Infrared tympanic thermography is a new method of measuring body temperature. We compared body temperature measured in the rectum and in the ear in 25 patients. The results reveal a difference of average +/- 0.3 degree C. We also measured the time used to perform the above procedures. We found that the preparation and completion procedures took on average two minutes and 50 seconds when the body temperature was measured in the rectum. Taking the temperature in the ear took on average 42 seconds. We found that this new method was an accurate and quick method to measure body temperature.

UI	MeSH Term	Description	Entries
D007259	Infrared Rays	That portion of the electromagnetic spectrum usually sensed as heat. Infrared wavelengths are longer than those of visible light, extending into the microwave frequencies. They are used therapeutically as heat, and also to warm food in restaurants.	Heat Waves,Heat Wave,Infrared Ray,Ray, Infrared,Rays, Infrared,Wave, Heat,Waves, Heat
D012007	Rectum	The distal segment of the LARGE INTESTINE, between the SIGMOID COLON and the ANAL CANAL.	Rectums
D001831	Body Temperature	The measure of the level of heat of a human or animal.	Organ Temperature,Body Temperatures,Organ Temperatures,Temperature, Body,Temperature, Organ,Temperatures, Body,Temperatures, Organ

D013817	Thermography	Imaging the temperatures in a material, or in the body or an organ. Imaging is based on self-emanating infrared radiation (HEAT WAVES), or on changes in properties of the material or tissue that vary with temperature, such as ELASTICITY; MAGNETIC FIELD; or LUMINESCENCE.

D013821	Thermometers	Measuring instruments for determining the temperature of matter. Most thermometers used in the field of medicine are designed for measuring body temperature or for use in the clinical laboratory. (From UMDNS, 1999)	Thermometer
D014432	Tympanic Membrane	An oval semitransparent membrane separating the external EAR CANAL from the tympanic cavity (EAR, MIDDLE). It contains three layers: the skin of the external ear canal; the core of radially and circularly arranged collagen fibers; and the MUCOSA of the middle ear.
