The next phase involves the radiographer assessing the patient prior to selecting the most appropriate imaging equipment and positioning methods for the projections that will best answer the clinical query. Essentially the radiographic procedure involves the selection of exposure factors and the accurate positioning of the patient's body in relation to the x-ray tube and the imaging device.
Today the imaging device will either be a conventional x-ray cassette and x-ray film which will be developed photographically or a digital plate which will be computer processed. Prior to sending the radiographs or images on for reporting by the radiologist, radiographers must evaluate their radiographs or images in terms of image quality, radiographic positioning and the clinical question. This means radiographers need a high level of knowledge about the science of image formation, radiographic anatomy and pathophysiology.
