Apparatus for three-dimensional viewing of magnetic resonance imaging tomograms |
摘要 |
A plurality of liquid crystal displays, each able to independently display one of a plurality of MRI tomograms, is dispersed such that the display screen of each appear planar from a common point and are positioned such that the spacing between each display screen and the next one in front or back and of it is proportional to the spacing between the cross sections belonging to the MRI tomograms displayed by those display screens. A hologram screen is provided in position facing the display screens of the plurality of displays. By illuminating the plurality of displays with light from behind, light passing through each of the display screens will impinge on the hologram screen, and part of this light will be diffracted backwards by the hologram screen, causing virtual images of the MRI tomograms to appear in front of the hologram screen.
