摘　　要：通过分析ＳＰＥＣＴ心肌灌注断层图象的象素点之几何分布，利用最小二乘法拟合心肌左心室的半球加圆柱模型，采用迭代算法去除非左心室组织显影，实现左心室的自动提取。该技术为进一步定量分析提供了基础。An automatic method of extracting left ventricle from SPECT myocardialperfusion data was introduced. This method was based on the least square analysis ofthe positions of all short-axis slices pixels from the half sphere-cylinder myocardialmodel, and used a iterative reconstrution technique to automatically cut off thenon-left rentricular tissue from the perfusion images. Thereby, this techniqueprovided the bases for further quantitative analysis.
