The aim is to provide a method for fusing the images from the individual modalities in such a way that the fusion results is an image that gives more information without any loss of the input information and without any redundancy or artefacts. For example combination of information from MRI and CT modalities gives more information than the individual modalities separately. It is needed to combine information obtained from other modalities also to improve the information acquired. In diagnosis, image obtained from a single modality like MRI, CT etc, maynot be able to provide all the required information. Medical image fusion helps in medical diagnosis by way of improving the quality of the images. Medical image fusion refers to the fusion of medical images obtained from different modalities. Image registration is the process of combining two or more images for providing more information.
