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.


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.
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. The light which has no colour or is achromatic such as in radiographic plates has only one descriptor, which is its brightness or grey value. This light has a saturation of 0% and it contains only white light. ...
