Conclusion:

Time- and labor-intensive operations in the current PSQA workflow have been systematically assessed for two clinical PT centers. SCs were defined to automate key processes with high manual workload, enabling phantom-less PSQA in a future OAPT workflow and beyond. In addition, they would also speed-up today’s pre-treatment PSQA workflow, providing an even broader benefit. This work therefore represents a relevant step towards the implementation of OAPT for industrial PT solutions, ensuring a high level of safety while speeding up the PSQA process. In the next step, tolerance thresholds for soft SCs will be determined in a retrospective study, followed by a sensitivity analysis.
