Computed ultrasound tomography in echo mode for imaging speed of sound using pulse-echo sonography: proof of principle.
TL;DR: A novel method by which speed- of-sound imaging is possible using classic pulse-echo equipment, facilitating new clinical applications and the combination with state-of-the art diagnostic ultrasound is presented.

Study of clutter origin in in-vivo epi-optoacoustic imaging of human forearms
TL;DR: In this paper, a linear array probe for scanning the human forearm was used to identify the main source of clutter in clinical epi-opto-acoustic imaging, which is caused by strong optical absorbers located at the irradiation spot.

TL;DR: In this article, a displacement-compensated averaging (DCA) technique for clutter reduction based on the clutter decorrelation that occurs when palpating the tissue was proposed, which was implemented in a combined clinical OA and US imaging system.

TL;DR: The experience with freehand scanning of human volunteers reveals that real-time feedback on the clutter-reduction outcome is a key factor for achieving superior contrast and imaging depth.

Computed Ultrasound Tomography in Echo mode (CUTE) of speed of sound for diagnosis and for aberration correction in pulse-echo sonography
TL;DR: In comparison to previous reflection-mode based methods, CUTE works also in a situation with only diffuse echoes, and its direct reconstruction algorithm enables real-time application, which makes it suitable as an addition to conventional clinical ultrasound where it has the potential to benefit diagnosis in a multimodal approach.
