Accuray has released four new cancer treatment products at the annual meeting of the American Society for Therapeutic Radiology and Oncology in Los Angeles this week.

The Sunnyvale, Calif.-based Accuray unveiled these products:

• The Iris Variable Aperture Collimator for radiosurgery, which enables clinicians to define the amount, or dose, of radiation delivered during treatment while automatically altering the collimator opening to let radiation beams of 12 discreet sizes pass through.
• An 800 monitor unit (MU) per minute linear accelerator, which delivers higher dose rates of radiation to a tumor, thereby reducing treatment times, the company said.
• A Sequential Optimization planning tool, which enables users to establish their own clinical objectives to achieve more intuitive treatment planning in a shorter amount of time.
• The RoboCouch Patient Positioning System with Seated Load is an ergonomic treatment couch that has a built-in adjustable knee bolster that enables treatments to be performed either with the patient’s knees bent and up or in a flat, tabletop configuration.
