Effects of Geometry Discretization Aspects on the Numerical Solution of the Bioheat Transfer Equation with the FDTD Technique

Theodoros Samaras, Andreas Christ, and Niels Kuster, in Physics in Medicine and Biology, Volume 51, No. 11, pp. N221–N229, May 2006

In this work, two issues are highlighted that have to be taken into consideration for accurate thermal modeling with the finite-difference time-domain (FDTD) method, namely the tissue interfaces and the staircasing effect. The former appears less critical in the overall accuracy of the results, whereas the latter may result in significant underestimation of the actual thermal load.
