Presentation title: Ultrasonic surgery: Using sound to heal

Ultrasound is widely used to image inside the body; however it is also emerging as a therapeutic modality to treat certain medical conditions. In this talk some of the applications of therapeutic ultrasound will be presented, including: high intensity focused ultrasound (HIFU) to thermally ablate of localised regions of tissue in order to treat solid tumours;  the disruption of tissue (histotripsy) and fragmentation of kidney stones (lithotripsy) by means of shock waves; and the combination of ultrasound with microscopic drug carriers in order to deliver therapeutic drugs to specific locations in the body.  The talk will describe the underlying acoustic phenomena relevant to these applications and the interaction of sound with tissue through heating, cavitation and radiation. The opportunities and barriers to the wider adoption of sound to heal will be discussed.

Presentation title: The modelling of sound absorbing materials: Past, Present and Future

Porous materials are extensively used in industry to reduce noise and vibration annoyances in many industrial configurations. They are composed of a porous solid skeleton saturated by a fluid and they can dissipate energy through different mechanisms (viscosity and thermal effects in the fluid, structural damping in the skeleton).The objective of this presentation is to provide an overview of the physical models for porous materials. The first part of this talk will be devoted to classical homogeneous materials for which both constituents can be homogenised, and will then lead on to coupled models. Emphasis will be placed on the interaction between input parameters of the physical models and their associated characterisation techniques. A second part will present metaporous materials which correspond to porous materials with inclusions so as to enhance their dissipative properties.

Presentation title: Applications of photothermal and photoacoustic methods using different spatiotemporal excitation patterns

Photothermal and photoacoustic techniques exploit dynamical changes of temperature and strain patterns in materials in order to extract structural, thermal and elastic information. In the analysis, typically, the material properties are determined from the time or frequency dependence of the characteristic lengths of the involved thermal diffusion process (i.e., the thermal diffusion length) and acoustic wave propagation (i.e., the acoustic wavelength), which can be assessed from the spatial pattern of the temperature or strain. In this presentation, the methodology is illustrated for a variety of illumination patterns, both in time and frequency domain, for thermally, elastically and structurally characterize layers with thicknesses from the mm to sub-micron range.

Presentation title: The acoustic bubble

Gas bubbles in liquids have an extraordinary ability to interact with sound fields. Bubbles generate the song of a babbling brook, and ocean sounds that help us understand the global carbon budget. Particularly dense clouds of bubbles are produced in the ocean by humpback whales to form ‘bubble nets’ to catch prey; when dolphins do this, they must adapt their sonar to avoid the bubbles themselves preventing them from finding their prey using echolocation. Throughout industry and medicine, sound is used to activate bubbles, to generate a range of useful effects.
