Stereotactic Radiation Therapy

Catalyst HD now has a new dedicated model for Stereotactic Radiation Therapy (SRT) that provides higher accuracy, workflow automation to improve patient safety, and improved hardware robustness.


  • Improve EFFICIENCY

Intuitive workflow

The new workflow with its automated procedures has minimal impact on the clinical SRT workflow. The auto QA validation check and auto patient data retrieval minimize any human error to provide extra security to the patient. The Auto open-mask cutoff and high-resolution 3D imaging simplify the workflow with better surface image quality. The report generator records the status of setup and motion during treatment.

  • Real time IGRT for Stereotactic delivery – beam hold capability
  • Less chance for human error
  • Integrate with immobilization devices, i.e. Open mask
  • Improve efficiency

Improved high accuracy

Accuracy is improved independently on gantry angle and couch rotation with high-resolution imaging, which is extremely important for non-coplanar delivery.

  • Submillimeter clinical accuracy
  • No compromise with non coplanar position
  • Match Linac vendors’ requirement as IGRT modality

Integrated QA procedure

A fast QA procedure and auto QA validation check make the QA process simple and easy. System stability has been improved to support the longer treatment times needed for stereotactic delivery.

  • Integrated into the automatic workflow
  • Easy of use
  • Improve efficiency by reducing QA before every SRS case
