Tests verifying that adequate perfusion exists are a part of a patient’s assessment process that are performed by medical or emergency personnel. During major surgery, especially cardiothoracic surgery, perfusion must be maintained and managed by the health professionals involved, rather than left to the body’s homeostasis alone. In 1920, August Krogh was awarded the Nobel Prize in Physiology or Medicine for his discovering the mechanism of regulation of capillaries in skeletal muscle. Malperfusion can refer to any type of incorrect perfusion though it usually refers to hypoperfusion. The meaning of the terms “overperfusion” and “underperfusion” is relative to the average level of perfusion that exists across all the tissues in an individual body.
In the case of skin cells, extra blood flow in them is used for thermoregulation of a body. Many types of tumors, and especially certain types, have been described as “hot and bloody” because of their overperfusion relative to the body overall. Overperfuson and underperfusion should not be confused with hypoperfusion and hyperperfusion, which relate to the perfusion level relative to a tissue’s current need to meet its metabolic needs. In equations, the symbol Q is sometimes used to represent perfusion when referring to cardiac output. Microspheres that are labeled with radioactive isotopes have been widely used since the 1960s. Radioactively labeled particles are injected into the test subject and a radiation detector measures radioactivity in tissues of interest. In the 1990s, methods for using fluorescent microspheres became a common substitute for radioactive particles.
The first is based on the use of an injected contrast agent that changes the magnetic susceptibility of blood and thereby the MR signal which is repeatedly measured during bolus passage. Perfusion can be determined by measuring the total thermal diffusion and then separating it into thermal conductivity and perfusion components. CBF is usually measured continuously in time.

Jump to navigation Jump to search This article is about motion pictures that enhance the illusion of depth perception, as opposed to the traditional motion pictures displayed on flat 2D screens. 3D films have existed in some form since 1915, but had been largely relegated to a niche in the motion picture industry because of the costly hardware and processes required to produce and display a 3D film, and the lack of a standardized format for all segments of the entertainment business. This section needs additional citations for verification. The stereoscopic era of motion pictures began in the late 1890s when British film pioneer William Friese-Greene filed a patent for a 3D film process. In his patent, two films were projected side by side on screen.
The viewer looked through a stereoscope to converge the two images. On June 10, 1915, Edwin S. Waddell presented tests to an audience at the Astor Theater in New York City. Audience wearing special glasses watch a 3D “stereoscopic film” at the Telekinema on the South Bank in London during the Festival of Britain 1951. The earliest confirmed 3D film shown to an out-of-house audience was The Power of Love, which premiered at the Ambassador Hotel Theater in Los Angeles on 27 September 1922. Early in December 1922, William Van Doren Kelley, inventor of the Prizma color system, cashed in on the growing interest in 3D films started by Fairall’s demonstration and shot footage with a camera system of his own design.
Teleview system, which had been shown to the trade and press in October. Teleview was the first alternating-frame 3D system seen by the public. In 1922, Frederic Eugene Ives and Jacob Leventhal began releasing their first stereoscopic shorts made over a three-year period. The first film, entitled Plastigrams, was distributed nationally by Educational Pictures in the red-and-blue anaglyph format. The late 1920s to early 1930s saw little interest in stereoscopic pictures.
In Paris, Louis Lumiere shot footage with his stereoscopic camera in September 1933. The following March he exhibited a remake of his 1895 short film L’Arrivée du Train, this time in anaglyphic 3D, at a meeting of the French Academy of Science. In 1936, Leventhal and John Norling were hired based on their test footage to film MGM’s Audioscopiks series. The prints were by Technicolor in the red-and-green anaglyph format, and were narrated by Pete Smith.
The first film, Audioscopiks, premiered January 11, 1936, and The New Audioscopiks premiered January 15, 1938. Unlike its predecessors, this short was shot with a studio-built camera rig. Prints were by Technicolor in red-and-blue anaglyph. While many of these films were printed by color systems, none of them was actually in color, and the use of the color printing was only to achieve an anaglyph effect.
