Davies et al. reported ultrasound based peak and trough liver motion estimates under normal respiration as 10 +/- 8mm (range 5-17mm). The mean movements in other directions were less than 2mm. Other authors have investigated liver motion using CT and MRI scans. Shimizu89 et al. was the first to report three dimensional liver tumour motions using rapid sequence (one image in 1.5 seconds) MR images in 1999.
