Passive Acoustic Mapping of Cavitation in Heterogeneous Speed of Sound Distributions using the Fast Marching Method
Abstrak
Passive Acoustic Mapping (PAM) is a technique used to localize cavitation events in biomedical applications such as targeted drug delivery, histotripsy, and lithotripsy. Accurate cavitation mapping is essential for optimizing therapeutic efficacy and safety. However, conventional PAM assumes a homogeneous speed of sound within tissue, which does not reflect the heterogeneous acoustic properties of biological media. In this work, we introduce the Fast Marching Method (FMM) to PAM for accurately computing time delays in arbitrary speed of sound distributions. We evaluate the proposed approach through simulations, demonstrating its potential for improved cavitation mapping in realistic tissue environments.
