holographic imaging in the field of medicine

Holographic methodologies can be applied to three-dimensional (3-D) rendering of medical images including MRI and CT pictures. Medical holographic imaging can allow doctors to test the insertion of medical instruments into an artificially constructed, 3D version of the surgical field before the procedure. An array of micro- mirrors, whose motions are directed by computer, can function to fragmentize and redirect an array of laser rays to make animated, 3D holographic images of internal anatomic features. Sub-page Wasatch Photonics covers these issues as well.

Holotech science offers the potential to save data throughout the volume of a medium, not merely on its surface. A holographic image containing an entire million-bit page of data is recorded within a photosensitive storage medium when a reference laser beam and a signal laser beam (containing recorded data) intersect within the storage media. To retrieve a holographic page of information that was recorded in photosensitive media, a reference laser beam is shown into the storage media at the identical angle used to make the page originally. The ray is diffracted by the storage media and the image of the original page reappears. This reconstructed page is then projected into a Charge Coupled Device (CCD) camera that converts the holographic data picture back into electronic digital data. This information may then be processed via computer. Given the evolution of holotechnology information storage, it can be possible to store movies, video games, and interactive maps on holocards that are as small as postage stamps. Virtual Reality Cafe also covers related topics.

Holographic Displays also has information about this.
