Abstract: This study presents a new approach for evaluating bioheat transfer equation (BHTE) models used in treatment planning, control and evaluation of all thermal therapies. First, 3D magnetic resonance temperature imaging (MRTI) data are used to quantify blood flow-related energy losses, including the effects of perfusion and convection. Second, that information is used to calculate parameters of a BHTE model; in this paper the widely used Pennes BHTE. As a self-consistency check, the BHTE parameters are utilized to… Show more

“…Some degree of heterogeneity exists in all tissues and may affect the property determination results. Property mapping techniques may be appropriate [24,25,30]. More significant may be the assumption of constant tissue properties during the heating and cooling periods analysed from each sonication.…”

“…Several methods have been developed for using MRgFUS temperature data to non-invasively determine thermal diffusivity [23][24][25][26][27][28] and the Pennes perfusion parameter [23][24][25][26][28][29][30]. Of these methods, the one presented by Dillon et al in 2016 [28] is unique in that it simultaneously identifies thermal diffusivity and the Pennes perfusion parameter by fitting an analytical solution to the heating and cooling MR temperature data.…”

“…At present, satisfactory results have been obtained for the clinical treatment of liver cancer, prostate cancer, pancreatic cancer, osteosarcoma, and uterine fibroids 2 . However, the ultrasonic energy would be attenuated with the increased propagation distance 3 , and the heat would be absorbed by the blood flow 4 . In addition, any bone or gas barrier along the acoustic beam path would also weaken the energy accumulation in the target area 5,6 .…”

“…Blood flow provides up to 90% of heat removal. A 10-fold increase in blood flow in response to LHT can occur due to the compensatory expansion of arteries and intensive perfusion, especially in normal tissues [64][65][66].…”
