Predictive modeling can play an important role in thermal ablative cancer treatments where estimated energy deposition may integrate into pre-operative planning software or combine with closed loop control. In this work, we develop a finite element model capable of simulating continuous rotation by a directional interstitial ultrasound applicator. The developed model simulates temperature maps for different rotation trajectories. The developed simulation was validated using magnetic resonance thermal imaging and demonstrated performance suitable for real-time control of robotically actuated conformal tumor ablation...

Blood perfusion plays a key role for the ablation success, especially in the case of highly vascularized organs like liver. Aim of this work is to evaluate the vessel distance influence on the thermal gradient and the cooling of the tissue caused by blood perfusion during laser ablation.
The proposed setup, based on Fiber Bragg Grating sensors (FBGs) around the laser applicator, permitted to measure the heat propagation and to observe a relevant tissue cooling near to the vessel...
