thermography

 [ther-mog´rah-fe]
a technique wherein an infrared camera photographically portrays the body's surface temperature, based on self-emanating infrared radiations; used as a diagnostic aid in the detection of breast tumors and the assessment of rheumatic joints; also used in the study of pain. adj., thermograph´ic.

ther·mog·ra·phy

(ther-mog'ră-fē),
The technique for making a thermogram.

thermography

(thər-mŏg′rə-fē)
n. pl. thermogra·phies
1. A process for producing raised lettering, as on stationery or calling cards, by application of a powder that is fused by heat to the fresh ink.
2. A technique in which an infrared camera is used to measure temperature variations on the surface of a structure or body part, used diagnostically to produce images that reveal sites of abnormal tissue growth.

ther′mo·graph′ic (-mə-grăf′ĭk) adj.
ther′mo·graph′i·cal·ly adv.

thermography

Imaging An abandoned method for diagnosing breast CA based on an ↑ warmth of skin overlying malignancy; heat is a relatively nonspecific finding that also occurs in mastitis; the technique was abandoned due to the unacceptably high rates of false positivity and false negativity; it has no role in breast CA diagnostics. Cf Mammography, Xeroradiography.

ther·mog·ra·phy

(thĕr-mog'ră-fē)
The technique for making a thermogram.

thermography

A scanning technique in which temperature differences on the surface of the skin are represented as an image or as colour differences. Thermography readily demonstrates areas of inflammation and variations in blood supply, but has not proved particularly useful as an aid to diagnosis.

ther·mog·ra·phy

(thĕr-mog'ră-fē)
The technique for making a thermogram.

The radiation that results directly from the camera is called parasitic radiation and can cause inaccuracies in camera measurement output, especially with thermographically calibrated cameras.
