| depth 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) |

| attenuation 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) |
|---|---|
| gene dosage compensation | The putative mechanism that adjusts the X-linked phenotypes of males and females to compensate for the haploid state in males and the diploid state in females. It is now largely ascribed to lyonization which compensates the mean of the dose but not its variance, which is greater in females. (05 Mar 2000) |
| compensation | In interference microscopy, compensation for the phase difference introduced by the object, measured by introducing a quarter wavelength plate and rotating the analyser: the angle of rotation is proportional to the optical path difference. (18 Nov 1997) |
| compensation neurosis | The development of symptoms of neurosis believed to be motivated by the desire for, and hope of, monetary or interpersonal gain. (05 Mar 2000) |
| workers' compensation | Insurance coverage providing compensation and medical benefits to individuals because of work-connected injuries or disease. (12 Dec 1998) |
| dosage compensation | <genetics> A genetic regulatory mechanism which operates to equalise the phenotypic expression of characteristics determined by genes on the x chromosome so that they are equally expressed in the xy male and the xx female. (12 Dec 1998) |
| 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-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) |
| anaesthetic depth | The degree of central nervous system depression produced by a general anaesthetic agent; a function of potency of the anaesthetic and the concentration in which it is administered. (05 Mar 2000) |
| depth | Distance from the surface downward. (05 Mar 2000) |
| depth dose | The dose of radiation at a distance beneath the surface, including secondary radiation or scatter, in proportion to the dose at the surface. (05 Mar 2000) |
| depth of field | <microscopy> The depth or thickness of the object space that is simultaneously in acceptable focus. The distance between the closest and farthest objects in focus within a scene as viewed by a lens at a particular focus and with given settings. The depth of field varies with the focal length of the lens and its f-stop setting or numerical aperture, and the wavelength of light. Depth of fields only a small fraction of a micrometre can be achieved at 546 nm with microscope lenses of N.A. Greater than 0.9. (05 Aug 1998) |
| depth of focus | <microscopy> The depth or thickness of the image space that is simultaneously in acceptable focus. The range of distances between a lens and image plane (target in the video pickup device) for which the image formed by the lens at a given setting is clearly focused. With a high-numerical aperture microscope objective, the depth of field is very shallow, but the depth of focus can be quite deep and reach several millimetres. (05 Aug 1998) |
| depth perception | Perception of three-dimensionality. (12 Dec 1998) |
| depth psychology | The psychology of the unconscious, especially in contrast with older (19th century) academic psychology dealing only with conscious mentation; sometimes used synonymously with psychoanalysis. (05 Mar 2000) |
