Model Predictive Filtering MR Thermometry: Effects of Model Inaccuracies, k-Space Reduction Factor, and Temperature Increase Rate

摘要

Purpose: Evaluate effects of model parameter inaccuracies (thermal conductivity, k, and ultrasound power deposition density, Q), k-space reduction factor (R), and rate of temperature increase ((T) over dot) in a thermal model-based reconstruction for MR-thermometry during focused-ultrasound heating.
