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.
Designed to insert into the StereoPHAN, the SRS MapCHECK™ supports patient-specific QA for linac-based and CyberKnife treatment machines.
Verifies accuracy of single isocenter multiple metastasis SRS treatments
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 insert with liquid-filled cavity aids in MRI image acquisition (optional).
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 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 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 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.
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/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.
Ion Chamber insert measures dose at the geometric center of the phantom.
