Patent ID: 8105307

Claim:
A computer implemented method for determining at least one infusion and/or injection region for infusing and/or injecting a medical drug into a heterogeneous body structure in order to achieve a distribution of the medical drug in a desired target region of the heterogeneous body structure, comprising: providing at least one property of the heterogeneous body structure that influences a spatial distribution of the medical drug in the heterogeneous body structure; determining, using a processor, the at least one infusion and/or injection region from which the medical drug is to be transported through the heterogeneous body structure to the at least one target region as a function of the at least one property of the heterogeneous body structure and a position of the desired target region, wherein the heterogeneous body structure is spatially divided into a plurality of segments and the probability of transport of the medical drug from one of said plurality of segments to another one of said plurality of segments is determined, said probability of transport determined based on percolation theory that includes calculating a probability of connection between adjacent segments to determine a percolation path; and outputting the at least one infusion and/or injection region via an output device.
