A decision tool for radiographer-led abdominal image-guided stereotactic ablative body radiotherapy – Experience from a single institution

•A CBCT decision tool was developed for radiographer-led IGRT for abdominal SABR.•This tool increased the confidence of radiographers undertaking online CBCT IGRT.•Median online review time was reduced by 1m 8s. A decision tool for radiographer-led image-guided radiotherapy (IGRT) using cone-beam CT (CBCT) for abdominal stereotactic radiotherapy was developed and successfully implemented in a single department. The confidence of 7 therapeutic radiographers when undertaking online CBCT review increased, and the pooled median online match time was reduced by 1 m 8 s. While this may be advantageous for abdominal SABR, further evaluation of this work in a larger cohort is required to validate these results.
