An apparatus determines an injection point for targeted drug delivery into a patient's body by injection of the drug into a vessel feeding a target area including a target. To provide the interventionalist with an objective and quantitative assessment of potential drug injection points instead of letting him rely on his subjective impression from the visual inspection of DSA sequences, a processor (4) includes an identification routine (41) for identification of a vessel tree topology of vessels feeding the target area, a flow determination routine (42) for determining the percentage of drug material delivered to said target after injection into different potential injection points in the vessel tree, a selection routine (43) for selecting as optimal injection point the potential injection point resulting in the highest percentage of drug delivery to the target. |
