Abstract
An ultrasonic diagnostic imaging system is are described in which the component ultrasonic images which are to be spatially compounded are corrected for misregistration prior to compounding. The component images may be registered to a reference image or registered to form intermediate compound images which are then registered and compounded. The misregistration may be sensed by calculating a similarity or difference metric for a region of interest of the image frames being registered, or on the basis of reference lines acquired for the purpose of registering images.
Claims15
An ultrasonic diagnostic imaging system, including an array transducer which is operated to acquire images at a plurality of different electronically steered look directions, comprising:
- a resampler which spatially registers differently steered component images of a compound image in consideration of motional effects prior to compounding;
- and
- a compound image processor, responsive to said resampler, which compounds images of different look directions to form a spatially compounded image.
