Claim Text:
1. An ultrasonic diagnosis apparatus, comprising: a computer implemented by processing circuitry configured to acquire ultrasonic image data corresponding to a plurality of time phases in a first period, including at least one contraction and one expansion, by ultrasonic scanning throughout the first period for an observation region of an object to be examined, the observation region repeating contracting motion and expanding motion upon application of a dynamic load including repetition of compression and release, generate velocity information concerning a tissue in the observation region in the plurality of time phases in the first period, generate reference information including a graphic chart of velocity of the observation region with time over a plurality of cycles, each of which includes the contracting motion and the expanding motion, determine a second period corresponding to at least one of the contraction motion and the expansion motion, in a period including at least part of the compression and the release, based on the reference information, execute time integration with respect to the velocity information in the second period to generate strain information concerning the tissue corresponding to a second plurality of time phases in the second period, and generate, based on the strain information, a strain image indicating a strain distribution of the observation region; and a display configured to display the strain image in a predetermined form.
