Segmentation fusion of image with meningoma

Possessing both merits and demerits respectively, CT and MRI test are the two common radiological means to diagnose meningoma. With high-density resolution, CT detects even tiny density differentia of normal tissue and tumor tissue in the brain, but can not distinguish every soft tissue as expected. MRI scans all direction of the tissues freely, and can clearly differentiate soft tissues such as muscle, fascia, fat, gray matter, white matter, and abnormal lesion, but can not accurately identify the calcified part of tumor and the boundary between tumor and cranium. In recent years, researchers around world try to register and fuse images of CT and MRI in order to achieve a new image with more information for diagnosis and differentiating diagnosis. Based on CT and MRI images of meningoma, the normal parts and tumor parts were registered, segmented and processed with weighted fusion. Pseudo color was used on the image to provide more easily recognized information in new one for early clinical diagnosis of the meningoma.
