Space-occupying lesions (SOL) and irregular intensity distribution are usually observed in the radioisotope images of human liver diseases, hepatic cancer, etc. This paper describes a new image processing method for evaluating such SOL by using a computer. This method analyzes quantitatively the convex and the concave structure of the contour line. From the processed results, the contour lines of radioisotope images of liver diseases are more ragged than those of normal ones; the region of SOL is extracted by the abnormal raggedness in the contour structure.
在人类肝脏疾病、肝癌等的放射性同位素图像中，通常会观察到占位性病变（SOL）和不规则的强度分布。本文描述了一种使用计算机评估此类SOL的新图像处理方法。该方法定量分析轮廓线的凸凹结构。从处理结果来看，肝脏疾病放射性同位素图像的轮廓线比正常图像的轮廓线更参差不齐；通过轮廓结构中的异常参差不齐来提取SOL区域。
