Trust-region versus line search globalization strategies for inexact Newton method and application in full waveform inversion

Qinglong He et al.

Summary: In this study, the inexact Newton method using trust-region and line search globalization strategies is considered for solving the large-scale full waveform inversion problem. A stopping criterion and forcing term are introduced to prevent oversolversion of the Newton equation. An efficient method is developed to compute (pseudo) Hessian vector products, and a diagonal preconditioner based on the pseudo-Hessian approach is employed to accelerate the Newton equation solution. Numerical experiments on various models demonstrate that the trust-region method performs better than the line search globalization strategy, especially for high contrast velocity models.

DESIGN AND CONSTRUCTION OF A LOW-FREQUENCY ULTRASOUND ACQUISITION DEVICE FOR 2-D BRAIN IMAGING USING FULL-WAVEFORM INVERSION

Javier Cudeiro-blanco et al.

Summary: The main techniques used for brain imaging and structural data are magnetic resonance imaging and X-ray computed tomography. However, these techniques have limitations such as requiring large equipment and using ionizing radiation. This study explores the potential of using full-waveform inversion, originally from Earth science, to generate accurate 3-D images of the brain using ultrasound imaging. The researchers designed a device with an annular array of ultrasound transducers and successfully reconstructed images of the brain with millimeter resolution.

Comparison Between Ray-Tracing and Full-Wave Simulation for Transcranial Ultrasound Focusing on a Clinical System Using the Transfer Matrix Formalism

Thomas Bancel et al.

Summary: At present, only one high-intensity focused ultrasound device has been clinically approved for transcranial brain surgery. It corrects phase distortions induced by the skull using a multielement phased array and adaptive phase correction based on CT images. The performance of the clinical device's phase correction was assessed and compared with other correction methods, showing different results based on incident angles of the acoustic beam at the skull surface.
