Ultrasounds are widely used in several industries and use cases, like the nondestructive testing (NDT) of metallic parts or for medical imaging, one famous example being echography.
The advantage of ultrasounds is being able to reach a volume inside matter without affecting the surface and what is between the surface and the zone of interest.
In the medical technology (medtech) industry, high-intensity focused ultrasound (HIFU) surgical tools are designed based on focused ultrasounds and produce a localized elevation of temperature and necrosis of biological tissues, for instance, for the treatment of some types of cancer.
Simulating the acoustics and heat transfer phenomena involved in such tools allows engineers and researchers to select the combination of parameters that will deliver the right amount of energy in the targeted zone and limit the damage to the surrounding healthy tissues. There are numerous parameters, including the size of the transducer that transmits the ultrasounds, the frequency of the signal, and the duration of the treatment.
In this presentation, Thomas Clavet from EMC3 Consulting will discuss how HIFUs can be produced and key points about how to model this multiphysics problem.
Thomas Clavet, Principal Engineer, EMC3 Consulting
Thomas Clavet founded EMC3 Consulting in February, 2014, to support companies (including SMEs, major industrial groups, and research laboratories) in their use of digital simulation for acoustics, thermal, mechanical, and flow (CFD) applications. Prior to becoming a COMSOL Certified Consultant, Thomas was a mechanical engineer in the nuclear industry and an applications engineer at COMSOL in the UK and Ireland, where he was able to meet many COMSOL Multiphysics® users from a variety of backgrounds and industrial sectors. Thomas is an Arts et Métiers ParisTech engineer and holds a master's degree in mechanics and numerical methods from the Royal Polytechnic Institute (KTH) in Stockholm, Sweden.
