- The chart contains all the different parameters or technical factors that the radiographer needs to capture a diagnostic image. Having a chart containing established technical parameters prevents technologists from the need to stop and calculate all of the components needed for a high-quality image by hand with each exposure.

Jun 12, 2019 · Watch on. What is the purpose of a radiography techniques chart? 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.
A reliable, user-friendly technique chart is important for obtaining consistent radiographic density and contrast. When film, cassette, or machine type is changed, technique charts need to be changed as well.
To develop a technique chart for conventional film-screen radiography, use the following guidelines: taken into account when assessing radi-ographs for diagnostic quality: optimal density and contrast, proper positioning, and minimal patient motion.
