- That is why having a technique chart on the wall can help to choose the right technical factors to get the X-ray image done right the first time. These x-ray technique charts are good for any body part. It also helps technologists abide by one of their fundamental underlying directives, ALARA. This stands for As Low As Reasonably Achievable.

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.
Oct 24, 2012 · Instead having an easy to read exposure chart make life much easier! Most are based on selecting the body part that you want to radiograph and then the thickness of that body part. The reason for looking at these two things is simple.
Oct 3, 2022 · Functional technique charts (including fixed-kVp and high-kVp charts) are used to produce radiographs depending on the type of study (body part) and other factors, such as the x-ray machine itself. Anatomically Programmed Radiography plays a role in automatically selecting kVp and mAs depending on the technologist’s selection of an anatomic part.

The milliamperage, or mA, is a measure of current passing through the x-ray tube at the time of the exposure. The milliamperage is set by the radiographer on the control panel and this setting determines the quantity of x-rays produced during the exposure. The mA setting determines how hot the filament of the x-ray tube gets.
Feb 27, 2016 · Radiographic Exposure Technique. • Explain the relationship between milliamperage and exposure time with radiation production and image receptor exposure. • Calculate changes in milliamperage and exposure time to change or maintain exposure to the image receptor.
Mar 6, 2016 · Tools are available to assist the radiographer in selecting appropriate exposure techniques: automatic exposure control (AEC) devices, anatomically programmed radiography, and exposure technique charts.
Nov 3, 2023 · The advantages of CT over x-ray radiography are that it enables a three-dimensional insight into the body, giving a more accurate presentation of the area of interest. There are many CT techniques, such as single slice CT (SSCT), spiral CT and multi slice CT (MSCT).
