The Medical Working Group for X3D develops and demonstrates open interoperable standards for the representation of human anatomy based on a wide variety of imaging modalities.

This member-only working group meets when necessary and discussions occur on the med mailing list. Web3D Calendar

The Medical Working Group is developing an open interoperable standard for the representation of human anatomy based on input from a wide variety of imaging modalities. This will allow manufacturers of imaging equipment to export an interoperable file format that can be used both by physicians and students on their desktop computers. Radiologists and physicians can give the patient CD-ROMS of their scans which they can view in the privacy of their homes. If a patient has undergone multiple types of scans (CAT, MRI, PET) these may all be viewed and registered giving the physician and patient a clearer view of the underlying issues. Researchers can take the exported data from many different types of equipment and fuse them into a coherent 3D data set that can be used both for patient education, diagnostics and surgical training.

MedX3D is tightly focused on medical applications that can benefit from real time 3D visualization. These types of applications include medical modeling and simulation for research and education; 3D image rendering for planning and guiding surgical and nuclear medicine procedures; image fusion-the association of specific 2D images from multimodal (PET, CAT, MRI, Ultrasound) scans with one another or with existing 3D images of a given patient.

We are also working to develop interchange mechanisms between Digital Imaging and Communication in Medicine (DICOM) and MedX3D.

Application Areas:

  • Medical Modeling
  • Surgical training
  • Patient education

Technical Focus:

  • Representation of human anatomy in X3D
  • Association of 2D images (from multiple modalities) with 3D skeletal structure with registration
  • Extension of X3D to accommodate image textures in context of 3D anatomy model
  • 3D Printing and Scanning
