Patent ID: 7881774

Claim:
An apparatus for obtaining an ultrasonic image comprising: an ultrasonic probe that scans an ultrasonic beam in a main scanning direction and a sub-scanning direction; a scan device that receives a trigger signal based on an electrocardiographic waveform, drives the ultrasonic probe in accordance with the trigger signal so as to scan a plurality of regions, and obtains scan data for each region; and an image generating device configured to combine the scan data obtained for each region so as to generate ultrasonic image data of a range in which the plurality of regions are joined, wherein the scan device is configured to cause the ultrasonic probe to scan the plurality of regions so that scan data in which time phases of the electrocardiographic waveform substantially coincide are obtained in the vicinities of the boundary between at least two adjacent regions among the plurality of regions, and to divide the regions by boundaries drawn extending outward from a center point of the regions in at least two directions passing through the center point.
