This paper deals with the use of fuzzy logic and dynamic programming in the detection of cardiac contours in MR Images. The definition of two parameters for each pixel allows the construction of the fuzzy set of the cardiac contour points. The first parameter takes into account the grey level, and the second the presence of an edge. A corresponding fuzzy matrix is derived from the initial image. Finally, a dynamic programming with graph searching is performed on this fuzzy matrix. The method has been tested on several MR images and the results of the contouring were validated by an expert in the domain. This preliminary work clearly demonstrates the interest of this method, although a formal evaluation has to be done.
本文探讨了模糊逻辑和动态规划在磁共振成像（MR图像）中心脏轮廓检测中的应用。为每个像素定义两个参数，从而构建心脏轮廓点的模糊集。第一个参数考虑灰度级，第二个参数考虑边缘的存在情况。从初始图像导出相应的模糊矩阵。最后，对该模糊矩阵进行带图搜索的动态规划。该方法已在多幅MR图像上进行了测试，轮廓检测结果由该领域的专家进行了验证。尽管还需要进行正式评估，但这项初步工作清楚地表明了该方法的优势。
