The patient is instructed to remain in a relaxed, neutral posture while sitting upright and having the hard palette level with the floor. 7-3), and it will be used as a reference point to help the doctor locate the patient’s Atlas transverse process contact. This landmark point on the radiograph will be transferred to the patient’s Listing card (see Chapter 7, Fig. A piece of lead shot will then be taped to the anterior/inferior corner of the patient’s earlobe closest to the grid cabinet ( Fig. 3-1) be placed that will cover the patient’s chest/breast region, the lap, and the upper legs. It is recommended that a half lead apron ( Fig. The patient is then asked to remove all Radiopaque articles (e.g., hairpins, jewelry, dental plates) that will be located in the region being exposed.
