Varian adds On-Board Imager features

Varian Medical Systems has received Food and Drug Administration 510(k) clearance for a new suite of features on its On-Board Imager system for the Clinac and Trilogy medical linear accelerators. The new features allow On-Board Imager to synchronize image acquisition with a patient's respiratory cycle and automate "marker matching" for more precise tumor targeting, according to the Palo Alto, CA-based vendor.

An automated tumor marker-detection feature automatically positions a patient for treatment by detecting and imaging gold seeds or other fiducial markers implanted in a tumor, Varian said. The On-Board Imager can also now perform monitoring and gating for tumor motion, according to the vendor.
