Three-Dimensional Ultrasound Matrix Imaging

<strong>Raw ultrasound data associated to the paper "Three-Dimensional Ultrasound Matrix Imaging". </strong> <strong>Abstract :</strong> "Matrix imaging paves the way towards a next revolution in wave imaging.<br> Based on the response matrix recorded between a set of sensors, it enables<br> an optimized compensation of aberration phenomena and multiple scattering<br> events that usually drastically hinder the focusing process in heterogeneous<br> media. Although it gave rise to spectacular results in optical microscopy or<br> seismic imaging, the success of matrix imaging has been so far relatively lim-<br> ited with ultrasonic waves because wave control is generally only performed<br> with a linear array of transducers. In this paper, we extend ultrasound ma-<br> trix imaging to a 3D geometry. Switching from a 1D to a 2D probe enables<br> a much sharper estimation of the transmission matrix that links each trans-<br> ducer and each medium voxel. Here, we first present an experimental proof<br> of concept on a tissue-mimicking phantom through ex-vivo tissues and then,<br> show the potential of 3D matrix imaging for transcranial applications." Data corresponding to the <strong>pork chop experiment</strong>: <br> - "1_PorkChop_on_Phantom.mat" [Fig. 1, 2, 3 and Supplementary Fig. S2, S3, S4] Data corresponding to the<strong> head phantom experiment</strong>: <br> - "2_HeadPhantom_position1.mat" [Fig. 4 &amp; 5, S5, S6]<br> - "2_HeadPhantom_position2.mat" [Fig. 6] Data corresponding to the tissue mimicking phantom without aberrations: <br> - "4_Phantom_withtout_aberrations.mat" [supplementary Fig. S7] In each case : <br> - <strong>"rfr"</strong> contains the raw ultrasound data;<br> - <strong>"p"</strong> is a structure that contains all the parameters used during acquisition.
