| subtraction technique | Combination or superimposition of two images for demonstrating differences between them (e.g., radiograph with contrast vs. One without, radionuclide images using different radionuclides, radiograph vs. Radionuclide image) and in the preparation of audiovisual materials (e.g., offsetting identical images, colouring of vessels in angiograms).

| delphi technique | An iterative questionnaire designed to measure consensus among individual responses. In the classic delphi approach, there is no interaction between responder and interviewer. (12 Dec 1998) |
| dental casting technique | <dentistry> The process of producing a form or impression made of metal or plaster using a mold. (12 Dec 1998) |
| dental impression technique | Procedure of producing an imprint or negative likeness of the teeth and/or edentulous areas. Impressions are made in plastic material which becomes hardened or set while in contact with the tissue. They are later filled with plaster of paris or artificial stone to produce a facsimile of the oral structures present. Impressions may be made of a full complement of teeth, of areas where some teeth have been removed, or in a mouth from which all teeth have been extracted. (12 Dec 1998) |
| direct technique | In dentistry, an inlay technique in which the wax pattern is made directly in the prepared cavity in the tooth. Synonym: direct technique. (05 Mar 2000) |
| dye dilution technique | Method for assessing flow through a system by injection of a known quantity of dye into the system and monitoring its concentration over time at a specific point in the system. (12 Dec 1998) |
| ilizarov technique | A bone fixation technique using an external fixator (fixators, external) for lengthening limbs, correcting pseudarthroses and other deformities, and assisting the healing of otherwise hopeless traumatic or pathological fractures and infections, such as chronic osteomyelitis. The method was devised by the russian orthopedic surgeon gavriil abramovich ilizarov (1921-1992). (12 Dec 1998) |
| immunoperoxidase technique | An immunologic test that utilises antibodies chemically conjugated to the enzyme peroxidase. (05 Mar 2000) |
| indirect technique | indirect method for making inlays |
| Ouchterlony technique | A technique in which both reaction partners (antigen and antibody) are allowed to diffuse to each other in a gel in a precipitation reaction. (05 Mar 2000) |
| technique | The manner of performance, or the details, of any surgical operation, experiment, or mechanical act. See: method, operation, procedure. Synonym: technic. Origin: Fr., fr. G. Technikos, relating to techne, art, skill (05 Mar 2000) |
| enzyme-multiplied immunoassay technique | A type of immunoassay in which the ligand is labelled with an enzyme, and the enzyme-ligand-antibody complex is enzymatically inactive, allowing quantitation of unlabelled ligand. The test uses antibodies that react only with the particular drug for which the sample is being tested. The antibodies attach themselves to the drug if it is present in the sample. It is not designed to measure amounts of the drug present, only to detect its presence or absence. It is used predominantly, but not exclusively, for the detection of drugs of abuse in the urine. See: competitive binding assay, enzyme-linked immunosorbent assay. (05 Mar 2000) |
| Jerne technique | A technique for measuring immunocompetence by quantitating the number of splenic antibody-forming cells found in a mouse that has been sensitised to sheep erythrocytes. The number of plaques formed correlates with the number of splenic antibody-forming cells. (05 Mar 2000) |
| Judkins technique | A method of selective coronary artery catheterization utilizing the standard Seldinger technique through a percutaneous femoral artery puncture. (05 Mar 2000) |
| kleinschmidt monolayer technique | <technique> A method for preparing DNA for study under an electron microscope, the DNA molecules are spread as a thin, positively charged protein film onwater. The film is then transferred to a copper viewing grid andplaced under the microscope. (17 Dec 1997) |
