1. A low complexity motion compensating beamforming system, comprising:
a probe array, which includes I probes and J of the probes to fire for beamforming at the same time, where I and J are positive integers and J<I; an imaging forming module, which controls the probe array to continuously use J different probes in the probe array to fire for beamforming, the beamforming range of each firing is taken as a region of interest (ROI), and the different ROI's are used to generate in sequence first to K-th low resolution images (LRI's), where K is a positive integer; a vector module, which takes in sequence the overlapped region of each two adjacent ROI's as an overlapping ROI, and uses the central image beam of the overlapping ROI to generate at least one image beam vector; a compensating module, which uses a cross-correlation function to analyze the correlation between the LRI's corresponding to the image beam vectors, and uses the analysis result to compensate in sequence the second to K-th LRI's and to generate in sequence first to (K−1)-th low resolution compensating images; and a generating module, which combines the first LRI and the sequentially generated first to (K−1)-th low resolution compensating images to generate a high resolution image (HRI). |
