Harmonic motion imaging for focused ultrasound (HMIFU) utilizes an amplitude-modulated HIFU beam to induce a localized focal oscillatory motion simultaneously estimated. The objective of this study is to develop and show the feasibility of a novel fast beamforming algorithm for image reconstruction using GPU-based sparse-matrix operation with real-time feedback. In this study, the algorithm was implemented...
Harmonic Motion Imaging (HMI) is a technique capable of imaging tissue mechanical properties during acoustic radiation force application. Recently, HMIFU has been shown capable for high-intensity focused ultrasound (HIFU) therapy and monitoring. Here, a theoretical analysis of the Harmonic Motion Imaging for Focused Ultrasound (HMIFU) system is performed using a 2D nonlinear wave propagation model...
