In accurate radiotherapy treatment planning system,image fusion making full use of various information of medical images provides more useful and accurate information for clinical diagnoses.However,registration is needed before fusion in order to ensure the fusion quality.Automatic image registration has been a research focus nowadays.However,it has always been a difficult problem to improve the precision and speed of registration.The paper presented a multi-resolution automatic registration algorithm based on mutual information by using ITK and VTK.In this paper principle and implementation flow of this algorithm were described in detail.To evaluate the performance of this algorithm,clinical medical images were used for test.The results indicate that the method mentioned above can well meet the requirements of accurate radiotherapy in both precision and speed.
