Cancer treatment system sculpts radiation beam to match shape of a tumor

Business Announcement

Rush University Medical Center

CHICAGO—Rush University Medical Center will begin offering in late March a new stereotactic radiosurgery treatment program with the latest radiation therapy technology available.

The new imaging and radiosurgery treatment system, called VarianTrueBeam STx, is capable of fast and precise noninvasive image-guided radiation therapy. Radiosurgery operates by directing highly-focused beams of ionizing radiation with high precision to a tumor.

"Radiosurgery platforms like TrueBeam can give hope to patients with inoperable or surgically complex tumors, as well as those seeking an alternative to conventional cancer surgery or radiation therapy," said Dr. Aidnag Diaz, medical director of Rush Radiosurgery. This will transform the treatment of many types of cancer such as head and neck, lung, liver and spine, cancers."

During treatment, the machine rotates around the patient to deliver radiation with a radiation beam that is aimed directly at the tumor site. The radiation beam is sculpted and shaped to match the three-dimensional shape of the tumor, helping protect nearby healthy tissue and critical organs. This is a noninvasive treatment where patients usually return to normal activities immediately following treatment.

The system can be tailored for a particular cancer treatment and has a control system that automatically detects patient position and motion, and manages radiation beam shaping and dose delivery. When the system is in use, it performs accuracy checks measured in increments of less than a millimeter every 10 milliseconds throughout the entire treatment.

"It can be challenging for a patient to be completely still during a 45-minute treatment," said Diaz. "This technology will allow us to treat a patient within 5 to 15 minutes, a fraction of the time, helping us to provide faster, more precise treatment even during movement. Rush Radiosurgery is being developed through a joint venture between Rush University Medical Center and US Radiosurgery of Alliance Oncology. Rush Radiosurgery is a part of the Department of Radiation Oncology at Rush.

"The development of Rush Radiosurgery and the addition of TrueBeam STx technology further illustrates our mission to provide patients state-of-the-art cancer treatment options and the highest quality of care," said Dr. Diaz.

The center is located in at Rush in the Woman's Board Center for Radiation Therapy at 500 South Paulina Street in Chicago. For more information, call 312-942-4600 or visit www.rushradiosurgery.com.

Rush is a not-for-profit academic medical center comprising Rush University Medical Center, Rush University, Rush Oak Park Hospital and Rush Health.

In January 2012, Rush opened a new 14-floor, 806,000-square-foot hospital building near the corner of Ashland Avenue and the Eisenhower Expressway. The new hospital, is the centerpiece of a $1 billion, ten-year campus redevelopment plan called the Rush Transformation, which also includes completion of a new orthopedics building, a new parking garage and central power plant, renovations of selected existing buildings and demolition of obsolete buildings. The new hospital is designed and built to conserve energy and water, reduce waste and use sustainable building materials. Rush is seeking Leadership in Energy and Environmental Design (LEED) gold certification from the U.S. Green Building Council. It will be the first full-service, "green" hospital in Chicago. The hospital was designed using "universal design standards," which ensure barrier-free accessibility for people with disabilities, and has exceeded many building code requirements to help everyone such as a mother with small children. More information and an interactive tour is accessible at transforming.rush.edu

Rush's mission is to provide the best possible care for its patients. Educating tomorrow's health care professional, researching new and more advanced treatment options, transforming its facilities and investing in new technologies—all are undertaken with the drive to improve patient care now, and for the future.
