FUSION OF SPECT AND MRI IMAGES USING BACK AND FORE GROUND INFORMATION

Perception and diagnosis of disorders by usingsingle photon emission computed tomography (SPECT) image isdifficult since this image does not contain anatomicalInformation. In the studies it is tried to make innovation SPECTimage by magnetic resonance imaging (MRI) and image fusionmethods. So the fused image is obtained involving functional andanatomical information. MRI image shows tissue brain anatomyand it has high spatial resolution without functional information.SPECT shows brain function and it has low spatial resolution.Fusion of SPECT and MRI images leads to a high spatialresolution image. The fused image with desired specificationsconsists in spatial and spectral distortions. Substitution methodssuch as IHS and Multi-resolution fusion methods such as wavelettransform preserve spatial and spectral information respectively.In This article we present a method that preserves both spatialand spectral information well and minimizes distortions of fusedimages relative to other method
