Quantifying the Spatial Sensitivity of Helical Diode Arrays In SBRT Patient-Specific QA
To quantify Gamma Passing Rate (GPR) volatility in SBRT QA caused by the spatial coincidence of helical diode arrays (10 mm pitch) with high-gradient fields. While 3%/2mm criteria reduce alignment artifacts, more sensitive 3%/1mm criteria are recommended for...
