An acceptable-looking image with an indicator change

A digital radiography service notices that several images look acceptably bright after processing, but acquisition indicators have drifted upward compared with the agreed target for comparable examinations. A team member proposes ignoring the change because radiologists have not complained about darkness. Another proposes repeating every image at a lower setting without checking whether the first examination already answered the clinical question. The service has not yet assessed patient size, technique selection, processing, calibration or changes in workflow. The reviewer must distinguish a useful investigation from an unnecessary repeat policy. This case supplies no universal target exposure value and does not assume that an indicator is an exact direct patient organ-dose measurement.
