“It gives the company unique access to global cancer data,” Toth said.

ViewRay MRIdian Linac
In February 2019, ViewRay received FDA 510(k) clearance to market the new soft tissue visualization capabilities for its MRIdian Linac system, which combines a linear accelerator with an MR scanner, was cleared by the FDA in February 2017, and has treated approximately 5,000 patients.

Called SmartVISION, the technology doubles the frame rate of the MR from four frames per second to 8 frames per second.

“Essentially what this does is it gives you better tracking capabilities and more disease-specific imaging capabilities,” said Michael Saracen, vice president of clinical marketing at ViewRay.

There is also expanded high-definition visualization and enhanced contrast between different tissues, to assist clinicians with tissue visualization and beam contouring, a diffusion-weighted imaging feature that tracks treatment progress by distinguishing between tumor and normal tissues, and enhanced MLC speed to potentially reduce treatment time.

“The SmartVISION helps [clinicians] to do what they are doing, better,” Saracen said.

Zap Surgical
The company received FDA clearance in OCTOBER 2017 for its Zap-X stereotactic radiosurgery system. In January of this year it was used for the first time to treat patients at Barrow Brain and Spine in Phoenix. A second installation in Beijing is almost complete. The company is close to applying for a CE mark.
