A Survey on Analysis of MRI Images of Brain

Image analysis is a process where various computational techniques are applied on digital images to extract important information from the image and thereby significant conclusions from the concerned image can be obtained. Images having medical importance are now-a-days is the centre point of attraction in the field of image processing due to their high values and complications in nature. The present paper deals with a summary of the techniques and methods applied in analyzing the brain images. An image is normally analyzed from the perspective of its segmentation, edge detection, registration and morphology or motion analysis. Different types of brain images like MRI, CT, PET EEG are being used by the medical practitioners as the source for the detection of abnormalities in the brain. In the present paper, whole concentration has been given only on the MRI images. Lot many operations on MRI images of the brain are being applied. A study has been made on the techniques being applied for processing of MRI images of the brain and anysis has been made through their applications, modalities, advantages, limitations, efficiencies and results obtained by the researchers in this area.
