Varian gets FDA OK for scanning algorithm

Radiation therapy firm Varian Medical Systems of Palo Alto, CA, has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for a new proton scanning dose algorithm.

The algorithm is designed to give clinicians greater control over how proton beams are used to target tumors and other abnormalities. It is incorporated into Varian's Eclipse treatment planning software, which helps caregivers plan for intensity-modulated proton therapy by optimizing dose distributions in three dimensions to protect surrounding healthy tissues.

The proton scanning technique is intended to enhance current proton delivery methods that require a therapist to enter and exit the treatment room numerous times throughout a treatment to adjust physical compensators for processing proton beams.
