Non-contact thermography, thermographic imaging, or medical thermology is the field of thermography that uses infrared images of the ... body that have abnormal heat ...
"Mammography (taking X-ray pictures of the breasts) is the most effective breast cancer screening method and the only method proven to increase the chance of survival through earlier detection."
Thermogram of a traditional building in the background and a "passive house" in the foregroundInfrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science.
When compared with other classical NDT techniques such as ultrasonic or radiographic testing, thermographic inspection is safe, nonintrusive, and usually noncontact, allowing the detection of relatively shallow subsurface defects (a few millimeters in depth) under large surfaces (typically covering an area of 30 by 30 cm (12 by 12 in) at once, although inspection of larger surfaces is possible ...
Inset shows false color infrared thermograph of a roof on a sunny day; the white surfaces (colored blue in the thermograph) have been coated with an elastomer to reduce solar loading and have a surface temperature of approximately 60 °F (16 °C); the gray surfaces (colored red/white in the thermogram) are a standard asphalt (bitumen) coating and have a surface temperature of approximately 160 ...
Dynamic angiothermography utilizes thermal imaging, but with important differences from the older kind of thermography, which impact detection performance. First, the probes are much improved over the previous liquid crystal plates; they include better spatial resolution, contrastive performance, and the image is formed more quickly.
In the simplest case, the response is evident from a thermogram directly. However, it is necessary to use advanced analysis techniques in most cases. The most common methods include Lock-In, Pulse or Transient (Step thermography) evaluation techniques, with continuous excitation used in some cases: [4] Lock-In thermography (periodic excitation ...
Typically the flyover of the right of way is recorded by video, which may have some image filtering, such as thermal imaging. Larger spills will typically be identified by a "sheen" in wetland or an area of dead vegetation around the release location. Flyovers are typically scheduled and not recommended as a primary leak-detection method.
