Optimization of DLG and MLC transmission factors

Stephen Martinez, et al, Vanderbilt University Medical Center, Nashville (USA)


The clinical physics group aimed to compare the capability of the iQM system for optimizing MLC model specific parameters: Dynamic Leaf Gap and Transmission Factor to a IBA MatriXX spatial array. IQM shows a VERY small variation in the measured results and is able to clearly determine the best match of the minimum percent absolute error between predicted and measured signal. Download the poster to learn that IQM facilitated a higher resolution (0.01 mm) measurement than was possible with MatriXX..
