"In our hospital network we've seen an increase in the use of hypofractionated stereotactic body radiation therapy as part of the cancer treatment, making it critically important that we are able to safely deliver the correct amount of dose precisely to the tumor, even to those that move such as tumors in thorax, abdomen and pelvis," said X. Allen Li, Ph.D., Medical College of Wisconsin Professor and Chief of Medical Physics at Froedtert Hospital. "Our comprehensive pre-treatment tests and the initial patient treatment showed us how well the Synchrony technology works in the real-world clinical practice. As a result, we now have an option for precisely and accurately delivering radiation to tumors as they move, which will expand the range of tumors we can confidently treat and the patients we can help."

Synchrony for the Radixact System is designed to correct for tumors that move as a result of bodily processes, including respiration and digestion, as well as patient movement. Synchrony is the only technology that uses image guidance during treatment delivery to automatically adjust the movement of the radiation beam in synchronization with the movement of the tumor. The beams of radiation are delivered continuously throughout the treatment session as the patient breathes naturally. In comparison, gating methods deliver radiation only when the tumor is close to the expected location and pause treatment delivery when the moving tumor is outside of the "treatment window." This potentially lengthens the treatment time and can compromise clinical efficacy.


Additionally, the combination of Synchrony® with the Radixact® System facilitates the efficient and effective delivery of both hypofractionated and standard radiation therapy, making it easier for clinical teams to provide treatments tailored to meet each individual patient's needs. This functionality directly supports the key priority of value-based healthcare delivery models, such as an Alternative Payment Model, which economically reward treatment quality and efficiency to improve patient outcomes. The combination of Synchrony® with the Radixact® System is a big step forward for patients, and clinical providers who treat them.

"We congratulate Dr. Schultz, Dr. Li and the entire Froedtert & MCW Cancer Network team on treating the first cancer patient using the Radixact System with Synchrony," said Birgit Fleurent, chief marketing officer at Accuray. "This treatment demonstrates the value that Synchrony for the Radixact System brings to the treatment of cancer and the Accuray team's commitment to providing clinicians with the resources they need to help them achieve their clinical objectives for all cancer patients, even those with tumors that move."
