Radiation therapy test phantom QUASAR™ MLC Beam

general purpose

The QUASAR™ MLC Beam Geometry Phantom is designed to address the complex non-dosimetric, beam geometry and beam imaging features of treatment planning systems. IMRT and other conformal therapies have led to increased demands on physicists responsible for commissioning and maintaining radiotherapy equipment. AAPM Task Group reports, including TG 66(1), TG 53(2), and TG 51(3), make clear recommendations regarding the importance of both dosimetric and non-dosimetric testing. The QUASAR™ MLC Beam Geometry Phantom is a useful tool in machine commissioning, system characterization, and routine QA protocols. 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.
