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.
