1. A method of teaching X-ray techniques which comprises: (a) providing a storage bank of individual X-ray shots of a particular object to be examined radiographically, each taken with the X-ray beam directed sequentially at a multiplicity of angles, (b) positioning a simulated X-ray source adjacent a representation of said particular portion of the object for a particular X-ray analysis, and (c) displaying one of said X-ray shots selected by the positioning of the simulated X-ray source to enable a student to develop skill in such positioning.
