Three-dimensional Anatomical Structure Modeling: Patient Specific

Three-dimensional Anatomical Structure Modeling: Patient Specific

Today's computer technologies have made it possible to view anatomical structures in 3-dimensional (3D) by using sequential tomographic images. The 3D visuals of the patient's anatomical structures are important in terms of being a stepping stone to mathematical analysis of physiological processes. In this respect, 3D models are accepted as an important tool in estimating the criteria related to the course of some diseases, planning treatments specifically for the patient and risk assessment. In this study, the application of a software, TT3D-BMMP, developed in our laboratory in order to contribute to scientific knowledge in this field, is discussed. Materials and Methods: The software includes determining the boundaries of anatomical structures from tomographic section images (segmantation), placing the data in the 3D Cartesian coordinate system, and creating a surface mesh suitable for 3D visualization, respectively. The software application developed with the Delphi programming language defines the boundaries of the targeted anatomical structure automatically and by drawing / correction method when necessary. Automatic object recognition (feature extraction) procedure uses the 'radial map' algorithm and the surface network is stored in popular file formats. Results: This 3D organ reconstruction software, which requires minimal user interaction, was developed on anonymous patient images taken from open source web pages. Some model printouts have been produced and tested with 3D printer technology. The produced solid models were evaluated by making shape and scale comparisons with tomographic section images. Conclusion: We believe that this software will pave the way for multidisciplinary study possibilities for computational analysis of physiopathological parameters based on patient-specific anatomical models.
