Schematic representation of the process in generating the (A) pre-SABR tumour contour and (B) post-SABR tumour contour. The pre-SABR contour was generated using a k-means clustering algorithm with 5 features. Following this, the post-SABR pre-contrast image was registered to the pre-SABR pre-contrast image and the deformation field was applied to the pre-SABR contour.
