Ultrasonic imaging apparatus and method for acquiring ultrasonic image

An ultrasonic imaging apparatus comprising:

• a scanner configured to ultrasonically scan an inside of a subject body;
• an image generator configured to generate 3-dimensional B-mode image data showing a shape of the inside of the subject body and 3-dimensional colored Doppler image data showing blood flow, based on data acquired through scan by the scanner;
• a marker generator configured to generate a first planar marker, a second planar marker and a third planar marker that are movable and cross each other;
• and
• a display controller configured to cause a display to display the first planar marker, the second planar marker and the third planar marker so as to be superimposed on a 3-dimensional B-mode image based on the 3-dimensional B-mode image data and a 3-dimensional colored Doppler image based on the 3-dimensional colored Doppler image data, wherein:
• the display controller causes the display to display the 3-dimensional colored Doppler image in an attention region on a preset viewpoint side of regions sectioned by the first planar marker, the second planar marker and the third planar marker;
• the scanner receives coordinate information of an intersection of the first planar marker, the second planar marker and the third planar marker from the marker generator, and executes Doppler scan on a site corresponding to the intersection;
• and
• the image generator generates Doppler data showing blood-flow information at the intersection, based on data acquired through the Doppler scan.
