DETROIT – The Henry Ford Cancer Institute has treated the
world’s first cancer patient today with an advanced radiation therapy that uses
an FDA-cleared real-time magnetic resonance imaging and linear accelerator
delivery for more precise and accurate radiation treatment.
The MRIdian Linac by ViewRay, Inc. can treat cancer anywhere in the body. It is the world’s first
and only FDA-cleared commercially available linear accelerator-based MRI-guided
radiation therapy system that can image and treat patients simultaneously. The
FDA cleared use of the company’s next generation model in February.
This next generation MRIdian Linac system is a novel
radiation oncology technology that delivers:
- Confidence in accuracy and precision. Real-time high-quality MRI images and continuous soft-tissue imaging is done throughout the treatment automatically targeting the tumor and surrounding organs, ensuring the beam hits the targeted treatment area.
- Personalized treatment. By continuously observing and assessing the patient’s tumor and internal organs, clinicians can adapt in real-time, reshaping the dose to match each patient individually while on the table.
- Real-time imaging. When clinicians can clearly see the target and watch where the radiation is being delivered, they are better able to adapt to natural movement of the patient’s anatomy. Doctors previously did not have the tools to see organs in real time to make changes during radiation therapy.
The first clinical MRIdian Linac system is available at
Henry Ford Medical Center-Cottage in Grosse Pointe Farms. The first patient in
the world was treated there Wednesday, July 19 for prostate cancer. Using
this new technology radiation oncologists were not only able to see the exact
location of the prostate in real-time as it was being treated, but also the
neighboring normal structures, including the bladder and rectum.
“This is an incredibly exciting advancement in our field
that is unlike anything else in the world to treat cancer patients,” says
Benjamin Movsas, M.D., chair of the Department of Radiation Oncology at the
Cancer Institute and a national expert.
“Being able to continuously see both the tumor and
surrounding organs means our team can accurately align the tumor to the
treatment beams and make adjustments in real time to avoid sensitive internal
structures. For radiation oncologists, this exciting technology finally ‘takes
off the blindfold,’ and allows us to see during treatment what we could not
previously visualize. This is a major leap forward that will benefit cancer
The new system can be used to treat all types of cancers
anywhere in the body, and is especially beneficial for tumors where there is
typically movement during treatment, including tumors in the liver, pancreas,
adrenal and lung. Other types of cancer this advanced system will deliver a new
level of care to include breast, prostate, kidney, and gynecologic cancers,
Indrin Chetty, Ph.D., division head of Physics in Radiation
Oncology, says the MRIdian Linac system further enhances radiation therapy with
high-quality soft tissue images that make it possible to precisely align and
adapt to changes, as well as shrink margins while increasing doses.
“For a pancreatic cancer patient, for example, we can now
see the exact shape and location of the tumor as well as nearby critical
structures to avoid the stomach, liver and small intestine throughout the
treatment,” he says. “Now we can account for shape and position of the tumor to
its surrounding organs to safely deliver ultra-high doses offering a better
chance for local control.”
Over the years, technology has improved the accuracy of
radiation treatment while protecting surrounding healthy tissue. However,
trying to accommodate for the natural movement of a tumor and the body’s
internal organs during treatment has been elusive.
“We believe our system will lead to a new standard of care
in radiation oncology,” says Chris Raanes, president and CEO of ViewRay. “With
ViewRay’s first generation MRIdian system treating nearly all cancer types,
clinicians saw for the first time how much tumors and organs move and change
shape during the course of treatment.”
The ViewRay system combines the effectiveness of MRI, which
produces high-quality images of organs and structures inside the body, with a
linear accelerator to map out a therapy plan and deliver radiation at the
intended target, while allowing for refinements to be made in real-time during
treatment. The result is a more accurate, precise treatment.
“Our Department of Radiation Oncology has a long tradition
of expertise using the most advanced radiation technologies, and the ViewRay
system offers our patients another optimal treatment for achieving the best
care possible,” says Steven Kalkanis, M.D., medical director of the Cancer
Nearly two-thirds of all cancer patients in the United
States will receive some form of radiation therapy during their course of
treatment. In use for more than 100 years, radiation therapy damages the
genetic material in cancer cells and helps to prevent the cells from growing
and spreading. Treatments are delivered using specialized procedures to enhance
their safety and effectiveness.
