Patent ID: 8888703

Claim:
An ultrasound imaging apparatus, comprising: an ultrasonic probe and transceiver configured to scan a periodically moving subject with ultrasound waves to acquire a plurality of ultrasound image data representing the subject; a processing circuit configured to set a region of interest in the ultrasound image data acquired in a first time phase, and in time phases after the first time phase, track a position of the region of interest after the first time phase until a second time phase based on ultrasound image data acquired as to generate a first track, wherein the region of interest represents a part of the subject that is in motion during a cardiac cycle, wherein the processing circuit is further configured to receive, from a user interface, manual input of a correction instruction of the position of the region of interest in the second time phase, track the corrected position of the region of interest in and after the second time phase based on the received correction instruction and ultrasound image data acquired in and after the second time phase so as to generate a second track, obtain position information of the region of interest in an interval including the first time phase and the second time phase, the interval including a period before the first time phase and a period after the second time phase, by connecting the first track in a first period after the first time phase and before the second time phase to the second track in a second period in and after the obtained second time phase, and obtain, based on the obtained position information of the region of interest, motion information of the tissue included in the region of interest; and the ultrasound imaging apparatus further includes a display controller circuit configured to cause a display to display the motion information.
