Abstract
A basic image generation unit generates a base frame by synthesizing a reception frame sequence obtained by transmission/reception of ultrasonic waves, and an edge-enhanced image generation unit generates a compensation frame where an edge component of an object is emphasized based on the reception frame sequence. A synthesis unit generates an output frame by synthesizing the base frame and the compensation frame.
Claims7
An ultrasonic diagnosis device comprising:
- a base frame generation unit configured to generate a base frame by synthesizing a frame sequence obtained by transmission/reception of ultrasonic waves;
- a compensation frame generation unit configured to generate a compensation frame where an edge component is emphasized based on the frame sequence;
- and
- a synthesis unit configured to generate an output frame by synthesizing the base frame and the compensation frame;
- wherein the synthesis unit synthesizes the base frame and the compensation frame by changing a weight in an area unit or a pixel unit in the base frame and the compensation frame;
- wherein each frame included in the frame sequence is a frame where deflection angles of ultrasonic waves are different from each other;
- and
- wherein the synthesis unit sets a weight for an area where a number of frames overlapping each other is small to be smaller than a weight for an area where a number of frames overlapping each other is large in the compensation frame.
