Measuring a person's temperature gives basic information about their health.
NASA has developed an
Infrared Ear Thermometer which can record a patient's temperature
in two seconds.
Medical infrared technology is used for the non-invasive analysis of body
tissues and fluids. Medical information about injuries such as carpal tunnel
syndrome, back and sports injuries, and diseases such as arthritis and
breast cancer can be gained by studying where heat is distributed in the body.
Infrared imaging is used to determine the depth of burns and in the analysis
of blood flow and muscle performance.
Many of these methods are also used in
veterinary medicine.
Infrared remote sensing is useful in monitoring diseases that are
spread by mosquitos, whose presence is associated with certain land features
or vegetation.
NASA is even working on a project which will allow surgeons to perform
operations in the dark.
