What does it mean to be under the direct supervision of a qualified radiologic technologist?

For the performance of a mammography examination, direct supervision means that the supervisor is present to observe and correct, as needed, the performance of the trainee. This requires that the supervisor be in the examination room itself during the time the examination is being conducted. The goal of direct supervision is to provide reasonable assurance that any mistakes made by the trainee are corrected before the patient is irradiated or harm is done to the patient.
