Dual-Probe Transcranial Full-Waveform Inversion: A Brain Phantom Feasibility Study.

ABSTRACT:

Objective

Despite being a low-cost, portable and safe medical imaging technique, transcranial ultrasound imaging is not used widely in adults because of the severe degradation and distortion of signals caused by the skull. Full-waveform inversion (FWI) has recently been found to have potential as an effective method for transcranial ultrasound tomography to obtain high-quality, subwavelength-resolution acoustic models of the brain using low-frequency ultrasound data. In this study is the first demonstration of this method in recovering a high-resolution 2-D reconstruction of a brain and skull ultrasound imaging phantom using experimentally acquired data.

Methods

A 2:5 scale brain phantom encased within a 3-D-printed skull-mimicking layer was created to simulate a clinical tr
