摘要：
A low complexity motion compensating beamforming system and method thereof is disclosed. By detecting a beamforming range of each firing as a region of interest (ROI), and generating beam vectors according to a overlapping area of the ROI, and using a cross-correlation and the beam vectors to analyze corresponding low resolution images (LRIs), and calculating a offset according to the analysis result for sequentially compensating and combining the LRIs so as to form a high resolution image (HRI). The mechanism is help to improve the quality of beamforming and the frame rate.一種低複雜度位移補償波束成像系統及其方法,透過探頭陣列以合成孔徑的方式發射成像,並且將每次發射的成像範圍作為注意區域,以及將相鄰的注意區域的重疊部分作為重疊注意區域,接著根據重疊注意區域的中間影像束生成影像束向量,以便對相應的低解析度影像進行相依性分析,並且根據分析結果計算位移量以補償低解析度影像後,再結合所有低解析度影像以產生高解析度影像,用以達成提高超音波成像品質及畫面更新率之技術功效。110‧‧‧探頭陣列120‧‧‧成像模組130‧‧‧向量模組140‧‧‧補償模組150‧‧‧生成模組
