Radiation therapy is constantly evolving. Push the boundaries.

Push the boundaries of your stereotactic capabilities

Cancer treatment is shifting from terminal to chronic disease management. This requires faster, more cost-efficient as well as safe and precise treatments for all patients.

We believe in making stereotactic body radiation therapy treatments dynamic, fast and easy. And now, Versa HD with HDRS delivers on both speed and precision, allowing any SBRT/SRS treatment to be delivered in a standard 15-minute timeslot.

Stereotaxy made easy

  • For brain with single isocenter high-definition dynamic radiosurgery (HDRS)
  • For lung with device-free 4D imaging and Elekta DCAT delivery in less than two minutes
  • For prostate with real-time soft tissue tracking and IntelliBeam treatment delivery in less than 90 seconds

Linac as a dedicated SRS solution

The Versa HD brain metastases solution, High-Definition Dynamic Radiosurgery (HDRS), offers unique sequencing capabilities—turning your linac into a dedicated SRS solution.

  • High-definition delivery for small targets
  • Faster treatments with fewer and shorter arcs
  • Robust template-based plan optimization
  • Frameless SRS/SRT with continuous SIGRT monitoring
  • End-to-end stereotactic accuracy

Next-generation sequencing

Traditional sequencing

  • No jaw optimization or tracking
  • Fixed and limited-control points
  • RLarge exposure of normal tissue to radiation
  • Inefficient delivery speed

Elekta HDRS sequencing

  • Jaw optimization across full 40 cm field size
  • 1,024 dynamic control points
  • Exceptionally low leakage through leaves and jawsMaximum transmission through leaves and diaphragm >0.07% for 6MV (Linac product data)
  • Sustain high modulation while delivering in high dose rate mode (FFF)
  • Organic reduction in normal tissue doses
  • 1 mm virtual leaf width

Noncoplanar verification with end-to-end confidence

Critical to achieving submillimeter positioning accuracy for multiple metastases cases, the HexaPOD robotic couch is guided by an infrared camera that enables submillimeter patient positioning accuracy in six degrees of freedom—correcting translational errors (x, y, z) and rotational errors (roll, pitch, jaw).

Auto-planned solution

Regardless of the number and location of the brain metastases, Monaco® templates provide robust optimization processes with automated dose reduction to organs at risk (OAR) for efficient dose calculation and optimization.

Robust template-based optimization

  • Automated isocenter placement
  • Beam geometry
  • Beam parameters
  • Calculation settings
  • DVH metrics and cost functions

Auto OAR dose reduction

  • Single-click auto-dose personalization, reducing dose to organs at risk

With Monaco DCAT and Versa HD, treatment time has been reduced significantly. SABR lung can now be delivered in a standard 15-minute time slot, including imaging.

Patient-friendly prostate SBRT

The Versa HD solution for prostate SBRT leverages robust anatomy-based plan templates with multicriterial optimization and next-generation beam sequencing, and it offers dose-free continuous soft-tissue monitoring.

Maximized delivery efficiency

  • Intelligent, high-definition, high-speed treatment
  • Variable control point sizes allow more modulation where required
  • Larger control point spacing in low modulation areas
  • Maximizes dose rate with shorter delivery time
