| solid-state detector | A detector that uses a crystalline scintillating material rather than an ionization chamber to detect or measure radiation. (05 Mar 2000) |
|---|---|
| detector | One who, or that which, detects; a detecter. "A deathbed's detector of the heart." (Young) Bank-note detector, a publication containing a description of genuine and counterfeit bank notes, designed to enable persons to discriminate between them. Detector lk. See Lock. Origin: L, a revealer. Source: Websters Dictionary (01 Mar 1998) |
| detector coil | A coil used in magnetic resonance imaging as an antenna to record radiofrequency emissions of stimulated nuclei, e.g., body coil, head coil. (05 Mar 2000) |
| flame ionisation detector | <apparatus> A piece of equipment used in gas chromatography that uses a flame to decompose the neutral solute molecules into charged particles, then measures any changes in conductivity. (09 Oct 1997) |
| lie detector | 1. An instrument for multiplying copies of a writing; a manifold writer; a copying machine. 2. In bibliography, a collection of different works, either by one or several authors. Origin: Gr. Writing much; much, many + to write: cf. F. Polygraphe. Source: Websters Dictionary (01 Mar 1998) |
| absolute intensity threshold acuity | The minimal light that can be seen. (05 Mar 2000) |
| absolute threshold | The lowest limit of any perception whatever. Compare: differential threshold. Synonym: stimulus threshold. (05 Mar 2000) |
| achromatic threshold | Threshold of visual sensation, the minimal light intensity evoking a visual sensation. Synonym: achromatic threshold, minimum light threshold. (05 Mar 2000) |
| anaerobic threshold | The oxygen consumption level above which aerobic energy production is supplemented by anaerobic mechanisms during exercise, resulting in a sustained increase in lactate concentration and metabolic acidosis. The anaerobic threshold is affected by factors that modify oxygen delivery to the tissues; it is low in patients with heart disease. Methods of measurement include direct measure of lactate concentration, direct measurement of bicarbonate concentration, and gas exchange measurements. (12 Dec 1998) |
| auditory threshold | The audibility limit of discriminating sound intensity and pitch. (12 Dec 1998) |
| brightness difference threshold | The smallest difference that can be perceived as a difference in brightness. Synonym: light difference. (05 Mar 2000) |
| pain threshold | Amount of stimulation required before the sensation of pain is experienced. (12 Dec 1998) |
| galvanic threshold | The minimal strength of an electrical stimulus of indefinite duration that is able to cause excitation of a tissue, e.g., muscle or nerve. See: chronaxie. Synonym: galvanic threshold. Origin: rheo-+ G. Basis, a base (05 Mar 2000) |
| relational threshold | The smallest degree of difference between two stimuli that permits them to be perceived as different. (05 Mar 2000) |
| visual threshold | Threshold of visual sensation, the minimal light intensity evoking a visual sensation. Synonym: achromatic threshold, minimum light threshold. (05 Mar 2000) |
