Jun 12, 2019 · To list the exam parameters needed to obtain an optimal x-ray image, including kVp, mAs, SID, body part and patient size. This chart is vital in the medical imaging field. you can use it to image animals in a veterinary setting and humans in a medical setting.
Two exposure factors directly control the quantity of x-rays produced and therefore the image receptor exposure. These are milliamperage and exposure time. The milliamperage, or mA, is a measure of current passing through the x-ray tube at the time of the exposure.
Oct 17, 2022 · Signal-to-Noise Ratio. The signal-to-noise ratio (SNR) is an important metric that combines the effects of contrast, resolution, and noise. The higher the signal and lower the noise, the better the image quality. Images with high SNR allow the recognition of smaller and lower contrast structures.
