medical holography

An expanding field for holotechnology applied science uses is the practice of medicine. Holographic science can function for diagnostic purposes, treatment, education, and study. It has already been used in ophthalmology, radiology, dentistry, otology, pathology and orthopedics. Early medical applications of holotechnology science have supported imaging, such as: holographic interferograms; holography with pulses that are temporally gated; endoscopic holography; and holographic contour generation. Holographic imaging with time gated pulses gives clear viewing of objects surrounded by semi-transparent material, especially body tissues or semi-transparent tissue. This makes it a first-rate method of imaging for many biomedical applications. Medical holography can give three-dimensional images of internal body structures to aid in diagnostics and surgical planning. See also Holographic data storage .

Holodisks may be created by combining two different layers of polymer. One layer does not respond much with lasers, but gives structural support for the disk. The other layer does not have much internal support, but reacts well with the laser and is connected to the structural layer. The use of two different slices makes it possible for the creation of holographic disks that are both solid and optically sensitive. Several types of substances have been tested as potential holographic recordable media, including iron-doped lithium- niobate crystal and stoichiometric lithium niobate. Included in the alternative materials for holodisks, polycarbonate materials may be chemically altered when lit by a certain type of laser. Due to their preliminary high cost, holotechnology information disks are likely to be first used for high-resolution digital video broadcasting and movie distribution for digital theaters.
