Web2.1. Beam Characteristic Equivalence Monitor unit dose, linearity, and beam flatness/symmetry reproducibility with dose rate were evaluated using the Sun Nuclear IC Profiler™ device and v3.4.2 software. The IC Profiler was chosen as it has been previously demonstrated to be equivalent to water tank measurements detecting changes in these … WebNov 30, 2016 · A focal spot position adjustment of 0.4 mm (at isocenter) was measured with MPC beam center to within 0.01 mm. An average systematic offset of 0.5% was measured in the MPC uniformity and agreement of MPC uniformity with symmetry measurements was found to be within 0.9% for all beams.
