Study of Sectional Anatomy and Visualization of the Female Pelvic ...

[Abstract]

The female pelvic cavity is an important region with a great many viscera. There are consanguineous affinities in urinary system, genitalia system and digestive system in female pelvic cavity. It is very useful in clinical diagnosis and treatment of diseases in the female pelvic cavity to recognize the complicated distribution and extensity of the anatomical structures in the female pelvic cavity through thin sectional anatomy and three-dimensional visualization. In this study, the acquisition technique of the visible human data set was used to obtain the visible female pelvic cavity. Meanwhile, the images of the female pelvic cavity were observed meticulously. After being registered accurately with Photoshop 7.0 software, the sectional images of the data set of anatomical structures in female pelvic cavity were reconstructed with 3D DOCTOR 3.5 and 3D Lancet 2.0 software on personal computer. With the support of visualization software Virtual Reality 1.0 which was provided by the Chinese University of Hong Kong and 3D Lancet 2.0 which was developed by our research group, the data set of the female pelvic cavity was visualized and displayed in three-dimensional space on personal computer. At the same time, the anatomic structures in female pelvic cavity could be observed clearly at any angle. The main results and conclusions were as follows.1. The 4 series (3 series pelvic data set with transverse and 1 series pelvic data set with sagittal planes) continuous thin sectional anatomy of female pelvic data set were obtained by the acquisition technique of the visible human data set. The thinnest serial sections of pelvic layer were sampled at 0.2mm. And the resolution of sectional image reaches to 1,100,000 pixels, with each TIFF, file occupying 31.5MB.2. After being matched accurately, the thin sectional images of 1 series pelvic data set with transverse planes were compared with the CT and MRI of the female pelvic cavity from the visible human data set. The anatomic structures of the female pelvic images were observed and measured.3. After being recognized and segmented by the Photoshop software, each importantstructures in the female pelvic cavity including the pelvis, the uterus, the ovary, the ureter, the vesica, the internal iliac vein and artery, external iliac vein and artery were reconstructed with 3D DOCTOR 3.5 and 3D Lancet 2.0 software on personal computer.4. Enlightened by the think of digital brain atlas of Talairach, the tri-dimensional coordinate system was established on the symbol of typical anatomic structures on tri-dimensional model of the female pelvic, which can be used for study minute anatomic structures, for medical image fusion and registration, for model driven segmentation and for the teaching of anatomy.5. The creation of visible female pelvic model can be used for the digital anatomy teaching, and for the gynecological surgical navigation planning and three-dimensional conformal radiotherapy of female pelvic cancer.6. Take example for radiotherapy of cervical cancer, the continuous thin sectional anatomy of female pelvic data were used to study the anatomical morphology and the clinical dosemetry of radiotherapy fields in radiation treatment planning for cervical cancers.
