In this paper we discuss what is required for the accurate and complete display of three-dimensional tomographic medical data. Both holographic stereograms and volumetric-multiplexed holograms have been used for the display of such data. We describe these two kinds of hologram, and compare them with several other display techniques including conventional two-dimensional images and pseudo-three-dimensional pictures generated using computers. The suitability of dispersion-compensated volumetric-multiplexed holography for the display of tomographic medical data derives from its ability to provide near-range physical depth cues, its ability to show all of the information in a volume without obscuration, its inherent geometric and photometric accuracy, and its similarity to conventional film-based hard copies. The showing of all information within a volume is a fundamental requirement for the display of soft tissues in tomographic medical data, but is generally undesirable for certain other three-dimensional display purposes such as Computer Aided Design. The combined effect of having the near-range physical depth-cues and showing all of the volume information provides a solution to the so-called "cloud-in-a-cloud" problem which has been significant for other display techniques.
