Abstract

A system for viewing at a client device a series of three-dimensional virtual views over the Internet of a volume visualization dataset contained on centralized databases employs a transmitter for securely sending volume visualization dataset from a remote location to the centralized database, more than one central data storage medium containing the volume visualization dataset, and a plurality of servers in communication with the centralized databases to create virtual views based on client requests. A resource manager load balances the servers, a security device controls communications between the client device and server and the resource manager and central storage medium. Physically secured sites house the components. A web application accepts at the remote location user requests for a virtual view of the volume visualization dataset, transmits the request to the servers, receives the resulting virtual view from the servers, and displays the resulting virtual view to the remote user.

Claims

1. A system for viewing at a client device at a remote location a series of virtual views over the Internet of a medical imaging dataset contained on at least one remote and centralized database comprising:

at least one transmitter for accepting the medical imaging dataset from an image originating source and transmitting it securely to the database;

a first security device controlling the plurality of communications between the transmitter and the database;

at least one data storage medium containing the medical imaging dataset;

a plurality of servers in communication with the at least one database and capable of processing the medical imaging dataset to create virtual views based on a client request;

the first or a secondary security device controlling the plurality of communications between a client device and the server, including storage medium and database;

at least one physically secured site for housing the database, at least one data storage medium, the plurality of servers, and first and secondary security devices, the at least one physically secured site remote from the image originating source; and

a web application adapted to satisfy a user'"'"'s request for the virtual views by;

a) accepting at a remote location at least one user request for a series of virtual views of the medical imaging dataset, the series of views comprising a plurality of separate view frames, the remote location having a local data storage medium for storing frames of views of the medical imaging dataset, b) transmitting from the remote location to at least one of the servers a request for any frame of the requested views not stored on the local data storage medium, c) at at least one of the servers, creating the requested frames of the requested views from the medical imaging dataset in the storage medium, d) transmitting the created frames of the requested views from at least one of the servers to the client device, e) receiving and storing on the local data storage medium the requested views from the at least one server, and f) displaying to the user at the remote location the requested series of virtual views of the medical imaging dataset by sequentially displaying frames transmitted from at least one of the servers along with any frames of the requested series of views stored on the local data storage medium.

2. The system of claim 1 wherein the web application is adapted to select a secured site by using a domain name address on a web browser.

3. The system of claim 1 wherein the web application is adapted to be authenticated using an authorized user credentials prior to transmitting the request to at least one of the servers.

4. The system of claim 3 wherein an authenticated web application lists the medical imaging datasets that are viewable by the authorized user.

5. The system of claim 4 wherein the web application initiates a virtual viewing by selecting a medical imaging dataset.

6. The system of claim 1 further including an encrypted communication connection over which the request and the resulting virtual view are transmitted.

7. The system of claim 1 wherein a secured site is an audited or tested premises.

8. The system of claim 1 wherein multiple secured sites located in disparate physical locations are connected via an Internet or an Intranet.

9. The system of claim 8 wherein the multiple secured sites offer distributed data processing capabilities.

10. The system of claim 1 wherein the web application communication with one of the plurality of servers is via a web application programming interface.

11. The system of claim 1 wherein, for each view request, the web application determines location of the stored frame of the prior request of the virtual view on the local data storage medium, and uses such location to display the stored frame if one exists.

12. The system of claim 1 wherein the web application causes the remote location to display higher image quality parameter frames after completing display of lower image quality parameter frames.

13. The system of claim 1 wherein the web application causes the server to transmit the frames to the remote location as a compressed video stream.

14. The system of claim 1 wherein the web application causes the server to transmit the frames to the remote location as one or more single frames.

15. A method for viewing at a client device at a remote location a series of virtual views over the Internet of a medical imaging dataset contained on at least one remote and centralized database comprising:

providing at least one data storage medium containing the medical imaging dataset;

providing at least one server in communication with the at least one database and capable of processing the medical imaging dataset to create virtual views based on client request;

providing a web application accessible at a client device linked to the at least one server and storage medium over the Internet, the client device having local data storage medium for storing frames of views of the medical imaging dataset, the web application adapted to perform the steps of;

requesting at the client device a series of virtual views of at least a portion of the medical imaging dataset, the series of views comprising a plurality of separate view frames;

determining if any frame of the requested views of the medical imaging dataset is stored on the local data storage medium;

sending from the client device to the server a request for any frame of the requested views;

at the server, creating the requested frames of the requested views from the medical imaging dataset;

transmitting the created frames of the requested views from the server to the client device;

storing the received frames of the requested views on the client device local data storage medium; and

displaying the requested series of virtual views of the medical imaging dataset at the client device by sequentially displaying frames transmitted from the server along with any frames of the requested series of views stored on the local data storage medium.

16. The method of claim 15 wherein, for each view request, the client device determines location of the stored frame of the prior request of the virtual view on the local data storage medium, and uses such location to display the stored frame if one exists.

17. The method of claim 15 wherein the client device displays higher image quality parameter frames after completing display of lower image quality parameter frames.

18. The method of claim 15 wherein the frames are transmitted from the server to the client device as a compressed video stream.

19. The method of claim 15 wherein the frames are transmitted from the server to the client device as one or more single frames.

20. The method of claim 15 wherein the client device communication with one of the plurality of servers is via a web application programming interface.
