Addressing the challenges of motion management in radiotherapy

Posted on Jul 21, 2011

The ideal way to ensure accuracy during prostate treatments and spare critical structures is not just to see the motion, but also the ability to act on what is seen. For example, some radiotherapy treatment systems now offer intelligent and adaptive technology capable of tracking and correcting for prostate movement.

This allows clinicians to reduce treatment margins, include less normal tissue in the treatment area, and minimize radiation exposure to the rectum, urethra and neurovascular bundles. The benefits include preservation of erectile function and acute and chronic urethral and rectal toxicity rates comparable to conventional radiation therapy and surgery.
