... Study at Emory Shows Varian Medical Systems' On-Board Imager(TM) Device Improves Tumor Targeting Without Slowing Clinical Workflow Study at Emory Shows Varian Medical Systems' On-Board Imager(TM) Device Improves Tumor Targeting Without Slowing Clinical Workflow PALO ALTO, Calif., March 27 /PRNewswire-FirstCall/ - Varian Medical Systems' On-Board Imager(TM) (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.

"We showed that it is clinically practical to treat cancer using new image-guided radiotherapy techniques without slowing the operations of a busy radiation oncology department," said Tim Fox, PhD, lead author of the study and director of medical physics at the Emory University School of Medicine.

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 ...
