Stage 1: 102/125 (82%) plans selected online concorded with offline RO review. Concordance per patient ranged from 64–96%. For the 23 discordant fractions, the HR-CTV was adequately covered, therefore impact deemed clinically insignificant. For 96% of fractions (112/125) a plan covering the entire target volume was available. Median time (range) taken from CBCT start to plan selected was 7 (2-12) minutes, time from CBCT start to treatment completed was 11 (4-22) minutes.

The imaging flowchart was refined ( Figure 1 ) and discordant plan selections reviewed with the RO and RTTs before stage 2.

Stage 2: RTT online plan selection rose to 90% concordance with offline RO review. For the five discordant fractions identified, one impacted HR-CTV coverage.

Stage 3: Twenty patients completed POD treatment within 14-months of implementation. Four plans were used for 13/20 patients, three plans for 6/20 patients and one plan for 1/20 patients ( Figure 2 ).
