对腹部CT扫描进行了改进，插入了10个模拟结肠息肉，使用的方法非常接近自然发生的息肉的衰减、噪声和息肉-结肠壁界面。基于形状的息肉检测器成功定位了10个息肉中的6个。当选择增强息肉边缘轮廓的设置时，10个息肉中有8个被检测到。没有假阳性检测。形状分析在技术上是可行的，是一种很有前途的自动息肉检测方法。
An abdominal computed tomographic scan was modified by inserting 10 simulated colonic polyps with use of methods that closely mimic the attenuation, noise, and polyp-colon wall interface of naturally occurring polyps. A shape-based polyp detector successfully located six of the 10 polyps. When settings that enhanced the edge profile of polyps were chosen, eight of 10 polyps were detected. There were no false-positive detections. Shape analysis is technically feasible and is a promising approach to automated polyp detection.
