| Shielding | gonads; and the thyroid gland by using a thyroid collar as the thyroid gland is exposed to the primary beam. (check your department's policy guidelines) |
| Respiration | suspended |
| Positioning | - Place the patient in an upright body position, either seated or standing, before a vertical grid device
- Midpoint of IR should be at the same level of AC joints
- Ensure weight of body is equally distributed on the feet to avoid rotation
- Make two exposures: one with patient WITHOUT weights attached to wrists, and second: patient WITH equal weights (5 - 10 lbs) affixed to each wrist by a band or strap.
- AVOID having the patient hold the weights in each hand as this reduces the possibility of demonstrating a small AC separation
