Sarah,

We’ve used on many extremities and SGRT has been extremely helpful. Depending on what part of extremity you are treating, you could use vac-loc but the key is to help support and not to build up too much on sides. Leave plenty of room on both sides of extremity in order to draw sufficient ROI so SGRT system can give accurate reading for the movements needed.

We’ve also done without vac-loc but would depend on what part of arm you are treating. For example: We treated a forearm and had the patient lay in prone position with arm stretched out. We immobilized the hand and wrist and had the forearm exposed so we could get a great ROI for setup and for monitoring during treatment.

When you use the SGRT system for initial setup on an extremity you will see how sensitive to movement the system actually is. It is excellent at detecting the difference in roll and pitch from initial CT (more than marks could ever detect).

Hope this helps. Let me know which area you are treating and I can give you more specific answers!
