CLINICAL MEDICINE

Detailed explanation-1: -When the mA or exposure time increases, the number of x-ray photons generated at the anode increases linearly without increasing beam energy. The result will be a higher number of photons reaching the receptor, and this leads to an overall increase in the density of the radiographic image (Figure 2).

Detailed explanation-2: -Exposure to high doses of radiation over a short period of time can cause radiation sickness (sometimes called radiation poisoning or acute radiation syndrome) and even death.

Detailed explanation-3: -An exposure time of 10 milliseconds (. 010) or less is recommended for most routine x-rays. Generally, the shortest exposure time in combination with the highest mA should be used for exposures to reduce motion artifacts. mAs stands for milli-ampere-second.

Detailed explanation-4: -The longer the exposure time, the more photons the detector will receive, resulting in increased pixel intensity and a “brighter” image. Ideally, you want to use an exposure time that takes advantage of the full dynamic range of the camera you are using.
