Iterative curve fitting of the bioheat transfer equation for thermocouple-based temperature estimation in vitro and in vivo.
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control(2020)
摘要
Temperature measurements with thin thermocouples embedded in ultrasound fields are strongly subjected to a viscous heating artifact (VHA). The artifact contribution decays over time; therefore, it can be minimized at late temperature readings. However, previous studies have failed to demonstrate a rigorous method for determining the optimal time point at which the artifact contribution is negligib...
