New Solution Provides an Unprecedented Set of Tools, Empowering Clinical Teams With Choice and Flexibility to Deliver Adaptive Care—Tailoring Radiotherapy to Each Patient's Unique Needs

MADISON, Wis. , Sept. 26, 2025 /PRNewswire/ -- Accuray Incorporated (NASDAQ: ARAY) announced today that the company is advancing its legacy of leadership in adaptive radiotherapy with the introduction of the Accuray Stellar™* Solution. Initially for the U.S. market, the new Accuray technology is not just a system, it's a solution, comprised of a comprehensive tool set designed to empower clinical teams to address the evolving treatment needs of patients undergoing radiotherapy.

The Accuray Stellar solution, a configuration of the Radixact^® Treatment Delivery System, will be featured at Accuray booth #525 during the 2025 American Society for Radiation Oncology (ASTRO) Annual Meeting in San Francisco, California, September 28 – 30, 2025. Meeting attendees are invited to attend the U.S. unveiling at the company's booth on Sunday, September 28, at 11:30 am PT.

"Innovations in radiation medicine, such as adaptive radiotherapy, are enabling clinicians to deliver more precise treatments that can lead to better tumor control and potentially higher survival rates. Our goal with Accuray Stellar is to provide tools that make it simple, fast and practical for medical teams to adopt adaptive radiotherapy techniques where needed, regardless of the stage of the patient's cancer journey. The solution reflects our commitment to innovating with purpose and compassion, and to redefining what's possible in personalized, radiotherapy treatments," said Suzanne Winter, president and CEO of Accuray.

To broaden the reach of transformative cancer care, Accuray Stellar easily integrates with the company's proprietary software and hardware solutions ― and vendor partner technologies ― expanding the range of available radiation delivery options and streamlining the treatment workflow for each patient.

With Accuray Stellar, clinicians have access to a solution capable of the full range of delivery modalities, from image-guided radiation therapy (IMRT) to stereotactic body radiation therapy (SBRT) treatments and surface-guided ration therapy (SGRT), to optimize outcomes for standard radiation therapy indications including breast, prostate, lung, and head and neck cancers, in addition to complex treatments such as total marrow irradiation.

Accuray Stellar provides a unique option for accurately delivering radiation while correcting for changes in the size or shape of the tumor, and patient or tumor movement, that can occur while patients undergo care. The solution offers a versatile and simplified path to adaptive radiotherapy developed to provide the foundation for adaptive care that can evolve with each patient's needs. The adaptive suite ranges from real-time motion tracking and correction, with Synchrony^® technology, to offline adaptive protocols featuring PreciseART^®, as well as an online-adaptive ready interface (a prerequisite for OART**), providing the foundation for adaptive care that evolves with each patient's needs.

Medical care teams can also leverage one of the company's latest innovations, Adapt LTE*** powered by Accuray Cenos, only available on Accuray Stellar. Adapt LTE retrospectively evaluates previously delivered Accuray Precision treatment plans against original therapy objectives. It leverages adaptive tools to analyze historical treatment data to help clarify clinical decision pathways. It is designed for training purposes or post-treatment evaluation, enabling clinicians to build greater confidence and consistency in planning, contouring, and determining the appropriate use of adaptive technologies. This is a tool that allows clinicians to learn, trial and evaluate.

ClearRT^® helical kVCT imaging provides the foundation for Accuray adaptive radiotherapy technology. ClearRT is designed to acquire high resolution images with ease and speed, providing healthcare professionals with exceptional clarity of the tumor and surrounding anatomy. Better clarity in imaging will enable clinicians to make more informed decisions about all aspects of the patient's treatment and helps improve the quality of care for almost any patient who would benefit from radiotherapy.
