Henry Ford Hospital used an MRIdian Linac device manufactured by ViewRay, the world's first and only FDA-approved commercially available MRI-guided linear gas pedal.
The MRIdian Linac is a second-generation product with the following features.1. High accuracy and precision: With high-quality simultaneous MRI imaging and continuous soft-tissue imaging, tumors and surrounding organs are automatically tracked during treatment to ensure that the radiation beam is aligned with the treatment area.2. Personalized treatment: By continuously observing and Personalized treatment: By continuously observing and evaluating the shape of the tumor and organs, doctors can adjust the shape of the radiation beam for each patient simultaneously.3. Synchronized imaging: When doctors can track and clearly see the area where the radiation beam is delivered, they can better grasp the anatomical positional changes caused by the patient's natural movements.
The world's first MRIdian Linac system was installed at Henry Ford Cottage Medical Center. Radiation oncologists can use the technology to see in real time the location of the tumor and surrounding normal organ structures during treatment.
Benjamin Movsas, Chief of Radiation Oncology, said, "This technology is a huge advancement in the field. The ability to see the tumor and surrounding organs continuously means that doctors can accurately modulate the radiation beam in real time and avoid damaging vital organs."
The new system can treat any part of the body and any type of tumor. It is particularly suitable for tumors that move during treatment, such as liver, pancreas, adrenal gland, and lung tumors. It is also suitable for other tumors such as breast, prostate, kidney, and gynecological tumors.
Indrin Chetty, Physics Group Supervisor, Radiation Oncology, said MRIdian Linac improves the effectiveness of radiation therapy by allowing the high-quality, soft-tissue imaging system to adjust the precise alignment of the radiation beams to accommodate changes in the tumor during treatment. For example, when treating pancreatic cancer, doctors can see the exact location and shape of the tumor and can avoid damage to vital organs such as the stomach, liver, and small intestine.
Over the years, advances in technology have improved the accuracy of radiation therapy while protecting surrounding healthy tissue. However, additional protocols are needed to address the positional changes associated with the natural movement of tumors and internal organs during treatment.
Steven Kalkanis, Medical Director of the Oncology Center, said, "Our hospital's Radiation Oncology Department has a long tradition of specializing in state-of-the-art radiation therapy. We believe the ViewRay system will provide patients with another treatment option."
July 30, 2014/PRNewswire:Study results published in October in Neurosurgery show that the EDGE Radiation Therapy System with RapidArc Technology is able to resect multiple brain metastases more effectively and with less damage [1]. This treatment technology is significantly superior to Gamma Knife and Cyberknife.
EDGE radiosurgery is more than six times more intense than Gamma Knife and Cyberknife and can remove multiple tumors at once, whereas Gamma Knife and Cyberknife can only remove one tumor at a time.
The removal of multiple brain metastases with EDGE can be accomplished in 22 minutes or less, whereas other radiation treatments, such as Gamma Knife and Radio Wave Knife, can take one to five hours.
