Digital Holography Helps Plastic Surgeons Reshape Abnormal Skulls of Children.SANTA FE, N.M.--(BW HealthWire)--Sept. 15, 1997--Dr. David Furnas, Chief of the Department of Plastic Surgery at the University of California-Irvine Medical Center, will report tomorrow how the Digital Holography(TM) System from Voxel(TM) (NASDAQ NASDAQ

The holograms produced by the system have helped clinicians diagnose craniofacial craniofacial /cra·nio·fa·cial/ (kra?ne-o-fa´sh'l) pertaining to the cranium and the face.

The Digital Holography System uses data routinely collected by Computed Tomography (CT) and Magnetic Resonance (MR) scanners to produce true three-dimensional images. The Voxgram(TM) images are life-size, transparent holograms that literally extend out in space, enabling physicians to interact in, around and through the image as if it were a real specimen of anatomy.
Over a period of 18 months, Dr. Furnas has used holograms made from CT data in planning his osteotomies. In this procedure, the deformed portion of the skull is cut into components that are reassembled as a self-supporting cranial cranial /cra·ni·al/ (-al)

Dr. Furnas found that six special qualities of the holograms make them particularly useful clinically. Because the image is life size, skull configuration can be evaluated precisely. Because the dimensions are faithful and the image translucent, "linear and angular measurements are true to life" and "skeletal features in the background are not obscured by those in the foreground."
For example, Dr. Furnas related that a proposed dovetail dovetail

Another important quality of the holograms is their "dynamic" perspective. Simply by changing the angle of view, the viewer can often identify "puzzling structures" and see "small or lucent objects, which are obscured from a single viewpoint." Additionally, different data sets (for example, from CT and MR angiography data) can be "fused" and the images viewed as one.
Finally, the interactive hologram allows physicians to test "templates for bone grafts or for the advancement or recession of skull components."

In addition to the research being done by Dr. Furnas, physicians at several other prominent medical institutions throughout the country have studied Digital Holography, including Massachusetts General Hospital-Harvard Medical School, Mallinckrodt Institute of Radiology, Stanford University Medical Center Stanford University Medical Center (Stanford Hospital & Clinics) is one of four hospitals affiliated with Stanford University and Stanford University School of Medicine, along with the Lucile Packard Children's Hospital, the Veteran's Administration Hospital in Palo Alto, and Santa and the Ryder Trauma Center-University of Miami.
