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

| 설명 | 의사가 종이 대신 컴퓨터에 직접 환자의 임상정보를 입력하면 이를 데이터베이스화하여 새로운 정보로 가공-생성하는 의료정보시스템. 환자의 진료기록을 찾아 진료실에 전달하고 다시 처방전을 받아 조제하는 일련의 과정이 네트워크로 처리돼 환자대기시간이 대폭 줄고, 별도의 진료기록실이 불필요하다. |

| refractory period of electronic pacemaker | The time required to restore full sensitivity after detecting cardiac activity or delivering a pacing impulse. (05 Mar 2000) |

| Mueller electronic tonometer | A Schiotz type tonometer that electronically indicates the extent of corneal indentation; may also have an attached recorder for continuous pressure readings (tonography). (05 Mar 2000) |
| electronic | 1. Pertaining to electrons. 2. Denoting devices or systems utilizing the flow of electrons in a vacuum, gas, or saemiconductor. (05 Mar 2000) |
| electronic cell counter | <apparatus, haematology> An automatic blood cell counter in which cells passing through an aperture alter resistance and are counted as voltage pulses, or in which cells passing through a flow cell deflect light. Some types of counter are capable of multiple simultaneous measurements on each blood sample; e.g., leukocyte count, red cell count, haemoglobin, haematocrit, and red cell indices. (21 Jun 2000) |
| electronic number | <chemistry> The number of electrons in the outermost orbit (valence shell) of an element. (05 Mar 2000) |
| electronic pacemaker | An electric device that can substitute for the normal cardiac pacemaker, controlling the heart's rhythm by artificial electric discharges. Synonym: electronic pacemaker. (05 Mar 2000) |
| electronic pacemaker load | The impedance to the output, the standard load being 500 ohms resistance ± 1%. (05 Mar 2000) |
| electronic potential | <chemistry, physiology> The measure (in volts) of electron pressure. A measure of the difference in electron concentrations between two compartments, such as either side of a cell membrane. (09 Oct 1997) |
| 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) |
| positron emission tomography | <radiology> A highly specialised research imaging technique using short lived radioactive substances - usually those made with a cyclotron. This technique is very sensitive in picking up active tumour tissue but does not measure the size of it. Tomographic images are formed by computer analysis of photons detected from annihilation of positrons emitted by radionuclides incorporated into biochemical substances; the images, often quantitated with a colour scale, show the uptake and distribution of the substances in the tissue, permitting analysis and localization of metabolic and physiological function. Because the half-lives of the radionuclides are so short (20 minutes to 2 hours), and the equipment expensive, PET is rarely used in a clinical setting. But since its development in the mid-1970s, it has proved the most important tool yet devised for experimental investigation of the living brain, whether healthy, traumatised, or diseased. With CT and MRI, it represents a new generation of computer imaging techniques that have revolutionised medicine and physiology. Acronym: PET (20 Jun 2000) |
