Telereconstruction from computerized tomography images for the distance teaching of medicine

A system for making remote two- and three-dimensional reconstructions from computerized tomography images has been developed in order to improve medical teleteaching. It allows the automatic two- and three-dimensional remote visualization of the anatomical structure of interest. As a part of this system, software has been developed which allows many visual operations or transformations on a remote three-dimensional model. It permits the remote workstation and the local workstation to visualize every transformation simultaneously. It allows a doctor to interact virtually and remotely with the anatomical structure. The software enables examination of the anatomical model from all angles, even from inside (including planar and three-dimensional presentations).

New Approach

Three-dimensional computerized tomography provides a new approach to radiological imaging. Raw data from sequential two-dimensional scans have been reconstructed as a three-dimensional model of the carpal area using the Medical Graphics and Imaging Workstation. This study demonstrates the anatomical accuracy and potential diagnostic qualities of a reconstruction of the carpus using this system. The advantages, pitfalls and suggested applications of this technique of carpal imaging are discussed. Three-dimensional imaging is shown to provide a great deal of information which cannot be viewed on conventional radiographs or CT images.

Remote User

We have developed a system for remote three-dimensional reconstruction, which facilitates telediagnosis. The telereconstruction system is based on a computerized tomography (CT) scanner, a workstation connected to the CT scanner, a PC, which can be geographically far away from the workstation, and a computer program that we have developed. The workstation allows CT images to be stored and image processing to be carried out. The PC permits the user to control the workstation in making a three-dimensional reconstruction and allows the remote user to see that reconstruction. From the PC various graphical operations can be performed on the three-dimensional model, such as rotations, translations and cuts through the model. The program therefore allows a remote user to have three-dimensional images and to study them by means of all the options the program provides.
