Image Fusion On MR And CT Images

Medical imaging has emerged as one of the most important tools to identify as well as diagnose various disorders. The main objective of medical imaging is to obtain high resolution image details as with as much details as possible for correct diagnosis. There are several medical imaging techniques such as MRI and CT imaging techniques. Both give special sophisticated characteristics of the organ to be imaged. So it is expected that fusion of MRI and CT images of same organ would result in an integrated image of much more details. Many algorithms and tools have been developed for fusing panchromatic and multispectral images. A image fusion algorithm based on wavelet transform to fuse two images is presented in this paper. When images are merged in wavelet space, different frequency ranges are processed differently. It can merge information from original images adequately and improve abilities of information analysis and feature extraction. Wavelet transform of two input images is taken together with fusion rule. Then, inverse wavelet transform is computed to reconstruct fused image.
