X光胸片中肋骨信息自动提取算法及实现

Automatically-Extracted Algorithm of Rib Information in Chest X-ray Image and Its Implementation

在分析X光胸片图像及肋骨特点的基础上,提出了符合医学规范的肋骨信息自动提取步骤及相应算法.此算法充分利用图像中值滤波、边缘提取、种子跟踪、抛物线拟合等相关的一些图像处理技术,并结合X光胸片中肋骨线的生物学特点,最终实现了图像处理技术在一个具体实例中的成功应用.将该算法应用于具体实例———肺结核病灶自动定位,取得较好的定位速度和准确度.

Based on the feature analysis of the X-ray films of chest and the rib, the paper presents an algorithm to realize the automatic feature recognition of the rib frame by the physic regulations. This algorithm is successfully implemented in a case study on the basis of the image processing technologies such as the value of filtering, edge detection, tracking seed, parabolic fitting, and some other related image processing technologies with a consideration of the biological characteristics of the ribs in X-ray chest film. The ease study on phthisis for locating the focus proves the efficiency and the precision of the algorithm.
