Document Summary
In radiology departments such as qm related activity includes reject repeat image analysis. What is the purpose: films that are not diagnostic films, cannot provide information, systematically catalog images that do not end up in the patients folder, help use know why these images are not noticeable. Process of repeat analysis: take little time. Id conditions easily corrected: collimation off or artifact based on equipment problems, goal: reduce patient dose, costs, radiographer time and effort. Is a measure of film waste: not as significant in digital imaging, waste film include repeated diagnostic images as well as test images, test images: grid alignment etc, the reject rate is given by. Equation: (#repeat films + # waste films/total # of films) x 100: total films used = repeat +waste + diagnostic films, every film used in the department, how many ended up in the.
