Abstract

This work measured time taken to integrate image-guidance with CBCTs in routine clinical practice for patients treated between 2007 and 2010 across eight linear accelerators. 117,301 CBCTs from 4592 patients across thirteen disease sites were included. The mean image assessment decision time was 79s. Decision time was correlated with setup displacement magnitude.

Keywords: Cone-beam CT; Image registration time; Inter-fraction motion.
