Numerical simulation of an adaptive magnetic field source in magnetic drug targeted transport

While the magnetic field source used in magnetic drug targeting (MDT) therapy is usually a permanent magnet, planar spiral coils (PSC) prove to be equally effective. When properly designed, PSC may provide high magnetic field gradient configurations that result in larger magnetic body forces. To limit unwanted, side effects that may occur, e.g. the overheating of the adjacent tissue, PSCs may be powered either continuously or intermittently, and this makes the object of this work, where 2D numerical models are used to evaluate the heat transfer problem for different powering schemes, and 3D modeling is then utilized for a more realistic analysis.
