Abstract

An image processing system using volume data comprising at least one node connected via a network, which is operative to monitor completion of a task property storing condition for storing a task property of a client terminal, collect the task property of a task state of the client terminal and store the collected task property in a state storing server when the task property storing condition is satisfied, read the task property which corresponds to the client terminal from the state storing server, restore the task state of the client terminal by using the read task property in a proxy node which is at least any one of the node and a node which is newly added to the image processing system, and resume processing to be performed on and after the time when the task property storing condition is satisfied.

Claims

1. An image processing system using volume data comprising at least one node connected via a network which includes a client terminal, a state storing server, an image processing server and a data server, said image processing system being operative to:

monitor satisfaction of a task property storing condition for storing a task property of the client terminal;

collect said task property of a task state of the client terminal and store the collected task property in the state storing server when said task property storing condition is satisfied;

read said task property which corresponds to the client terminal from the state storing server;

restore said task state of the client terminal by using the read task property in a proxy node which is at least any one of said node and a node which is newly added to said image processing system; and

resume processing to be performed on and after the time when said task property storing condition is satisfied.

2. The image processing system as claimed in claim 1, wherein said task property includes at least one of a window layout, an image type, an user defined caption, a diagnosis result, a camera position, a camera type, a camera angle, a magnifying scale power of a camera, an operating system level information, an operating system version information, a mask and region extraction information, a path information representing a vessel course and the like, an additional information map provided by an image analysis, a necessary information for generating a same image as an image when the task property of the client terminal is stored, information on the node which processed the task such as an identifier and processing capability of the node, an identifier of image source data being processed, a user name, a processing date and time, an additional information, an information indicating intermediate step of calculation, and a patient information.

3. The image processing system as claimed in claim 1, wherein said proxy node is operative to select at least one image processing server from said node for restoring the :

task state of the client terminal.

4. The image processing system as claimed in claim 3, wherein said proxy node is operative to inquire of said image processing server whether the image processing server holds an image source data which can be used for restoring the task state of the client terminal so as to select said at least one image processing server.

5. The image processing system as claimed in claim 1 further being operative to monitor a calculation resource amount which includes at least any one of a current load state, a performance record, a status, a performance specification and a distance on the network of said at least one node respectively.

6. The image processing system as claimed in claim 1, wherein said image processing server is capable of assigning the processing of said image processing server to at least one other image processing server.

7. The image processing system as claimed in claim 1, wherein at least any one of volume rendering processing, region extraction processing, image filtering processing, noise removal processing, image fusion processing, perfusion calculation processing, back projection processing, projection processing and geometry transform processing is performed.

8. The image processing system as claimed in claim 1, wherein said task property storing condition includes at least any one of non-existence of command for a certain amount of time, every expiration of a certain amount of time, when the client terminal enters a specific state, when the state storing server enters a specific state, when an explicit command is received from the client terminal, when the client terminal is paused, and when the user exits task involved in the image source data.

9. The image processing system as claimed in claim 1, wherein the client terminal comprises a plurality of client terminals, and said task property storing condition is further satisfied for the client terminal with low priority when the client terminal with high priority exists in the system and a load on the system is high.

10. The image processing system as claimed in claim 1, wherein at least any one of a termination of the client terminal and a release of the image processing server is performed when said task property storing condition is satisfied.

11. The image processing system as claimed in claim 1, wherein said image processing server acquires an image source data from said data server when the processing is resumed.

12. A method for performing image processing using volume data having at least one node connected via a network, said method comprising:

monitoring satisfaction of a task property storing condition for storing a task property of a client terminal;

collecting said task property of a task state of the client terminal and storing the collected task property in a state storing server when said task property storing condition is satisfied;

reading said task property which corresponds to the client terminal from the state storing server;

restoring said task state of the client terminal by using the read task property in a proxy node which is at least any one of said node and a node which is newly added; and

resuming processing to be performed on and after the time when said task property storing condition is satisfied.
