Abstract
In an ultrasound diagnosis, the inventor has found a characteristic that coincidence of RF data after matching addition or amplitude image data at the small opening are different between those of an isolated point (minute structure), a continuous surface, and a speckle. On the basis of the characteristic, an ultrasound diagnostic apparatus and method which can distinguish and extract the isolated point, the continuous surface, and the speckle and determine a tissue property are provided.
Claims20
An ultrasound diagnostic apparatus comprising:
- an ultrasound probe including a plurality of ultrasound transducers which transmit ultrasound to a subject and receive the ultrasound reflected by the subject to output an element data;
- an arithmetical operation device which performs matching addition of element data of a plurality of small openings obtained by dividing an opening provided in the ultrasound probe on the basis of the element data output from the ultrasound transducers;
- and
- a determination device which determines a property of a reflector which reflects the ultrasound in the subject on the basis of at least one of RF data obtained by the matching addition of the element data of the small openings and an amplitude image.

An ultrasound diagnostic method comprising:
- an arithmetical operation step for performing matching addition of element data of a plurality of small openings obtained by dividing an opening provided in a ultrasound probe on the basis of element data output from the ultrasound probe, the ultrasound probe including a plurality of ultrasound transducers which transmit ultrasound to a subject and receive the ultrasound reflected by the subject to output the element data;
- and
- a determination step for determining a property of a reflector which reflects the ultrasound in the subject on the basis of at least one of RF data obtained by the matching addition of the element data of the small openings and an amplitude image.
