| characteristic X-ray | <microscopy> An X-ray having a unique energy that is emitted by an atom in the sample during its de-energization after ionization of one of its electrons by an incident electron. (05 Aug 1998) |

| receiver operating characteristic | A plot of the sensitivity of a diagnostic test as a function of non-specificity (one minus the specificity). The ROC curve indicates the intrinsic properties of a test's diagnostic performance and can be used to compare the relative merits of competing procedures. (05 Mar 2000) |
|---|---|
| receiver operating characteristic curve | A plot of true positive versus false positive results, usually in a trial of a diagnostic test. A graphical means of assessing the ability of a screening test to discriminate between healthy and diseased persons. Synonym: ROC curve. (05 Mar 2000) |
| characteristic | Synonym: character. 2. Typical or distinctive of a particular disorder. (05 Mar 2000) |
| characteristic curve | Sensitometric curve of radiographic film, a plot of the film density versus the logarithm of the relative exposure. Synonym: H and D curve, Hunter and Driffield curve. (05 Mar 2000) |
| 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) |
