|---|---|---|---|
| 설명 | 핵의학적 진단방법중 하나. 가장 발달된 형태의 핵의학적 진단방법이다. 양전자를 방출함으로써 생기는 핵의학적 방사능을 이용하여 인체의 단면을 촬영할 수 있다. 이것은 마치 컴퓨터단층촬영과 유사하나, 조영제와 X-선을 사용하지 않는다는 점에서 다르다. 이용하는 핵의학적 물질을 인체내에서 대사가능한 물질(예를 들어 포도당, 혹은 지방)에 붙여서 사용함으로써, 실제적으로 살아있는 생체내에서 어떤 형태로 대사가 이루어지는 지 알아낼 수도 있다. 예를 들면, 눈을 뜨고 어떤 물체를 주시할 때, 뇌의 어떤 부위가 가장 활발한 대사작용을 하는지 알 수 있다. |

| otoacoustic | Referring to the very faint sounds produced by the ear; thought to represent mechanical vibrations in the cochlea. (05 Mar 2000) |
|---|---|
| otoacoustic emissions, spontaneous | Sinusoidal tones originating in the cochlea. These faint sounds, with levels between 10-30 decibels, are usually not recognised by the persons having them. However, the emissions can be recorded using sensitive microphones placed in the ear canals. The clinical significance of having or not having spontaneous otoacoustic emissions is unclear; however, some association between tinnitus and the spontaneous emissions has been reported. (12 Dec 1998) |
| barrel distortion | <microscopy> A distortion, or aberration. (05 Aug 1998) |
| geometrical distortion | <microscopy> A lens aberration in which the image is distorted relative to the object. See: aberration, barrel distortion, distortion, pincushion distortion. (05 Aug 1998) |
| perceptual distortion | Lack of correspondence between the way a stimulus is commonly perceived and the way an individual perceives it under given conditions. (12 Dec 1998) |
| pincushion distortion | <microscopy> A geometrical distortion in a video picture, or a form of optical aberration, that makes the middle of all sides of a square appear to bow inward. The distortion can amount to several percent of the picture height in some intensified camera tubes. See: Aberration, Distortion, Barrel distortion. (05 Aug 1998) |
| specimen distortion | <microscopy> A physical change in the specimen caused by desiccation or heating by the electron beam. (05 Aug 1998) |
| distortion | The state of being twisted out of a natural or normal shape or position. Origin: L. Dis = apart, torsio = a twisting (18 Nov 1997) |
| distortion aberration | The faulty formation of an image arising because the magnification of the peripheral part of an object is different from that of the central part when viewed through a lens. (05 Mar 2000) |
| alpha emission | <physics> Form of nuclear decay where the nucleus emits an alpha particle (see entry below). (09 Oct 1997) |
| beta emission | <radiobiology> Form of nuclear decay where a neutron splits into a proton plus electron plus neutrino set. The proton stays in the nucleus but the electron (beta ray) is ejected. (09 Oct 1997) |
| gamma emission | <physics> Nuclear decay process whereby the nucleus goes from an excited state to a more stable state by emitting a gamma ray. See: gamma ray. (09 Oct 1997) |
| particulate emission | Fine liquid or solid particles discharged with exhaust gases. Usually measured as grains per cubic foot or pounds per million Btu input. (05 Dec 1998) |
| characteristic emission | Monochromatic radiation that is produced when an electron is ejected from an atom and another takes its place by jumping from another shell; the energy of the photon is the difference between that of the two shell positions. Synonym: characteristic emission. (05 Mar 2000) |
| microscope, field emission | <microscopy> An image-forming device in which a strong electrostatic field causes cold emission of electrons from a sharply rounded point or from a specimen that has been placed on that point. The electrons are accelerated to a phosphorescent screen, or photographic film, giving a visible picture of the variation of emission over the specimen surface. (05 Aug 1998) |
