thermography

n. printing process in which a plastic dust is applied to wet ink and then heated to create the appearance of embossing (Printing); technique for measuring skin temperature (Medicine)

This article is about the infrared imaging technique. For the printing technique called thermography, see thermographic printing Thermography, thermal imaging, or thermal video, is a type of infrared imaging. Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 900–14,000  nanometers or 0.9–14 µm) and produce images of that radiation. Since infrared radiation is emitted by all objects based on their temperatures, according to the black body radiation law, thermography makes it possible to "see" one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature, therefore thermography allows one to see variations in temperature (hence the name). When viewed by thermographic camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become easily visible against the environment, day or night. As a result, thermography's extensive use can historically be ascribed to the military and security services.

Noun
1. diagnostic technique using a thermograph to record the heat produced by different parts of the body; used to study blood flow and to detect tumors
(hypernym) diagnostic procedure, diagnostic technique
(hyponym) mammothermography

In medicine, a procedure in which a heat-sensing infrared camera is used to record the surface heat produced by different parts of the body. Abnormal tissue growth can cause temperature changes, which may show up on the thermogram. Thermography may be used to diagnose breast cancer and other tumors.
