  • Title: Discrete vessel heat transfer in perfused tissue--model comparison.
    Author: Stańczyk M, Van Leeuwen GM, Van Steenhoven AA.
    Journal: Phys Med Biol; 2007 May 07; 52(9):2379-91. PubMed ID: 17440241.
    Abstract:
    The aim of this paper is to compare two methods of calculating heat transfer in perfused biological tissue using a discrete vessel description. The methods differ in two important aspects: the representation of the vascular system and the algorithm for calculating the heat flux between tissue and blood vessels. The first method was developed at the University of Utrecht between 1994 and 1998 and has been used in several clinical applications. The second method has been proposed by the first author. The methods are briefly described, their assumptions and limitations are discussed. Finally, the test simulation is introduced and the results produced by both methods are compared. The test indicates that the simpler, and less computationally intensive method proposed by the present author for calculating 2D problems containing countercurrent blood vessel systems can reproduce quite well some features of the solution obtained by the more complex 3D method. The observed discrepancies could be explained on physical grounds.
