A model patient: Female pelvic anatomy can be viewed in diverse 3-dimensional images with a new interactive tool.

摘要

Case notes We developed, in portable document format (PDF), a detailed 3-dimensional (3D) interactive anatomic model of 23 pelvic structures that include the muscles, ligaments, and fascia of the pelvic floor and the organs it supports. Bones, blood vessels, and the perineum are illustrated as well. To produce this tool, 3D volumetric models were created from serial 5-mm-thick images that were obtained with a 3-Tesla magnetic resonance scanner. The subject was a healthy, 45-year-old, multiparous woman who was at the 50th percentile for height. Magnetic resonance images were then imported into 3D Slicer software (version 3.4.1; Brigham and Women's Hospital, Boston, MA). Each structure was traced with the use of the most clearly visible axial and/or coronal plane images and lofted into a 3D virtual model that was based on our previous anatomic work. Models were validated against the original scans and tracings. Next, the 3D models that had been generated by 3D Slicer were imported into Adobe 3D Reviewer (version 9.0; Adobe Systems Inc, San Jose, CA), exported as a universal 3D file, and, with the aid of the program's 3D tool, inserted into Adobe Acrobat 9 Pro (Adobe Systems Inc) and saved as a PDF file.
