Andy Tweedie Examples 0 Comments

Summary of the PZFlex HIFU Simulation The video demonstrates the acoustic solve for a High Intensity Focussed Ultrasound (HIFU) simulation. We generate the model from an imported tissue map of a human abdomen from the Visible Human Project. Calculating the thermal dose delivered by therapeutic treatments is dependent on many factors, and can be a complex process. PZFlex combines piezoelectric, acoustic, …
