本文提出一种根据配准图像之间的旋转角度大小（以模板配准结果的标准差作为旋转角度大小的度量）来选择不同配准算法（模板法或频域法）的超声宽景成像新方法。实验结果表明，本方法在超声探头存在大角度旋转时仍能快速、准确地生成被观察组织的宽景图，具有良好的实用价值。

This paper discusses a new Extended-field-of-view (EFOV) ultrasound imaging that uses different registration algorithms (block method or frequency domain method) according to the revolving angle evaluated by the standard deviation of registration results of all valid blocks. The experimental results show that the proposed method can still generate the EFOV image of the observed tissue quickly and accurately even when there is a large revolving angle, indicating good practical values.
