Creation of a Three-Dimensional Atlas by Interpolation from Schaltenbrand-Bailey's Atlas

A 0.5-mm step atlas was interpolated from Schaltenbrand-Bailey's atlas. By serial display of the atlas with the desired rotation on a three-dimensional axis, a three-dimensional atlas was created. The newly created atlas can be used for computer-processed stereotactic data display. Any three-dimensionally located point can be displayed within 0.25 mm distance from the point, and spatial understanding of anatomical structures and stereotactic data is facilitated by the three-dimensional display.
