Accuray Initiates Sales of the VitalHold™ Solution in Japan, Supporting Surface-guided Radiation Therapy on the Radixact® System

December 5, 2023 at 7:30 AM EST

MADISON, Wis., Dec. 5, 2023 /PRNewswire/ -- Accuray Incorporated (NASDAQ: ARAY) announced today that the company has initiated sales of the VitalHold™* package supporting surface-guided radiation therapy (SGRT) on the Radixact® System in Japan beginning November 30, 2023. The VitalHold feature incorporates SGRT capability on the Radixact System using the Catalyst+ HD system manufactured by C-RAD, making it possible to deliver deep inspiration breath hold (DIBH) treatments, primarily for breast cancers, and perform markerless patient setup. The addition of this new feature will enable medical teams using the Radixact System to offer a wider range of radiotherapy treatment options using one device.

SGRT is a technology that supports highly accurate positioning by scanning the patient's body surface with a high-resolution camera and reconstructing it as a 3D image in real-time. The reconstructed image enables clinicians to easily visualize the difference between the current body position and the target position, helping to ensure high reproducibility of the patient position during treatment.

Heart dose from left-sided breast radiotherapy has been associated with a risk of cardiac injury1. In recent years, DIBH irradiation has become the standard of care for the treatment of left breast cancer to help minimize the heart dose. DIBH is performed by asking the patient to take a deep breath to physically separate the chest wall and targeted tumor from the heart. SGRT technology, which helps confirm the patient is appropriately positioned to deliver radiation, is widely used to facilitate these treatments. SGRT may also help reduce stress on the patient because it doesn't require permanent marks or lines on their body to verify they are in the correct position.

"We are very pleased to now offer VitalHold to our customers to support surface-guided radiotherapy using the Radixact System. With its introduction, markerless patient setup is now possible, and deep inspiration breath hold treatments can easily be performed to care for people with breast cancer. This is expected to greatly reduce the burden on medical staff and patients," said Juki Hozumi, President and General Manager of Accuray Japan K.K.

Continued Mr. Hozumi, "Since the introduction of the TomoTherapy® platform we have continued to enhance its functionality. Now, the latest generation Radixact System is one of the most versatile radiation delivery devices available and in the Japanese market, there are over 100 units routinely used to treat cancer. The VitalHold package is the newest feature of the Radixact System and we are confident it will be used to treat many diseases, including breast cancer. This technological innovation represents a new step forward and we will continue to work to further contribute to the advancement of radiotherapy."
