First Patient Treatments on Radixact System with ClearRT Imaging

Accuray announced that the ClearRT helical fan-beam kVCT imaging capability has now been in clinical use for over two months at Willis-Knighton Cancer Center in Shreveport, Louisiana. ClearRT on the Radixact System is believed to have the potential to change the field of radiation oncology by enabling clinicians to easily, quickly and cost effectively acquire diagnostic-like quality CT images that enable them to “See More, Know More, and Do More,” when treating tumors with radiation.

The medical care team at Willis-Knighton Cancer Center in Shreveport, Louisiana has treated the first cancer patients in the world using the Radixact System and ClearRT imaging, integrated helical radiation delivery and imaging systems. The team has more than 18 years' experience treating patients with the TomoTherapy System and recently upgraded to the Radixact System, the next-generation TomoTherapy platform. The ClearRT imaging modality generated clear, high-fidelity images that improved the Willis-Knighton team's ability to see the tumor and surrounding healthy tissues, and deliver the treatment plan with more confidence and precision.

“At Willis-Knighton, we have always tried to introduce next-generation radiotherapy technology.  The Radixact System with ClearRT has the potential to change clinical practice. The ClearRT daily targeting images exceeded our expectations, and provided noticeably superior image quality compared to more traditional cone-beam CT available on conventional linear accelerators. The Radixact System with ClearRT imaging will allow our team to improve the care we provide our cancer patients by better visualization of tumors and adaptive therapy,” said Lane R. Rosen, M.D., director of radiation oncology at Willis-Knighton Cancer Center.

ClearRT is currently cleared for use in the US and Japan. According to Accuray, CE Mark in the European Union is expected in the company’s fiscal fourth quarter ending June 30, 2021.
