RISReconstruction of Experimental Hyperthermia Temperature Distributions: Application of State and Parameter Estimation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Subsets of data from spatially sampled temperatures measured in each of nine experimental heatings of normal canine thighs were used to test the feasibility of using a state and parameter ...
A Comparative Evaluation of Unconstrained Optimization Methods Applied to the Thermal Tomography Problem
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In cancer hyperthermia treatments, it is important to be able to predict complete tissue temperature fields from sampled temperatures taken at the limited number of locations allowed by clinical ...
Estimating Three-Dimensional Temperature Fields During Hyperthermia: Studies of the Optimal Regularization Parameter and Time Sampling Period
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During hyperthermia therapy it is desirable to know the entire temperature field in the treatment region. However, accurately inferring this field from the limited number of temperature measurements ...
Dynamic Contrast-Enhanced MRI and Fractal Characteristics of Percolation Clusters in Two-Dimensional Tumor Blood Perfusion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dynamic contrast-enhanced magnetic resonance imaging (DE-MRI) of the tumor blood pool is used to study tumor tissue perfusion. The results are then analyzed using percolation models. Percolation ...
