Billing: 1. CT Head without
2. 3D CT Head if done
Setup: 1. Patient Supine, AP and lateral scouts, no gantry angle
3. Remove all metallic and high-density objects from the scanning area
3. Patient Positioning: Tilt the patient’s head so that a line connecting the lateral
canthus of the eye and the EAC is perpendicular to the CT tabletop (see below).

2. 3D Exam: Please perform three 360 0 rotations at 10 0 intervals as follows
a. From a right lateral view = rotate the head horizontally for 360 0
b. From an AP view = rotate vertically for 360 0
c. From a Water’s type view = rotate horizontally for 360 0 (note: to get a Water’s type
projection rotate the patient’s nose upward about 20 0 )
