Conclusion Selected beam angles have a significant impact on IMRT plan quality for LA-NSCLC patients. Automated planning with integrated computerized BAO showed a great potential for enhanced OAR sparing compared to planning with manually selected angles. Dosimetric implications of increasing or reducing the number of beams were patient-specific, but overall, increasing the number of beams improved OAR sparing. Autoplanning allows for generation of several plans with different numbers of optimized beams to select the optimal number for each individual patient.
