In this research, an interactive software tool has been developed for creating 3D models of anatomical organs and other body structures from 2D medical imaging data.
3D models are generated by using the Marching Cubes algorithm and Planar Contour
method by SolidWorks developed in Visual Basic Language. The research includes
transferring CT and MRI images into digital binary matrixes, entering digital binary
matrixes into SolidWorks environment, building feature library for 3D reconstruction,
creating medical rapid prototyping models, and performing biomedical rapid design and manufacturing. CT and MRI images processing is obtained by capturing the patient scan data, converting the image format, extracting the gray scale of bone image, and transferring CT and MRI image into digital binary matrixes. 3D reconstruction is created by edge configuration generation and triangulated cube configuration generation in Marching Cubes algorithm and by capturing section contour points from medical image per slice, creating B-spline curve with the control points in each layer, producing solid model construction in Planar Contours method. Medical rapid prototyping models are performed in SolidWorks, including three views or any combination of views, for biomedical rapid designing and manufacturing according to the biomedical needs. Layered manufacturing techniques are used for producing parts of arbitrary complexity. The results of this research are the first to develop image processing 3D visualization in SolidWorks Application Programming Interface (API) using Visual Basic Language. The system performance is tested using truth CT and MRI data, and 3D physical models teeth and knee joint for MRP are created directly from SolidWorks. The results reveal that the accuracy of 3D reconstruction is acceptable.
