|---|---|---|---|
| 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. |

| spectrophotometer | A machine used to measure how much light of a given wavelength is absorbed by a liquid sample, or to measure how intense (bright) the spectral lines and bands produced by the sample are, relative to each other. (09 Oct 1997) |
| flame | 1. A stream of burning vapor or gas, emitting light and heat; darting or streaming fire; a blaze; a fire. 2. Burning zeal or passion; elevated and noble enthusiasm; glowing imagination; passionate excitement or anger. "In a flame of zeal severe." "Where flames refin'd in breasts seraphic glow." (Pope) "Smit with the love of sister arts we came, And met congenial, mingling flame with flame." (Pope) 3. Ardor of affection; the passion of love. 4. A person beloved; a sweetheart. Synonym: Blaze, brightness, ardor. See Blaze. Flame bridge, a bridge wall. See Bridge. Flame colour, brilliant orange or yellow. Flame engine, an early name for the gas engine. Flame manometer, an instrument, invented by Koenig, to obtain graphic representation of the action of the human vocal organs. See Manometer. <chemistry> Flame reaction, a method of testing for the presence of certain elements by the characteristic colour imparted to a flame; as, sodium colours a flame yellow, potassium violet, lithium crimson, boracic acid green, etc. Cf. Spectrum analysis, under Spectrum. <botany> Flame tree, a tree with showy scarlet flowers, as the Rhododendron arboreum in India, and the Brachychiton acerifolium of Australia. Origin: OE. Flame, flaume, flaumbe, OF. Flame, flambe, F. Flamme, fr. L. Flamma, fr. Flamma, fr. Flagrare to burn. See Flagrant, and cf. Flamneau, Flamingo. Source: Websters Dictionary (01 Mar 1998) |
| flame arc | An arc between two impregnated electrodes that causes volatilization of the core with resultant flame. (05 Mar 2000) |
| flame figure | A small area of dermal or subcutaneous necrosis with intense eosinophil staining of collagen bundles; seen in the lesions of Well's syndrome. (05 Mar 2000) |
| flame ionisation detector | <apparatus> A piece of equipment used in gas chromatography that uses a flame to decompose the neutral solute molecules into charged particles, then measures any changes in conductivity. (09 Oct 1997) |
| flame ionization | Pyrolysis of organic compounds at the temperature of a hydrogen-air flame to produce ionic intermediates which can be collected and the resulting ion current measured by gas chromatography. (12 Dec 1998) |
| flame retardants | Materials applied to fabrics, bedding, furniture, plastics, etc. To retard their burning; many may leach out and cause allergies or other harm. (12 Dec 1998) |
| flame spots | Haemorrhagic areas occurring in the nerve fibre layer of the retina. (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) |
