Locating MRI discrepancy by orientation invariant method
چکیده انگلیسی
This research investigates the techniques using the image subtraction to find the discrepancy between healthy and illness MRI images. The technique developed in this research moves healthy MRI image to overlap with illness MRI image. Then, healthy MRI image and illness MRI image are aligned to same orientation. After the healthy MRI image overlapped with illness MRI image, illness MRI image is subtracted from healthy MRI image. If there is discrepancy between healthy and illness MRI images, after image subtraction, discrepancy will remain in the subtracted result. From beginning to end the inspection is done by machine automatically and there is no further human effort involved. The technique developed in this research can very accurately find discrepancy of healthy and illness images. This paper explains the method using second moment to find orientations of the MRI images. By the orientations of MRI images, healthy and the illness MRI image can be aligned to same orientation. Detailed process of image rotation is addressed in this paper.
