In the context of pelvic floor diseases understanding we advocate a process to observe the bladder over time in 3D. Thanks to multiplanar MRI acquisitions and adequate volume constructions, several volumes per seconds can show a bladder undergoing deformations under strain conditions. To our knowledge it is the first time such observation is performed. In addition we propose some deformation estimation clues that may be useful to pathology characterization and clinical diagnosis.
