Abstract

The objective of the study was to prove magnetic resonance imaging as suitable instrument for exploring the nature and amplitude of displacements within the bony pelvis induced by asymmetrically altered pelvic floor muscle characteristics. Repeated MR imaging of 14 females was performed. Spatial coordinates of 23 pelvic landmarks were localized in each subject and registered by interactive and automatic procedures. Modalities of registration procedure were tested and compared by the precision of registration. The software tool was developed to perform registrations and data analyses including individual registration error evaluation. The automatic registration with vertebra L5 as reference has been found optimal. The study has demonstrated benefits associated with processing of MRI data in terms of high detection reliability of pelvic configuration. The precision of MRI data processing, tested in the study, may contribute to the enhanced accuracy of MRI data registration, easier data manipulation and analysis.
