![]() The mean shape error between software packages of the mandibular STL model was 0.11 mm, but there was no statistically significant difference between them. Our results revealed that there are some differences between the software packages that perform the segmentation and STL creation of the DICOM image data. ![]() In particular, the features of each software package appeared in the fine and thin areas of the osseous structures. When using these software packages, it is necessary to understand the characteristics of each.ĭigital Imaging and Communications in Medicine (DICOM) is the leading standard around the world within the medical imaging information field. Three-dimensional (3D) printing from DICOM images has become easier with the advancement of technologies such as medical engineering, imaging engineering, and the evolution and decreasing costs of hardware and software. Patient-specific 3D models are now being used in many situations within the oral and maxillofacial surgery fields, including education, surgical planning, and surgical simulation. ģD printing of DICOM images works with stacked 2D images that must be segmented to a data format required by the 3D printer. For this purpose, DICOM images are now being segmented to a 3D computer-aided design (CAD) format for intermediate data, on which primary processing, such as region of interest (ROI) setting, can be performed. Of the approximately 100 file formats of 3D CAD data that are used as 3D native files and intermediate files, a stereolithography (STL) file format is the most commonly used format for 3D printing. ![]() There are many commercial (fee-based) and open-source (free-of-charge) software packages for segmenting DICOM images to STL data, all of which can run on a general-purpose personal computer (PC). ![]() #OSIRIX LITE REMOVE NOT FOR MEDICAL USAGE SOFTWARE# #OSIRIX LITE REMOVE NOT FOR MEDICAL USAGE SOFTWARE#.
