Volume presentation for planning a location of an injection point

An image processing system for planning a location of at least one injection point for a medical procedure, the image processing system comprising:

• a data receiving module configured to receive at least one volume of imaging data for a region of interest;
• first and second rendering modules configured to render the at least one volume of imaging data;
• a processing module configured to obtain at least one virtual injection point indicating a location in a network of blood vessels for an injection;
• wherein the second rendering module renders imaging data at a higher level of detail than the first rendering module;
• wherein the processing module is configured to control the first and second rendering modules to construct a combined volume presentation including a first volume region rendered by the first rendering module and a second volume region based on imaging data at the higher level of detail rendered by the second rendering module, and
• wherein the processing module is configured to designate the first and second volume regions based on the at least one virtual injection point.
