Modeling a Focused Microwave System for Transcutaneous Thermal Therapy of Breast Cancer

J. Stang, B. Fowlkes, M. Moghaddam, O. Kripfgans, and P. Carson
University of Michigan, Ann Arbor, MI, USA

A transcutaneous thermal therapy system is being developed for the targeted treatment of breast cancer cells using focused microwaves as an adjuvant to surgery, radiation, chemotherapy, and high intensity focused ultrasound (HIFU). Prior imaging studies are used to ascertain the material properties of the breast tissue, and this data is incorporated into a COMSOL Multiphysics model. Time ...

Constructing Laser-Induced In Vitro Cell Damage Model Based on Thermal Analysis using COMSOL

The use of lasers in the military and everyday life is growing each year. The purpose of the current research is to take full advantage of this new spatially-resolved thermal data to construct a mathematical and numerical model for laser-induced damage using COMSOL Multiphysics. The microthermography data were extracted for vertical and horizontal lines through the laser-exposed area of cell ...

Effect of Calcification Properties on Stress in Models of Atherosclerotic Plaque

C. Buffinton, P. Rogerson, and D. Ebenstein
Bucknell University
Lewisburg, PA

The effects of calcifications on arterial wall stress have been largely ignored, in part because the material properties of the calcified areas were taken to be the same as the fibrous plaque, and in part because they are often assumed to have a stabilizing influence. Recent measurements suggest that their stiffness should be more similar to bone. A computational model is indicated for this ...
