| 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 fracture | A fracture running parallel with the long axis of the bone. Synonym: fissured fracture. (05 Mar 2000) |
| linear IgA bullous disease in children | A rare self-limiting bullous disease, chiefly of the trunk, perioral, and pelvic areas, with onset in the first decade, successively less severe recurrences, and total remission at adolescence; linear epidermal basement membrane zone deposit of IgA is found in involved and in normal skin. Synonym: linear IgA bullous disease in children. (05 Mar 2000) |
| linear models | Statistical models in which the value of a parameter for a given value of a factor is assumed to be equal to a + bx, where a and b are constants. The models predict a linear regression. (12 Dec 1998) |
| linear skull fracture | A skull fracture resembling a line. (05 Mar 2000) |
| acquired nevus | A melanocytic nevus that is not visible at birth, but appears in childhood or adult life. (05 Mar 2000) |
| balloon cell nevus | A nevus in which many of the cells are large, with clear cytoplasm. (05 Mar 2000) |
