Abstract

A new algorithm for simultaneously identifying the space or temperature dependent conductivity K, blood perfusion rate Wb, metabolic rate qm, and thermal diffusibility alpha in Pennes' equation is postulated. The obtained over determined equations are solved by way of Householder's transformation. The validity of the method is tested through an example.

摘要

提出了一种新算法，用于同时识别彭尼斯方程中与空间或温度相关的电导率K、血液灌注率Wb、代谢率qm和热扩散率α。通过豪斯霍尔德变换求解得到的超定方程组。通过一个例子验证了该方法的有效性。
