Verify IGRT setup accuracy in less than 5 minutes IsoCenter Cube KEY BENEFITS ± ± ± ± ± Quick simple Winston-Lutz testing for IGRT accuracy Minimize CBCT artifacts Software Analyze EPID radiation field exposures Analyze various shaping devices Report left/right, superior/inferior and anterior/posterior errors at configurable gantry, collimator and table angles The QUASAR™ IsoCenter Cube is designed to provide information needed to clinically implement a modified Winston-Lutz test for IGRT accuracy. Test end-to-end IGRT positioning accuracy for clinical treatment setups with 0.1 mm precision in less than 5 minutes. The test is performed by aligning a phantom containing radiopaque sphere with IGRT system, then capturing radiation field exposures with film or EPID. The test results are used to determine end-to-end accuracy for frameless SRS, SBRT, and IGRT treatments. Analyze IsoCenter Cube’s Winston-Lutz images with the IsoCenter Cube Software. ANALYSIS SOFTWARE ± Import and analyze EPID images ± Configure gantry collimator and couch rotation parameters ± Export results for trending purposes ± Define parameter and threshold templates Accuracy.
