A diagnostic technique using heat waves to detect breast cancer in its early developmental stages.
A technique, used especially in screening for breast cancer, where part of the body is photographed using infrared rays which record the heat given off by the skin and show variations in the blood circulating beneath the skin.
Technique for sensing (by means of an infrared detector) and recording the heat produced by different parts of the body; it is used to study blood flow and detect tumors (which may show as hot spots), especially those of the breast (mammothermography). Its validity as a medical test has been seriously questioned in medical literature over recent years.
Measurement of temperature variations in soft tissues; a useful technique for detecting various abnormalities.
An imaging technique employing the detection of heat emitted from the body. Disease states that manifest increased or decreased blood flow present thermographic patterns that can be distinguished from those of normal subjects.
A technique for measuring and recording the heat produced by different parts of the body, by using photographic film sensitive to infrared radiation. The picture produced is called a thermogram. The heat radiated from the body varies in different parts according to the flow of blood through the vessels; thus areas of poor circulation produce less heat. On the other hand a tumor with an abnormally increased blood supply may be revealed on the thermogram as a ‘hot spot. The technique has been used in the diagnosis of tumors of the breast (mammothermography).
A diagnostic technique which detects and records heat in tissues. Tissues in different states of chemical activity have different temperatures, and mapping the pattern of temperatures is used, for example, in efforts to find tumors in breasts.
A method of detecting the amount of heat produced by different parts of the body. This is done with an infra-red sensitive photographic film. High blood flow in an area shows up as a heat zone and thus tumours such as breast cancer can be identified. The process records such changes in temperature in a record known as a thermogram. Unfortunately, such hot areas of skin are caused by a number of other conditions; this is therefore a diagnostic method that can be used only as a rough screening procedure.
The detection of the heat present in body parts, such as blood vessels, muscles and tendons, or skin. Thermography has a wide range of uses. It has been employed in the study of arterial blood flow, the cause of lameness in animals, and breast cancer.
Thermal imaging, a form of photography, utilizes long-wavelength radiation emitted by objects within a temperature range spanning from -170°F to over 300°F. This technique is commonly referred to as thermal photography or infrared photography.
A method through which temperature patterns across the skin’s surface are captured in the form of an image. Thermography offers insights into the existence of illnesses and irregularities that influence the skin’s temperature, such as circulatory issues, inflammation, and tumors. There are two variants of thermography. In the first, a camera or scanner detects naturally emitted infrared radiation from the skin. In the second, temperature-sensitive liquid crystal sheets are applied to the skin, changing color in response to temperature fluctuations.
