and 8) patient leaving the room. An in- house developedquestionnairewasused to assess pati ent satisfaction. Results: Results: 41patients with spinal metastases and four patients with non-spinal metastases were treated using the simulation-freeoART workflow. The median [IQR] overall treatment time for the simulation- free oART treatments was 29.4 minutes [IQR = 26.2; 36.1] compared to an overall treatment time of 23.0 minutes [18.0; 27.0] for 44 IGRT treatments (Figure 1). Figure 2 shows the time consumption for each step in simulation-free adaptive treatments for each patient. Despite the longer treatment times, patients reported high satisfaction, with 100% of the patients indicating they would prefer a simulation-free oART workflow if referred for radiotherapy again.
Conclusion: Conclusion: A simulation-free oART workflow was successfully implemented in the clinic within existing resource constraints for patients referred for single- fraction treatments. All patients reported high satisfaction with the workflow. Future work will focus on improving the treatment of soft tissue components, expanding to multi-fraction treatments, and developing an RTT-only workflow suitable for routine use.
