—Dynamic magnetic resonance imaging (MRI) acquisitions are used in the clinical assessment of the pelvic organs behaviour during an abdominal strain. The main organs (bladder, uterus-vagina, rectum) undergo deformations and intrinsic movements along a sequence. Anatomical references and measurements are generally used by clinicians to evaluate pathology(More)
Dynamic MRI sequences are clinically used for the assessment of pelvic floor disorders. The organs complex movements are observed in the median sagittal plane. An objective characterization of the deformations that occur could allow an estimation of the similarity of the sequences. This quantification could pave the way to sequence classification or(More)
Pelvic floor diseases cover pathologies of which physiopathology is not well understood. 2D sagittal MRI sequences used in the clinical assessment allow to visualize the dynamic behavior of the main organs involved (bladder, uterus-vagina and rectum). Clinicians use anatomical landmarks and measurements related to the pelvic organs in their pathology(More)
In various imaging applications, shape variations are studied in order to define the transformations involved or to quantify a distance between each change performed. Regardless of the way the shapes may be extracted, with 2D imaging, shapes concern essentially curves or sets of points depending on the available data. Wether time is related to the shape(More)
