A radiograph of a lateral cranium reveals that the mentum of the mandible was cut off from the bottom of the radiograph. A 24 × 30-cm (10 × 12-inch) IR was used, and it was placed landscape. What must be altered if a repeat exposure is performed?

A)Center the CR at the EAM.
B)Increase SID to reduce magnification.
C)Place the 24 × 30-cm (10 × 12-inch) IR lengthwise.
D)None of the above; all of the critical structures were demonstrated.
