Stealth Chamber
Small field scanning accuracy with ease and precision
Unique Stealth reference chamber is the ideal solution for superior Ethos™ / Halcyon™ and SRS /SBRT beam commissioning.
The special holder enables tight attachment to the water phantom and compensates for the absence of light field.

Blue Phantom Compact
The right fit for Ethos™ /Halcyon™ 1) validation & required scans
The 2D water phantom with a small footprint ideal for doughnut-shape machines with a narrow bore.
Minimized weight for setup on the couch table, maximum functionality for advanced scanning.

Rotating Table
Seamless rotation of the filled 2D water phantom for in-plane and cross-plane measurements.
Avoids the need to drain the water phantom and enables faster commissioning and QA scans.
myQA SMARTSCAN automated and guided beam scanning
myQA SMARTSCAN now supports automated and guided beam validation for Ethos™ / Halcyon™.
Faster workflow through templates and optimized queues.

Independent Validation of Ethos™ / Halcyon™
- Independent QA enables an autonomous and unbiased validation of the machine and is the basis to allow detection of more machine and treatment issues.
- myQA HALO™ is the dedicated, proven package solution for independent commissioning & validation.
- myQA HALO™ enables a reliable beam data collection of the Varian Ethos™ /Halcyon™ as well as monthly and annual scans.

myQA HALO™ independent commissioning solution enables the Radiation Oncology Center at MedStar Southern Maryland Hospital Center fast clinical implementation of a Varian Halcyon® and Ethos™ 1)

IBA Dosimetry Solution used to accept the First Varian Halcyon® and Ethos™ 1 in the United States
IBA Dosimetry QA solutions used at The University of Pennsylvania to accept their new Varian Halcyon® and Ethos™ 1 linear accelerator.
Chris Kennedy Ph.D. DABR, Medical Physicist at UPENN: “We had a very good experience using our Blue Phantom solution to validate our Varian Halcyon® and Ethos™ 1 Linac. We actually used the same equipment that Varian® used when they did their original commissioning of the treatment planning system. The setup was very straightforward, and the flexibility of the myQA Accept software was essential for aligning the detector using the image-based methods necessary for Halcyon®. The bulk of our validation work was done in 3 days.”
