| total quality management | The application of industrial management practice to systematically maintain and improve organization-wide performance. Effectiveness and success are determined and assessed by quantitative quality measures. (12 Dec 1998) |
|---|---|
| total refractory period | The absolute refractory period plus the relative refractory period. (05 Mar 2000) |
| total sclerectasia | Uniform stretching of the entire sclera, typically seen in buphthalmos. (05 Mar 2000) |
| total spinal anaesthesia | Spinal anaesthesia extensive enough to produce loss of sensation in all extracranial sensory roots. (05 Mar 2000) |
| total suspended particulates | The quantity of solid particles in a gas or exhaust stream. Any finely divided material (solid or liquid) that is airborne with a diameter smaller than a few hundred micrometres. (05 Dec 1998) |
| total suspended solids | The organic and inorganic material left on a standard glass fibre filter (0.45 micron) after a water sample is filtered through it. (09 Oct 1997) |
| total synechia | Adhesion of the entire surface of the iris to the lens capsule. (05 Mar 2000) |
| total transfusion | Removal of most of a patient's blood followed by introduction of an equal amount from donors. Synonym: exsanguination transfusion, substitution transfusion, total transfusion. (05 Mar 2000) |
| absorbed dose | The amount of energy absorbed per unit mass of irradiated material at the target site; in radiation therapy, the former unit for absorbed dose is the rad; the current (S.I.) unit is the gray. (05 Mar 2000) |
| air dose | The radiation dose, expressed in roentgens, delivered at a point in free air. Synonym: air dose. (05 Mar 2000) |
| bone marrow dose | The cumulative dose to the blood-forming organ from therapeutic or nuclear fallout irradiation; the presumed leukemogenic dose. (05 Mar 2000) |
| booster dose | A dose given at some time after an initial dose to enhance the effect, said usually of antigens for the production of antibodies. (05 Mar 2000) |
| breast dose in mammography | <radiology> 180 mrad / view -- mid-breast dose, guideline: less than 1 rad for 2-view exam (12 Dec 1998) |
| maintenance dose | In chemotherapy, systematic dosage at a level that maintains protection against exacerbation. (05 Mar 2000) |
| genetically significant dose | <physics, radiobiology> The genetically significant dose is that which, if received by every member of the population, would be expected to produce the same genetic injury to the population as do the actual doses received by the individuals irradiated. Thus, the genetically significant dose is the dose equivalent to the gonads weighted for the age and sex distribution in those members of the irradiated population expected to have offspring. The genetically significant dose is expressed in sieverts (or rem). Acronym: GSD (06 Aug 1998) |
