Medical imaging is a set of specific examination procedures taking advantage of physical effects for determination of changes that occurred in patient’s body. It’s a domain of biomedical engineering to define the methods of acquiring, analyzing and visualizing medical images in the way useful for diagnostic, therapeutic, educational or research purposes. This work describes an effective method of automatic creation of 3D objects from the DICOM images.
At the beginning DICOM images are read. Then tissues are segmented with a simple thresholding algorithm and filtered. After filtering preliminary 3D model is created. Afterwards obtained geometry is smoothed and decimated to relax the model and reduce the size of data. Such prepared model is embedded into PDF file with use of additional scripts. As the result of this work software called DICOM2PDF3D, combining described above stages of building 3D model in a single procedure, was developed. With use of 3D PDF additional measurements of created geometry were made. Measurements confirmed values obtained from standard preoperative evaluation.
The presented solution allows creating and opening three-dimensional visualizations on every desktop computer even by inexperienced users. Created 3D PDF can be used for preoperative evaluation as an assistance for standard procedures.
