Summary
Matrix imaging is a promising approach in wave physics that can compensate for aberrations and scattering phenomena in heterogeneous media, but its success with ultrasonic waves has been limited due to linear transducer arrays.
This study extends ultrasound matrix imaging to a 3D geometry, allowing for a sharper estimation of the transmission matrix. Experimental proof of concept on tissue-mimicking phantoms and ex-vivo tissues demonstrates its potential, especially for transcranial applications in medical imaging.
