BEAMSCAN® MR

The first motorized 3D water phantom suitable for clinical use in a 1.5 T MR environment

Benefit from a complete solution for commissioning and QA of MR-LINACs – from automatic beam data acquisition, processing and analysis to protocol-based documentation. Built to the highest quality and technology standards, BEAMSCAN MR is exceptionally robust, incredibly versatile and straightforward in its operation. As an all-built-in system, it comes ready to use on a single carriage, including everything needed. A comfortable touch panel guides you step by step through the installation and setup process.

BEAMSCAN MR Highlights

  • Dedicated 3D water phantom for use with MR-LINACs ( ≤ 1.5 T)
  • Two models with vendor-specific water tanks for optimized scanning ranges:
    568 mm x 145 mm x 355 mm for Elekta Unity,
    408 mm x 248 mm x 355 mm for ViewRay® MRIdian®
  • All-in-one, ready-to-use system with comfortable touch panel for fast setup
  • Auto alignment – no lasers or light field needed
  • Maximum speed of 30 mm/s for faster scanning
  • Reference-class Semiflex 3D ionization chambers for precise dose measurements in small and standard fields up to 40 cm x 40 cm
  • Quick axial and radial detector setup with patented TRUFIX®
  • Consistent detector orientation for all scans, including off-axis scans
  • Fast, sensitive electrometer with excellent signal-to-noise ratio for perfect scans in all field sizes
  • Straightforward operation – from setup to documentation

STARCHECKmaxi ® MR

Comprehensive machine QA for MR-LINACs with one single device

As a flat-panel ionization chamber array, which is quick and easy to set up on the treatment couch, STARCHECK MAXI® MR combines versatility with outstanding efficiency. One shot delivers all relevant beam data for radiation fields up to 40 cm x 40 cm, eliminating the need to set up a 3D water phantom in daily routine or after service and repair.

STARCHECK MAXI MR Highlights

  • The only detector array to measure radiation fields up to 40 cm x 40 cm
  • Fast acquisition of all relevant beam parameters in one single measurement
  • Real-time display of beam profiles and analysis results for consistency checks and beam steering  
  • Highest spatial resolution (3 mm) for outstanding accuracy in all field regions,  including the penumbra
  • Optimal detector layout and density for QC measurements –
    707 air-vented ionization chambers arranged in a star pattern
  • Gold standard ionization chambers – no need for frequent recalibration
  • Expert analysis tools, e.g., profile comparison, protocol-based analysis, movie mode
  • Fully integrated with Track-it for automated reporting
