An Angular Spectrum Method for Nonlinear Propagation in Heterogeneous Tissue with Immersed Sources for Ultrasound
Gianmarco Pinton
A modified angular spectrum method (ASM) is developed for three-dimensional nonlinear acoustic propagation through heterogeneous tissue, targeting transcranial and therapeutic ultr…
An open-source framework for predicting ultrasound neuromodulation: bridging tissue elastomechanics and neuron firing dynamics
Gianmarco Pinton
Transcranial focused ultrasound is a non-invasive neuromodulation modality with millimetre-scale resolution, but its biophysical mechanism of action remains unresolved. Exposure is…
A reduced viscoelastic FDTD formulation for ultrasound-driven shear wave propagation in soft tissue
Gianmarco Pinton
The paper introduces a reduced viscoelastic finite-difference time-domain (FDTD) method that efficiently models ultrasound‑driven shear wave propagation in soft tissue, focusing on…
IQ-JEPA: A Joint-Embedding Predictive Architecture with a Hermitian Vision Transformer for Sound Speed and Attenuation Estimation from Ultrasound IQ Data
Masashi Sode, Gianmarco Pinton
The speed of sound in tissue is a prerequisite for well-focused imaging and has diagnostic value, but recovering it from raw pulse-echo channel data is fundamentally a nonlinear in…
Spatially heterogeneous power-law attenuation with multiple relaxation mechanisms for ultrasound modeling
Masashi Sode, Gianmarco Pinton
Objective. The soft tissue attenuation laws have a magnitude and frequency dependence that varies across tissue types and generally follow power laws. An accurate model of ultrasou…
mach: ultrafast ultrasound beamforming
Charles Guan, Alexander P. Rockhill, Masashi Sode +1
Purpose: Volumetric ultrafast ultrasound produces massive datasets with high frame rates, dense reconstruction grids, and large channel counts. Beamforming computational demands li…
