Abstract: A method and system for sharing intermediate medical image processing results among several different applications is disclosed. An application server serves as mediator between a medical image database storage, image processing applications, and a workstation display resident on a computer network. The application server polices the intermediate processing results from several different image processing applications in order for the image processing applications to share their intermediate results. By sharing the intermediate results, the application server helps to eliminate duplicate processing and inconsistent results between the image processing applications. The final image processing results are either stored on the medical image database or displayed on the workstation as needed. The image processing applications could reside on the application server or on their own separate networked computer.
