摘要:

在INFN支持的MAGIC-5意大利项目的框架内,正在开发一个计算机辅助检测系统,用于在1.25毫米层厚的低剂量多探测器螺旋CT图像中识别肺结节。我们的肺CAD系统的基本模块,结节候选人选择的点增强过滤器和基于体素的神经分类器的假阳性发现减少,进行了描述。初步结果上迄今收集的肺部CT扫描数据库进行了讨论。

英文摘要:

A computer-aided detection (CAD) system for the identification of pulmonary nodules in low-dose multi-detector helical CT images with 1.25 mm slice thickness is being developed in the framework of the INFN-supported MAGIC-5 Italian project. The basic modules of our lung-CAD system, a dot enhancement filter for nodule candidate selection and a voxel-based neural classifier for false-positive finding reduction, are described. Preliminary results obtained on the so-far collected database of lung CT scans are discussed.
