Special Issue Information

Dear Colleagues,

We would like to present the very latest progress in acoustics, vibrations, and fluid–structure interactions techniques that would be a beneficial for sound analysis in biomedical applications. For biomedical applications, there are many situations such a listening to the blood flow through patients' heart valves from the chest/skin, or listening to the air flow in patients' lung airways with different levels of stenosis. In these cases, air and blood turbulent flows exist in a flow-bounded domain which interact with solid rigid/elastic/moving bodies like mechanical heart valves or tumors in lung airways.

Our aim is to publish studies that reveal how mechanical vibration and sound impact the design and performance of engineered medical devices and improve non-invasive monitoring, analysis and diagnostic techniques of biological systems. This Special Issue: “Acoustics in Biomedical Engineering”, covers research results involving the application of mechanical and electrical engineering principles with a focus on developments in numerical methods and experimental techniques. “Acoustics in Biomedical Engineering” publishes original research and review articles in a wide range of topics including, but not limited to:

  • Cardiovascular and respiratory biomechanics: mechanics of blood-flow, air-flow, mechanics of the soft tissues, flow-tissue or flow-prosthesis interactions
  • Computational methods for analyzing the performance of medical devices, artificial organs, and prostheses
  • Bioacoustics and sound in biological systems
  • Biomedical signal processing and medical device development
  • Structural acoustics and vibration
  • Engineering acoustics, sound transducers, and measurements
  • Fluid-structure Interactions and Flow-induced vibration
  • Acoustic Signal Processing

Many biomedical applications such as ultrasonic targeted drug delivery, gene therapy, and molecular imaging entail the problems of manipulating microbubbles by means of a high-intensity focused ultrasound (HIFU) pressure field; namely stable cavitation. In high-intensity acoustic field, bubbles demonstrate translational instability, the well-known erratic dancing motion, which is caused by shape oscillations of the bubbles that are excited by their volume oscillations. The literature of bubble dynamics in the HIFU field is mainly centered on experiments, lacking a systematic study to determine the threshold for shape oscillations and translational motion. In this work, we extend the existing multiphysics mathematical modeling platform on bubble dynamics for taking account of (1) the liquid compressibility which allows us to apply a high-intensity acoustic field; (2) the mutual interactions of volume pulsation, shape modes, and translational motion; as well as (3) the effects of nonlinearity, diffraction, and absorption of HIFU to incorporate the acoustic nonlinearity due to wave kinematics or medium—all in one model. The effects of acoustic nonlinearity on the radial pulsations, axisymmetric modes of shape oscillations, and translational motion of a bubble, subjected to resonance and off-resonance excitation and various acoustic pressure, are examined. The results reveal the importance of considering all the involved harmonics and wave distortion in the bubble dynamics, to accurately predict the oscillations, translational trajectories, and the threshold for inertial (unstable) cavitation. This result is of interest for understanding the bubble dynamical behaviors observed experimentally in the HIFU field. Full article
