First Claim
1. An ultrasonic diagnostic apparatus comprising:
- a processor configured togenerate, based on a reflection wave signal of an ultrasonic wave that is transmitted into a subject, strain information indicating a spatial distribution of a strain of a tissue that is pressured and released in the subject for each of a plurality of time phases;
calculate an indicator indicating pressure and release to the tissue at generation of the strain information, based on the reflection wave signal;
control to store a plurality of images in a memory, each of the plurality of images being generated based on the spatial distribution indicated by the strain information and corresponding to each of the plurality of time phases;
rank the plurality of time phases based on magnitude of the indicator;
extract first time phases among the plurality of time phases, based on the ranking of the plurality of time phases; and
control to display, in a display order, at least two of the plurality of images stored in the memory corresponding to the extracted first time phases,wherein the display order of the at least two images is based on a result of the ranking of the plurality of time phases such that an image corresponding to a second rank in the ranking is displayed immediately after an image corresponding to a first rank in the ranking is displayed.

Abstract
An ultrasonic diagnostic apparatus according to an embodiment includes a signal processing unit, an indicator calculating unit, a storage unit and a controller. The signal processing unit generates, based on a reflection wave signal of an ultrasonic wave that is transmitted into a subject, strain information about a strain of a tissue that is pressured and released in the subject in chronological order. The indicator calculating unit calculates an indicator of a state of pressure and release to the tissue at generation of the strain information. The storage unit stores a time phase at generation of the strain information and the indicator at generation of the strain information in an associated manner. The controller extracts a candidate time phase being a time phase of a candidate based on the indicator associated with each of the time phase.
