultrasound diagnostic apparatus, such as freezing and change in image quality.

Abstract: In an ultrasound diagnostic apparatus, when a compound image is produced, delay correction is performed on all of ultrasound images (sub frames) to be combined based on sound velocities set for respective segment regions obtained by dividing the subject. Owing to this configuration, the ultrasound diagnostic apparatus can produce a high quality compound image by spatial compounding or frequency compounding without being affected by distortion in images.
