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.

Customer Testimonials

What our users say...

Vision RT has also improved the setup for other sites such as extremity lesions and many other disease sites. You’re going to keep hearing this over and over again – it is improving our accuracy and throughput.

Nancy Wiggers MD, Radiation Oncologist, Department Chair, Northside Hospital*

I have to say that this is really the missing piece that we felt we needed in order to move fully to frameless, image-guided radiation … we are very comfortable treating multiple metastases, feeling that we are able to give treatment as planned.

Private: Josh Yamada MD FRCPC, Memorial Sloan Kettering Cancer Center*

Extremities – these can be so difficult for a therapist to set up. [AlignRT] just makes life so much easier. You can make sure that the bend of the arm or the bend of the knee is more accurate.
