In view of experimental contrast for several methods of edge detection in the past, and combining the processing of thallium-201 myocardial perfusion image, a new edge detecting method called "Improved R. S. Method "has been developed in this paper. It is proved by experiments that this new method has a high ability to resist noise and disturbance, and has more flexibility in other application areas. In order to make the new method more objective and reliable, the iterative computation is applied to calculate the gravity center of edge, and, the Fast Fourier Transformation (FFT) makes the edge optimizing. The edge obtained by this method can be easily used in quantitative analysis of nuclear medical image, the result is quite satisfactory.
