The radiographer has an ethical responsibility to the patient to produce the highest diagnostic quality radiographs, in return for the patient’s consent to undergo the radiographic examination. Less-than-ideal radiographic images diminish the usefulness of the radiograph. When the error is significant, a radiograph will have to be retaken. In addition to increasing the patient’s radiation exposure, retake radiographs require additional patient consent and may reduce the patient’s confidence in the operator and in the practice. No .
