It can be difficult to deliver radiation safely and efficiently to tumors in the limbs, and challenging to position accurately over multiple treatments, due to the range of possible movement. However, as with all radiation therapy treatments, accurate patient positioning is key to ensuring the actual patient dose matches that of the plan. AlignRT® can help reduce the need for immobilization and increase accuracy when treating extremities.
A study from Massachusetts General Hospital¹ using AlignRT on sarcoma patients concluded that “Surface imaging may reduce setup errors and is a feasible technique for daily image guidance.”
With AlignRT, you can position the limb in the same way as it was positioned during the CT scan, aligning and tracking in all six degrees of freedom.
