Abstract: The invention relates to simulating 2D X-ray images from 3D CT data. A user can access a repository of CT data of a patient's anatomy 2 by using a computer network system. The CT data has been obtained by a CT scanning of the patient 1. Firstly, the user retrieves the CT image data 3 and a 3D image is generated 4. Secondly, the user may orient the CT image in any orientation desirable with respect to a virtual X-ray source and a virtual image plane. And thirdly, a 2D X-ray image is simulated 6 from the chosen viewpoint and shown to the user.

Abstract: The invention relates to a method and system for remote visualization and data analysis of graphical data, in particular graphical medical data. A user operates a client machine 21 such as a thin client, a PC, a PDA, etc. and the client machine is connected to a server machine 20 through a computer network. The server machine runs an adaptive streaming module (ASM) which handles the connection between the client and the server. All data and data applications are stored and run on the server. A user at the client side requests data to be shown on the screen of the client, this request 24 is transferred to the server. At the server side the request is interpreted as a request for a particular screen image, and a data application generates the requested screen image and estimates a present available bandwidth 26 of a connection between the client and the server.
