We present a new algorithm for segmenting organs in CT scans for radiotherapy treatment planning. Given a contour of an organ that is segmented in one image, our algorithm proceeds to segment contours that identify the same organ in the consecutive images. Our technique combines partial differential equations-based morphing active contours with algorithms for joint segmentation and registration. The coupling between these different techniques is done in order to deal with the complexity of segmenting ''real'' images, where boundaries are not always well defined, and the initial contour is not an isophote of the image.
Keywords: CT scans, registration, morphing, segmentation, active contours..
