This paper presents a method of compressing and restructuring an image based on a single, major feature found in the image, for example, the outline of the skull in a scene that represents a cross-section of a human head. It is a second generation method that is not based on exploiting aspects of the human visual system, but instead the restructuring of the source file in a more compact form without loss. The image domain for the evaluation of the technique is that of medical images recorded in a raster array format by a magnetic resonance scanner. An initial contour for the spiral is based on the outline derived from the image's major feature. The rest of the contours are created from this initial contour with a radius one pixel less than the most recent contour
