3-D-DOCTOR is 3-D imaging software for researchers doing medical (MRI, CT, Microscopy), engineering, scientific, and industrial 3-D imaging applications. It is US FDA-approved for medical imaging applications. The software creates 3-D surface models and volume rendering from 2-D cross-section images (in DICOM, BMP, RAW, TIFF, JPEG, PNG, GIF or other format) and exports 3-D polygon models to DXF, 3-DS, STL, IGES, VRML, XYZ, and other formats. Its vector-based technologies support easy image data handling, measurement, and quantitative analysis. Import Image File Formats include DICOM, TIFF, BMP, JPEG, Interfile, PNG, Raw Image Data, and other uncompressed image formats. Image files in various vendor specific formats can be read using the universal image configuration and input function.
