A method of processing medical imaging volume data in a computer network is described. The method comprises loading a medical imaging data set to be processed to a server computer, processing the data set on the server computer, e.g. by executing a software application, and generating corresponding server-generated results. The server-generated results, e.g. rendered images, may then be transmitted to a client computer for display to a user. This allows users to quickly view the results of the processing because they have not had to wait for the data set to be transferred to their local machine before locally processing the data. However, while this is happening, the data set itself is also transmitted, e.g. as a background operation, to the client computer. Thus eventually the client computer has access to a local copy of the data set and may start processing the data set itself, thus freeing up server resources.
