The basic concepts of digital x-ray detectors are covered including the important concepts. Digital detectors are separated into small individual components termed detector elements (DELs), and the size of individual DELs is referred to as the pixel pitch.
What is TFT xray?
The TFT arrays are as large as the area that is to be imaged. The function of the TFTs is to amplify the electrical signal produced by the conversion of light from the photodiodes, and to store it in the form of an electrical charge. When a high potential difference is applied to the TFT, it releases the charge.Nov 14, 2018
What is quantum mottle caused by?
Quantum mottle is an inescapable artifact of radiologic imaging. It is caused by constraints in the number of x-raysx-raysThe roentgen or röntgen (/ˈrɜːntɡən/; symbol R) is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air (statcoulomb per kilogram).https://en.wikipedia.org › wiki › Roentgen_(unit)Roentgen (unit) - Wikipedia at a specific strength passing through tissues of different densities and striking the film or display screen, which has an inherent speed.
