QUASAR Multileaf Collimator (MLC) Beam Geometry Phantom by Modus

Description

The QUASAR MLC Beam Geometry Phantom is designed to address the complex non-dosimetric, beam geometry and beam imaging features of treatment planning systems.
The QUASAR MLC Beam Geometry Phantom is a useful tool in machine commissioning, system characterization, and routine QA protocols.
This is in very good pre-owned condition. Please see photos.
Features
End-to-end QA
The QUASAR™ MLC Beam Geometry Phantom tests beam integrity from CT simulation and planning to the linear acceleration and portal imaging system. Reveals errors in beam imaging, DICOM transfer, registration, alignment, and orientation.
Compatibility
Perform beam-shaping QA with standard collimators, MLCs, mini MLCs, and micro MLCs from multiple vendors, including Varian, Elekta, Siemens, Brainlab and Radionics. This solution is used for IMRT, 3D conformal RT, and conventional RT.
Intuitive Design
QUASAR™ MLC Beam Geometry phantom’s simple design promotes efficient testing with visual pass/fail features. Verify beam shaping process and alignment accuracy on your LINAC system.
