Abstract

In this paper, we describe a Medical Image Information System. Our system stores and manages 3 dimensional medical image data and provides the 3 dimensional medical data via the Internet. The Internet standard VR format, VRML(Virtual Reality Modeling Language) is used to represent the 3D medical image data. The 3D images are reconstructed from medical image data which are generated by medical imaging systems such as CT(Computerized Tomography), MRI(Magnetic Resonance Imaging), PET(Position Emission Tomography), SPECT(Single Photon Emission Computed Tomography). We implemented the medical image information system which uses a surface-based rendering method for the reconstruction of 3D images from 2D medical image data. In order to reduce the size of image files to be transferred via the Internet. The system can reduce more than 50% for the triangles which represent the surfaces of the generated 3D medical images. When we compress the 3D image file, the size of the file can be reduced more than 80%. The users can promptly retrieve 3D medical image data through the Internet and view the 3D medical images without a graphical acceleration card, because the images are represented in VRML. The image data are generated by various types of medical imaging systems such as CT, MRI, PET and SPECT. Our system can display those different types of medical images in the 2D and the 3D formats. The patient information and the diagnostic information are also provided by the system. The system can be used to implement the "Tele-medicine" systems.
