BASIC PROCEDURES

Radiographs are never taken unless requested or authorized by a dental officer. When a patient reports to the dental radiographic service, the desired radiographs are determined, appropriate information is recorded in the logbook (depending upon local policy), and certain basic procedures are performed.

(2) Drape the patient with the lead apron and attach the cervical collar.

(3) Position the film packet.

(4) Align the x-ray tube.
