Abstract:
Objective To provide new diagnose informations for clinician by using image fusion. Methods 30 cases with brain lesion (men 18,women were studied 12). Twenty cases were examined by CT or MR in 1_2 weeks, the others were checked by MR, after being diagnosed with CT. These image data were input into computer the center and main axis of image were located by Legendre moment then the CT and MR images were registered by translation, scaling and rotation. Results Of 30 image fusions, supplementary informations were provided to each other in 28 cases,prediction of disease progress in 19 cases. There were 4 cases confirmed at surgery. But in 2 cases no obvious advantage was obtained by image fusion.Conclusion CT and MR image fusion provides useful information for definitive diagnosis, planning of surgery and radiotherapy. To fuse the images of CT and MR, the Legendre moment approach is direct, simple and fast.
