StereoPHAN

StereoPHAN

End-to-End Stereotactic Commissioning & QA

  • Stereotactic (SRS/SRT/SBRT) end-to-end testing and patient-specific QA
  • Adapters for Head-Frames and CyberKnife
  • Easy setup and assembly


End-to-end Quality

StereoPHAN is designed for end-to-end commissioning and quality assurance testing on all parts of the SRS process. StereoPHAN inserts and configurations are quickly exchanged with no tools or change in setup. It’s that simple, and that powerful.

Features & Benefits

  • Stereotactic (SRS/SRT/SBRT) end-to-end testing and patient-specific QA
  • Adapters for Head-Frames
  • Image fusion
    • Quality assurance of image fusion algorithms for CT and MRI imaging modalities
  • Dosimetry
    • Absolute, relative and point dose dosimetry QA measurements at isocenter with ion chambers; relative dose distribution using film
    • Dosimetry detector cabling remains outside of beam for interference-free dose measurement regardless of measurement setup
  • Geometric accuracy
    • Optical and geometric isocenter
    • Laser alignment
    • Indexed table positioning alignment and positioning coordinates
    • CBCT and MV/kV isocenter alignment
  • Easy setup and assembly
    • No tools required for assembly
    • Stand base can be mounted to a couch that uses the prevalent Lok-Bar™ system
    • Phantom stand holds the inser ts, making them easily accessible during testing
  • Inserts
    • Single cube insert tests CT and MRI imaging, including slice position, thickness and alignment
    • Target volumes in CT/MRI cube eliminate need for CT/MRI markers
    • Flat surface of ion chamber insert enables easier cross-calibration to water than the curved surface of a spherical geometry
  • All components fit into a durable rolling case suitable for storage and air travel

SRS MapCHECK™ - SRS Patient QA, No Film


Designed to insert into the StereoPHAN, the SRS MapCHECK™ supports patient-specific QA for linac-based and CyberKnife treatment machines.

  • Replaces film, providing absolute and relative dose measurement in a single measurement.
  • Detector spacing and resolution specifically designed for stereotactic applications
    • Array size: 77 mm x 77 mm
    • Measures field sizes as small as 5 mm
    • 5 diodes in 5 mm cone
  • Easy-to-use and efficient software

StereoPHAN Inserts

MultiMet-WL

Verifies accuracy of single isocenter multiple metastasis SRS treatments

CT/MRI

CT/MRI insert verifies the accuracy of an image fusion algorithm. It includes three spherical cavities of varying sizes filled with mineral oil that are clearly visible in CT and MRI images. 3D volumes allow the user to perform true 3D image fusion by examining the accuracy of the fusion on multiple CT and MRI slices.

MRI Signal Generator

MRI Signal Generator insert with liquid-filled cavity aids in MRI image acquisition (optional).

Ion Chamber

Ion Chamber insert measures dose and positions active volume at geometric center of the phantom. To ensure a snug fit, each ion chamber insert is drilled to accommodate the ion chamber specified by the user.

Universal Spacer

Universal Spacer insert precisely positions the measurement inserts in phantom cylinder. It features five aluminum spheres at varying depths for CT-CT or CT-radiograph fusion. No separate set of markers required.

Multi-Film

Multi-Film insert supports relative dosimetry measurements and features three planes for placement of radiochromic film. The insert provides an option for cases involving multiple mets.

Film

Film insert measures dose profiles and features five titanium fiducial markers and orientation marks. Easy disassembly reduces chance of damaging film when removing insert from cavity.

Accessories

CyberKnife® Support

Perpendicular Film

Film insert measures dose profiles and features 24k fiducial markers and orientation marks as well as perpendicular film orientations (uses same film as Accuray® phantom).

CT

CT/MRI insert verifies the accuracy of an image fusion algorithm. It includes three spherical cavities of varying sizes filled with mineral oil that are clearly visible in CT and MRI images.

Chamber

Ion Chamber insert measures dose at the geometric center of the phantom.
