| 설명 | 치료방사선과에서 이용하는 기계로서 전자를 생성해 낸다. 전자는 단순히 X-선과는 다른 것으로 전자가 금속에 부딪혀 나오는 것이 X-선이다. 전자는 진단목적보다는 치료목적으로 주로 피부의 악성종양(암)에 사용된다. |

| perspective | 1. A glass through which objects are viewed. "Not a perspective, but a mirror." 2. That which is seen through an opening; a view; a vista. "The perspective of life." 3. The effect of distance upon the appearance of objects, by means of which the eye recognised them as being at a more or less measurable distance. Hence, aerial perspective, the assumed greater vagueness or uncertainty of outline in distant objects. "Aerial perspective is the expression of space by any means whatsoever, sharpness of edge, vividness of colour, etc." (Ruskin) 4. The art and the science of so delineating objects that they shall seem to grow smaller as they recede from the eye. Synonym: linear perspective. 5. A drawing in linear perspective. Isometrical perspective, an inaccurate term for a mechanical way of representing objects in the direction of the diagonal of a cube. Perspective glass, a telescope which shows objects in the right position. Origin: F. Perspective, fr. Perspectif: cf. It. Perspettiva. See Perspective. 1. Of or pertaining to the science of vision; optical. 2. Pertaining to the art, or in accordance with the laws, of perspective. Perspective plane, the plane or surface on which the objects are delineated, or the picture drawn; the plane of projection; distinguished from the ground plane, which is that on which the objects are represented as standing. When this plane is oblique to the principal face of the object, the perspective is called oblique perspective; when parallel to that face, parallel perspective. <zoology> Perspective shell, any shell of the genus Solarium and allied genera. See Solarium. Origin: L. Perspicere, perspectum, to look through; per + spicere, specere, to look: cf. F. Perspectif; or from E. Perspective, n. See Spy. Source: Websters Dictionary (01 Mar 1998) |

| Haworth perspective formula | <biochemistry> Of cyclic sugars, perspective representations of furanose or pyranose structures as pentagons or hexagons, respectively, with the connecting bonds so shaded as to make them appear as though the plane of the ring is at an angle of 30 |
| programming, linear | A technique of operations research for solving certain kinds of problems involving many variables where a best value or set of best values is to be found. It is most likely to be feasible when the quantity to be optimised, sometimes called the objective function, can be stated as a mathematical expression in terms of the various activities within the system, and when this expression is simply proportional to the measure of the activities, i.e., is linear, and when all the restrictions are also linear. It is different from computer programming, although problems using linear programming techniques may be programmed on a computer. (12 Dec 1998) |
| non-linear | Not linear. (05 Dec 1998) |
| superficial linear keratitis | Spontaneous, painful keratitis with epithelial erosion and folds in Bowman's membrane. (05 Mar 2000) |
| linear | Pertaining to or resembling a line. Origin: L. Linearis (18 Nov 1997) |
| linear absorption coefficient | That fraction of ionizing radiation absorbed in a unit thickness of a substance or tissue. See: absorption coefficient. (05 Mar 2000) |
| linear acceleration | The rate of change of velocity without a change in direction; e.g., when the speed of an aircraft increases while flying a straight pathway. (05 Mar 2000) |
| linear accelerator | <apparatus> A sophisticated external beam radiotherapy machine which has the capabilities of focussing irradiation (although not very finely). Acronym: LinAC (16 Dec 1997) |
| linear amputation | Amputation performed by a circular incision through the skin, the muscles being similarly divided higher up, and the bone higher still. Synonym: guillotine amputation, linear amputation. (05 Mar 2000) |
| linear atrophy | Bands of thin wrinkled skin, initially red but becoming purple and white, which occur commonly on the abdomen, buttocks, and thighs at puberty and/or during and following pregnancy, and result from atrophy of the dermis and overextension of the skin; also associated with ascites and Cushing's syndrome. Synonym: atrophoderma striatum, lineae albicantes, lineae atrophicae, linear atrophy, stretch marks, stria, striae atrophicae, striate atrophy of skin, traction atrophy, vergeture. (05 Mar 2000) |
| linear dichroism | <chemistry> Differential absorption of right hand and left hand circularly polarized light resulting from molecular asymmetry involving a chromophore group. Circular dichroism is used to study the conformation of proteins in solution. (18 Nov 1997) |
| linear energy transfer | <radiobiology> Average amount of energy lost per unit of particle track length and expressed in keV um-1. Acronym: LET (16 Dec 1997) |
| linear epidermal nevus | A congenital systematised linear nevus limited to one side of the body or to portions of the extremities on one side; lesions are often extensive, forming wave-like bands on the trunk and spiraling streaks on the extremities. Synonym: linear epidermal nevus. (05 Mar 2000) |
| linear fracture | A fracture running parallel with the long axis of the bone. Synonym: fissured fracture. (05 Mar 2000) |
| linear perspective | the appearance of things relative to one another as determined by their distance from the viewer |
