A small, commercially available, programmable calculator is used to interrelate frame and CT section geometry. The system can be used with any CT scanner that can specify (x,y) coordinates of a pixel, obviating the need for extensive modifications of the CT computer software. Representative clinical cases are presented. %U https://www.ajnr.org/content/ajnr/2/2/181.full.pdf
