A signal processor circuit comprising a rendering module for rendering images from respective patient multidimensional imaging data sets obtained from different imaging modalities, wherein the circuit is configured to communicate with a graphical user interface associated with a client workstation to accept user input to define at least one explicit prioritized feature in an image rendered from a multi-dimensional image data set, wherein the at least one prioritized feature is automatically electronically rendered with high or full quality in different interactively requested rendered images of the image data while non-prioritized features are rendered at lower quality.
