Computational and Experimental Modeling of the Bioheat Transfer Process of Perfusion in Tissue Applied to Burn Wounds
A new mathematical model has been developed along with a new parameter estimation routine using surface temperature and heat flux measurements to estimate blood perfusion and thermal resistance in living tissue. Dynamic thermal measurements collected at the surface of the sensor before and after …

Analysis of Power Deposition Patterns and Ultrasonic Phased Arrays for Localized Hyperthermia
… by using a finite difference solution to the bioheat transfer equation. The combination of these two methods allows calculation of temperature distributions produced by a given applicator design.

NUMERICAL AND EXPERIMENTAL INVESTGIATION OF CRYO-FREEZING WITH LARGE BLOOD VESSELS
… to the blood flow in the vessel embedded in the bioheat transfer equation significantly impacts the tissue temperature profiles and thermal gradient histories. The effects of the blood vessel structure and injected nanoparticles on the cryo-freezing of a clinically-extracted vascular tissue are …

A 3-Dimensional In Silico Test Bed for Radiofrequency Ablation Catheter Design Evaluation and Optimization
… the laminar fluid flow, electrical currents, and bioheat transfer was used to simulate radiofrequency (RF) tissue ablation. Simulations in simplified 3D geometries led to lesions sizes within the reported ranges from an<em> in-vivo</em> ablation study. However, though the ellipsoid lesion …

Incorporating Magnetic Nanoparticle Aggregation Effects into Heat Generation and Temperature Profiles for Magnetic Hyperthermia Cancer Treatments
… at 43 textcelsius~model is used. The Pennes bioheat equation is used as the governing equation for the temperature rise and included in it is a source heating term due to the NPs. NP diffusion and aggregation are simulated via a random walk process, with a probability of aggregation …

Nanoscale thermal transport for biological and physical applications
… during MFH is investigated through a bioheat transfer relation which indicates that the P\'eclet, Joule, and Fourier numbers are the more influential parameters that determine the heating during such a thermotherapy. Thus, we show that a fundamental parametric investigation of the …

Use of Bioheat Modeling to Characterize and Optimize Implantable Medical Devices and Neuromodulation Technologies
… The purpose of this work was to: (1) develop a bioheat FEM model to characterize joule heating during Spinal Cord Stimulation; (2) develop and validate a time-dependent adaptive bioheat model of therapeutic brain cooling device. We employed both technical and experimental methods in achieving …
