Advances in the technology of medical imaging have allowed doctors to peer into the humna body in a more realistic, less invasive manner. CT (Computerized Tomography) and API (Nagnetic Resonance Imaying) that usually obtain 2-dinensional slices of 'oatient anatomy, are alLx) capable of pi oducin 3-dimens1onal r&prosentations of in anatomy and pathology. 1,2,3,4,5,5 Further ddVaflCEO in computer data acquisition, hence decreaeo. scan times with better resolution, have allowed for cine MR and CT giving us repreentative motion in pseudotize and almost real time. We now have the capbility to construct interal holograms out of 3-dimensional reformatted CT and MR Cata that demonstrate anatorcy in "true" 3-dimensions, and in the near future, 4-cliensionL; about a single axis. 7,3 This woulC allow. a medical student to aiwciate not only still anatomy from a cavader or electronic cadaver, out also 3-dimensional interactive pseudotiae intergral holograms of moving anatomy. Holograp4 is currnLiy the only wEy of visually recording objects or camputer-graphic models into "true" 3 and 4-dimensions. Since diikensions were defined befate computer-generated graphics and co:aputer-baed igi% technologiez, subdivisiono of dimensions (factorials will be addressed for the purpose of explanation for this paper.
