Ultrasonic diagnostic apparatus and method of controlling the same

摘要

In an ultrasonic diagnostic apparatus including an ultrasonic probe, a scan controller, a storage unit, and an image generation unit, the scan controller receives a trigger signal every heartbeat period, scans each of a predetermined number of blocks of a particular diagnostic region of a body under examination with an ultrasonic beam a plurality of times in response to the trigger signal. The storage unit converts an acquired reflection signal into image data and stores the image data of an amount corresponding to a period in which the body under examination is fully scanned a plurality of times. The image generation unit selects image data from the image data stored in the storage unit for the respective blocks in accordance with the spatial arrangement order without being restricted by the temporal acquisition order, and generates a full image of the body under examination by connecting the selected image data.

主权项

1. An ultrasonic diagnostic apparatus, comprising:
a scan controller configured to scan sub volumes, each sub volume being obtained by dividing a full 3D volume to be imaged, while changing the sub volume every ECG trigger signal so as to acquire a plurality of data sets respectively corresponding to a plurality of heart beats, each data set of the plurality of data sets corresponding to one of the plurality of heart beats and including a plurality of sub data sets, each sub data set within the data set being acquired at a different time phase; and image generation circuitry configured
to select specific sub data sets, including one for each sub volume, for generating an image of the full 3D volume among the acquired plurality of data sets by maximizing a spatial correlation between adjacent sub data sets in the specific sub data sets, andto connect the specific sub data sets to generate images of the full 3D volume at the different time phases.
