A shape descriptors comparison for organs deformation sequence characterization in MRI sequences

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 pathological grade determination as well as to the comparison of a real sequence to a simulated one. Shape descriptors are used to quantify the organs deformation along real patient MRI sequences. We show the method consistency and some promising results.
