Abstract:

Actually there are few studies that analyze in detail the radiological anatomy of the female pelvis using 3D models coregistered with sectional images, making use of open applications for the representation of virtual scenes on low cost Windows platforms.

We present a computer development that allows visualizing and interacting in a virtual environment with the main anatomical structures of the female pelvis and its main arterial and venous vessels, reconstructed from serial sections of high resolution magnetic resonance. The possibilities of three-dimensional representation of these structures in any spatial orientation, together with sectional radiological images of magnetic resonance in the three planes of space (axial, coronal and sagittal) facilitate the anatomical comprehension and identification of all the bony, muscular, visceral and vascular elements of this region. Our technological procedure allows the observation of the main anatomical elements in three dimensions, at the request of the user, having as reference the magnetic resonance cuts, with a very intuitive graphical interface based on floating menus.

This computer application represents an important tool for the medical training of specialists in gynecology, as well as a previous step in the planning of surgical interventions of the pelvic floor.

The 3D visualization of the anatomical structures of the female pelvis, embedded in the volumetric data of magnetic resonance, constitutes the clearest and the most intuitive form of morphological analysis, because of the individual examination of the images of the different sections that compose a sequence of resonance magnetic allows us a simple understanding of the set of anatomical components that constitute this body zone.
