Abstract
There are provided systems, methods and radiotherapy devices for monitoring the position of a subject during radiotherapy, which comprise obtaining an MR image slice of a subject that exhibits through-plane distortion, obtaining a pre-treatment image slice of the subject that corresponds to the MR image slice and exhibits through-plane distortion that corresponds to the through-plane distortion of the MR image slice, and comparing the MR image slice with the corresponding pre-treatment image slice.
