Evansville Cancer Center First to Utilize Clinac iX™ Medical Linear Accelerator to Treat Cancer with Dynamic Targeting™ Image-Guided Radiotherapy
New Technology Delivers Ultra-Precise Radiotherapy Treatments with Pinpoint Accuracy

According to the American Cancer Society, there will be approximately 1,437,180 new cancer cases in 2008. While the number is startling, cancer experts at Evansville Cancer Center –Vantage Oncology believe there is light at the end of the tunnel are thanks to recent advancements being made to fight this terrible disease.

In particular, the field of radiation oncology is providing some of the most exciting and promising developments in the treatment of cancer. Evansville Cancer Center – Vantage Oncology is doing its part to further advance this trend by being the first in Evansville to offer the Clinac iX™ medical linear accelerator from Varian Medical Systems, Inc. Since 2006, this innovative technology has helped Evansville Cancer Center’s experienced team of radiation oncologists treat cancer with Dynamic Targeting™ image-guided radiotherapy (IGRT). The Clinac iX can deliver conventional, 3-D conformal and intensity-modulated radiotherapy (IMRT), and it uses special image-guidance technology to further enhance the accuracy of its tumor targeting.

“This state-of-the-art system enables us to treat patients with the most advanced radiotherapy techniques, using the most clinically efficient processes in the world,” said Dr. Jon D. Frazier, radiation oncologist and medical director of Evansville Cancer Center. “It provides us with tremendous versatility and precision for customizing treatments according to the specifics of each patient’s case.”

Beam Shaping and Patient Positioning
The Clinac iX is a high-power medical linear accelerator, a machine that rotates around the patient to deliver radiotherapy treatments from nearly every angle. It enables clinicians to concentrate radiation doses on the tumor while protecting surrounding healthy tissue. This means that it can deliver high doses of radiation quickly and with great precision. That translates into fast treatments, greater patient comfort, and the potential for better outcomes.

The technology also incorporates a multileaf collimator for shaping the radiation beam to match the three-dimensional shape of the tumor, and a robotic On-Board Imager™ device for fast, accurate, real-time tumor tracking and automated patient positioning.

Dealing with Tumor and Respiratory Motion
The Clinac iX also incorporates technology that helps doctors deal with tumor motion during treatment. An infrared monitoring device turns the radiation beam on and off at a predetermined point in a patient’s breathing cycle to compensate for motion due to respiration.

“This important tracking technology enables us to treat lesions that might not have been treatable in the past,” said Dr. Frazier. “We are able to protect healthy tissues to an unprecedented degree. By combining the a powerful radiotherapy treatment machine with high-quality imaging, tracking, and monitoring devices, the Clinac iX allows us to deliver the most accurate treatments possible. That translates to better outcomes along with greater patient comfort.”
