Abstract
A method is provided comprising: obtaining first and second datasets representative of first and second images of an object at different times, respectively; obtaining a deformation field, representative of changes between the first and second data sets, by performing a rigid or non-rigid registration; generating one or more masks and/or segmentations for selecting elements of the first image; selecting elements of the first image; transforming the first dataset using the deformation field to project the selected elements onto the second image; visualizing the deformation field or previously specified portions thereof; processing the deformation field or previously specified portions thereof to obtain data representative of different predetermined types of deformation; and visualizing the deformation field or one or more selected portions thereof, thereby to visualize the predetermined types of deformations separately and to enable a differentiation between changes in the patient and changes, in particular errors in the patient's position.
