Patient specific online characterization of abdominal
organ motion will open the possibility for adaptive
radiotherapy treatment that accounts for day to day
variations in tumor motion and motion of surrounding
organs. In this abstract we propose an online method,
based on retrospective binning of the data with respect
to the respiratory cycle, which allows 4D motion
characterization in less than 15 minutes. The method
utilizes a clinically available pulse sequence, and
Matlab based reconstruction and post-processing
software.
