Varian Medical Systems' On-Board Imager (OBI) device for delivering image-guided radiation therapy (IGRT) efficiently improves tumor targeting, according to a study by clinicians at the Emory University School of Medicine, recently published in the Journal of American College of Radiology.   

Using Varian's On-Board Imager, the Emory research team measured the time required to deliver image-guided treatments and found that the process can be smoothly and efficiently integrated into the department's normal clinical workflow.

The On-Board Imager and associated processing software were used to generate and analyze radiographic kilovoltage (kV) x-ray images prior to each patient's treatment, compare them with reference images from the treatment plan, and fine-tune the patient's position for treatment. The average amount of time it took to generate the images and reposition patients dropped from an initial 7 to 8 minutes, when the technology was new to the clinical team, to a constant 3 to 4 minutes per patient after a year's experience.
