medical animation : ウィキペディア英語版
medical animation
A medical animation is a short educational film, usually based around a physiological or surgical topic, that is rendered using 3D computer graphics. While it may be intended for an array of audiences, the medical animation is most commonly utilized as an instructional tool for medical professionals or their patients.
Early medical animations were limited to basic wire-frame models because of low processor speed. However, rapid evolution in microprocessor design and computer memory has led to animations that are significantly more intricate.
The medical animation may be viewed as a standalone visualization, or in combination with other sensory input devices, such as head-mounted displays, stereoscopic lenses, haptic gloves, interactive workstations, or Cave Automatic Virtual Environments (CAVEs).
==History==
Though evolved from the field of realistic medical illustrations (such as those created by Flemish anatomist Andreas Vesalius in the 16th century), medical animations are also indebted to motion picture technology and computer-generated imagery.
The term ''medical animation'' predates the advent of computer-generated graphics by approximately three decades. Though the first computer animation was created at Bell Telephone Labs in 1963,〔("The World's First Computer Animation: Created by Edward E. Zajac of AT&T Bell Laboratories." ) Eller College of Management. University of Arizona.〕 the phrase "medical animation" appears in scholarly contexts as early as 1932 in the Journal of Biological Photography. As discussed by Clarke and Hoshall, the term referred to two-dimensional illustrated motion pictures produced for inclusion in films screened for medical students.〔(''Illustration: Its Technique and Application to the Sciences''. ) Clarke CD and Hoshall EM. John D. Lucas Company. 1939. pp 386.〕
The creation of the computer-generated medical animation began in earnest in the early 1970s. The first description of the use of 3D computer graphics for a medical purpose can be found in an issue of the journal ''Science'', dated 1975. Its authors, a team of researchers from the Departments of Chemistry and of Biochemistry and Biophysics at Texas A&M University, described the potential uses of medical animation for visualizing complex macromolecules.
By the late 1980s, the medical animation had become a distinct modality of physiological and surgical instruction. By that point, researchers had suggested that the 3D medical animations could illustrate physiological, molecular or anatomical concepts that might otherwise be infeasible.
Today's medical animation industry comprises one facet of the non-entertainment computer animation industry, which has annual revenues of $15 billion per year worldwide.〔Prayag A. ("Medical animation gaining importance." ) ''Hindu Business Line''. Bangalore. October 14, 2007.〕
