Breath cancer analysis. Thermographic footage of a man breathing towards a dog's nose as part of a test for cancer. A thermogram shows variation in temperature on the surface of an object, measured by the long-wave infrared radiation it emits. The temperature scale is colour-coded from black (cold) through dark blue, light blue, green and yellow to red and white (hottest). This thermogram footage shows that exhaled air is warm, but cools quickly. Dogs have an extremely sensitive sense of smell, and can be trained to detect different types of chemicals, including those produced in the breath in some forms of cancer. | |
