Remaining uncertainty - deformations

On 8 volunteers, 6MRIs were performed. IMRT planning on Prostate +4mm was performed. Plan with the smallest treated rectal volume was taken as reference plan and copied all other scans.  Large influence of deformations on dose to the rectum.  Only small difference in the dose to the target.
