| time compensation gain | 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) |

| time constant | That part of a circuit that determines the time interval over which the rate of electrical events will be averaged; in pulmonary physiology, the factors determining rate of flow in the airways. (05 Mar 2000) |
| time factors | Elements of limited time intervals, contributing to particular results or situations. (12 Dec 1998) |
| time-gain 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) |
| time lapse | <technique> Technique applied to speed up the action in a film or videotape sequence. In filming by taking a frame every few seconds and projecting at conventional speed (16 or 24 frames per second), the movements of cells can be greatly speeded up and then become conspicuous. With videotape, the recording is made at slow tape speed and replayed at full speed. The opposite of slow motion. (28 May 1998) |
| time-lapse microscopy | Microscopy in which the same object (e.g., a cell) is photographed at regular time intervals over several hours. (05 Mar 2000) |
| time management | Planning and control of time to improve efficiency and effectiveness. (12 Dec 1998) |
| time marker | An instrument that marks the time, usually in seconds or fractions of seconds, on a kymograph record in physiologic experiments. (05 Mar 2000) |
| time of flight | The time for a photon created by annihilation of a positron-electron pair to reach a detector; since annihilation photons are created in pairs and travel in opposite directions at about 3 × 1010 cm/sec, measurement of the difference in arrival time at detectors with sub-nanosecond resolution allows calculation of the location of the event; the basic physics of positron emission tomography. (05 Mar 2000) |
| time perception | The ability to estimate periods of time lapsed or duration of time. (12 Dec 1998) |
| time sense | The faculty by which the passage of time is appreciated. (05 Mar 2000) |
| time-varied gain | 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) |
| time-varied gain control | 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) |
| tissue thromboplastin inhibition time | A test used to identify lupus anticoagulant; the thromboplastin source used in the prothrombin test is diluted to increase sensitivity to inhibitors. (05 Mar 2000) |
| energy confinement time | <radiobiology> Characteristic time in which 1/e (or sometimes 1/2) of a system's energy is lost to its surroundings. In a plasma device, the energy loss time (or the energy confinement time) is one of three critical parameters determining whether enough fusion will occur to sustain a reaction. See: Lawson criterion. (09 Oct 1997) |
