Robustness testing of MLC optical sensors for use in leaf open time reconstruction and online delivery verification

Leaf OS signals provide a reliable measurement method for LOT reconstruction on the Radixact platform. The OS LOT reconstructions are a practical solution for online treatment delivery verification as part of the PSQA process for OART workflows. This work provides the basis for future needs in MLC OS QA on the Radixact system as well as evidencing future studies to better understand the relationship between individual LOT reconstruction and delivered dose.
