New Proton Therapy Equipment Enables More Tumors to be Treated

JACKSONVILLE, Fla. Feb. 23 /PRNewswire/ -- An advance in the way protons are delivered at the University of Florida Proton Therapy Institute enables physicians to treat tumors that are deeper in the body, tumors that are very large and tumors that are situated closer to vital organs.

Called uniform scanning, the new device moves a single beam of protons in a sweeping or "scanning" motion, enabling the beam to reach deeper into the body and to cover a wider treatment area than the more commonly used scattering method. Until now the proton beam was "scattered" and flattened using round filters that limited how deep and how wide protons could travel into the body.

Proton therapy will now be a possible treatment option for prostate cancer patients with a hip circumference of more than 50 inches and for sarcoma patients with tumors larger than 9.4 inches. Uniform scanning also means significant medical advantages for patients with tumors in the head and neck, brain or spinal column since it can cover the target area more efficiently than the scattering method.
