由于利用边缘检测使增长环搜寻所需的扫描范围在很大程度上缩小,最小不连续相位展开算法的效率得到了很大提高。
Because the required scanning range is cut down to a large extent by use of edge detection methods, the efficiency of the minimum-discontinuity phase unwrapping algorithm is significantly improved.
延时,脓肿周围低密度水肿环可强化为等密度,或脓肿内部强化,病变范围缩小,液化坏死区更显明显。
Delayed scan, the hypodense edema ring enhanced and became isodense, or the abscess enhanced diffusely, the lesions became smaller and the colliquative necrosis area more obvious.
