Essay example - Diganostic Radiography
Pages 9 (2259 words)
This study could be repeated with a use of a larger x-ray plate to accommodate the size of the patient. During the investigation, it is also imperative that the patient does not move. The intensity of the radiation must be reduced, and the focus must be on the ureteropelvic junction since in 5 minutes…
Extract of sample
Evaluation of radiological images is the key to an accurate medical diagnosis and hence bears significant importance in radiography. When a radiographer is required to image a particular organ, there must be certain procedures followed which would ensure the quality of the image. Otherwise, the quality of the image may be compromised in such a fashion that diagnosis from the image plate becomes either erroneous or impossible (Barten, 1999). Since evaluation of the radiographic image depends on visual appreciation of the apparent image on the radiographic plate, a good quality image would need to fulfill certain physical criteria for an accurate diagnostic yield, although some parts of it are contributed to by technical soundness of the process of imaging and some are contributed to by the factors essentially related to the patient. Whatever may be the reason, a poor image quality compromises the diagnostic yield, and in some cases, a reading or a diagnosis is not possible, where the radiographic plate needs to be rejected, and re-examination is mandated (Beutel et al., 2000). In this assignment, an evaluatory report of a radiographic image will be presented with a critical discussion about the reasons for it being discarded and a re-examination being recommended.
Criteria for Image Evaluation
While evaluating an image, it must be borne in mind that evaluation of image is dependent on human vision as related to the examiner. Since radiographic images are essentially black and white, it is to be considered that ideal white light has flat spectrum in which all wavelengths of lights are present. In practice white light sources approximates this property. ...
