Embodiment Construction

[0055] The present invention provides a method and system for transferring graphics data from a first device to at least one second device in a computer network system. The invention is described below with reference to a preferred embodiment in which the graphical data is graphical medical data and the computer network system is a client / server system. Figure 1 gives a schematic diagram.

[0056] Medical image data is obtained with a medical scanner 1 connected to a server computer 2 . A large number of clients 3 can connect to this server. This server is part of the PACS system. When a patient has undergone a scan, the images 16 obtained may be automatically or manually transmitted to and stored on the server device. Although only reference is made to a server or server device, the server can be a single computer, a cluster of computers, or a system of computers connected by a computer connection. Access to the image can be established at any time thereafter. In additio...

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. Based on the estimated available bandwidth, the generated screen image is compressed using a corresponding compression method so that a compressed screen image is formed. The screen image may also be encrypted. The compressed (and possible encrypted) screen image is forwarded (22) to the client, and shown on the screen of the client (23). The compression method depends foremost upon the available bandwidth, however also the type of client machine (28), the type of request, etc. may be taken into account.

Description

technical field [0001] The present invention relates to methods and systems for remote display and data analysis of graphical data, and more particularly, the present invention relates to remote display and data analysis of graphical medical data. Background technique [0002] A wide variety of medical image scanners have been developed in order to visualize various internal features of the human body, such as the location of tumors. Volumetric scanners, i.e. 3D scanners, such as computed tomography (CT), magnetic resonance imaging (MRI), ultrasound (US), electron emission tomography (PET) and single photon emission computed tomography (SPECT) as well as 2D scanners , such as computed radiography (CR) and digitally controlled radiography (DR) are available. Scanners use different biophysical mechanisms to generate images of the human body. For example, CT scanners detect X-ray absorption in a specific volume of the scanned patient, while MRI scanners use magnetic fields to...
