ABSTRACT:
A method for quantitatively evaluating the quality of radiographic films is disclosed. The method provides for digitizing a radiographic image to form a digital image made up of a plurality of pixels. The individual pixels of the digitized image are assigned grey level values. These grey level values are summed to form a global histogram representing all of the pixels of the digital image. The histogram is subsequently binned and subdivided to form first and second binned histograms. A series of rules is applied to these histograms to evaluate whether the radiographic film is clinically acceptable for use in making a diagnosis.
