According to one embodiment, an ultrasonic diagnostic apparatus sets a desired period with reference to a predetermined time phase in each heartbeat of the object, sequentially executes ultrasonic scanning on a plurality of sub-volumes in a period including the diagnosis period to acquire sub-volume data corresponding to a plurality of time phases, controls acquisition timing of the sub-volume data from a time point elapsed from the predetermined time phase by a predetermined period of time while switching the sub-volume, generates composite sub-volume data or a full volume data constituted by a plurality of sub-volume data by performing combining processing of the sub-volume data acquired in the different diagnosis periods, detects at least one of a cyclic change of a heartbeat signal and a change in the number of sub-volume data acquired in the one diagnosis period and performs combining processing of sub-volume data based on a detection result.
Description
technical field [0001] The present invention relates to an ultrasonic diagnostic apparatus, an ultrasonic image processing apparatus, and a medical image diagnostic apparatus for imaging and diagnosing a living body using ultrasonic waves or the like. Background technique [0002] In recent years, image diagnosis using medical image diagnostic apparatuses typified by ultrasonic diagnostic apparatuses, X-ray computed tomography apparatuses, magnetic resonance imaging apparatuses, etc. has played an important role in the clinical field. For example, an ultrasonic diagnostic apparatus emits an ultrasonic pulse generated from a vibrating element installed on an ultrasonic probe into the subject, and uses the vibrating element to receive ultrasonic reflected waves generated due to differences in acoustic impedance of the subject tissue to collect A device for biological information. Ultrasonic diagnostic equipment can display image data in real time with a simple operation such ...
