MR-images of the prostate region from healthy volunteers acquired at Elekta unity MR-Linac at Uppsala University Hospital. Data from each volunteer consist of an initial T2-weighted scan, followed by a number of groups of paired low and high resolution data approximately 5 minutes apart with a 3D balanced steady state free precession sequence. The initial T2-image and all high resolution images are segmented by a single observer including prostate, bladder and rectum.
