Abstract

A stereotaxic frame worn during computed tomographic (CT) scanning of the head produces landmarks in each section that are used to relate section coordinates to frame coordinates. 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.
