|---|---|---|---|
| 설명 | 전자총에서 나오는 속도가 거의 균일한 전자의 연속적 흐름. X선과 마찬가지로 분자나 결정격자에 의해 전자빔의 간섭, 회절 효과를 관측할 수 있어서 분자의 구조를 알아내는 데 사용을 할 수가 있다. 그리고 물체에의 전자의 조사에 이용되기도 하는데, 악성종양에 대한 전자선 요법으로서는 라듐 B 또는 메소토륨같은 방사성 물질을 환부 가까이 위치시켜서 직접 전자선을 투여하여 악성 종양을 치료하는 방법이 있다. |

| anaesthetic depth | The degree of central nervous system depression produced by a general anaesthetic agent; a function of potency of the anaesthetic and the concentration in which it is administered. (05 Mar 2000) |
| depth | Distance from the surface downward. (05 Mar 2000) |
| depth compensation | In ultrasonography, an increase in receiver gain with time to compensate for loss in echo amplitude with depth, usually due to attenuation. Synonym: attenuation compensation, depth compensation, time compensation gain, time-compensated gain, time-varied gain control, time-varied gain. (05 Mar 2000) |
| depth dose | The dose of radiation at a distance beneath the surface, including secondary radiation or scatter, in proportion to the dose at the surface. (05 Mar 2000) |
| depth of field | <microscopy> The depth or thickness of the object space that is simultaneously in acceptable focus. The distance between the closest and farthest objects in focus within a scene as viewed by a lens at a particular focus and with given settings. The depth of field varies with the focal length of the lens and its f-stop setting or numerical aperture, and the wavelength of light. Depth of fields only a small fraction of a micrometre can be achieved at 546 nm with microscope lenses of N.A. Greater than 0.9. (05 Aug 1998) |
| depth of focus | <microscopy> The depth or thickness of the image space that is simultaneously in acceptable focus. The range of distances between a lens and image plane (target in the video pickup device) for which the image formed by the lens at a given setting is clearly focused. With a high-numerical aperture microscope objective, the depth of field is very shallow, but the depth of focus can be quite deep and reach several millimetres. (05 Aug 1998) |
| depth perception | Perception of three-dimensionality. (12 Dec 1998) |
| depth psychology | The psychology of the unconscious, especially in contrast with older (19th century) academic psychology dealing only with conscious mentation; sometimes used synonymously with psychoanalysis. (05 Mar 2000) |
| depth recording | Study of subcortical cerebral electrical activity after placing electrodes in these areas. (05 Mar 2000) |
| field depth | <microscopy> The thickness of the object space within which objects focused by a lens will all appear in good simultaneous focus. Penetration is a synonym. (05 Aug 1998) |
| focal depth | Depth of focus, the greatest distance through which an object point can be moved while maintaining a clear image. Synonym: penetration. (05 Mar 2000) |
| advanced multiple-beam equalization radiography | A variant of scanning equalization radiography using several X-ray beams. (05 Mar 2000) |
| Balkan beam | An overhead frame, supported on uprights attached to the bedposts or to a separate stand, from which a splinted limb is slung in the treatment of fracture or joint disease. Synonym: Balkan beam, Balkan splint. (05 Mar 2000) |
| beam | <radiobiology> Stream of particles or electromagnetic radiation travelling in a single direction. (09 Oct 1997) |
