Wall-less Flow Phantoms with 3D printed Soluble Filament for Ultrasonic Experiments

Current Directions in Biomedical Engineering, 2023
Tissue-mimicking materials (TMMs) typically used for ultrasound phantoms include gelatin, agarose and polyvinyl alcohol (PVA). These materials have shown sufficient similarity in ultrasound parameters compared to human tissue. Despite their extensive use

The impact of vaporized nanoemulsions on ultrasound-mediated ablation [PDF]

, 2013
BACKGROUND: The clinical feasibility of using high-intensity focused ultrasound (HIFU) for ablation of solid tumors is limited by the high acoustic pressures and long treatment times required.

Doppler twinkling artifact observations: an open-access database of raw ultrasonic signals [PDF]

Digital Diagnostics, 2021
BACKGROUND: Doppler twinkling artifact is a rapid change of colors seen in CFI-mode in the presence of kidney stones and calculi. Therefore, numerous researchers use the twinkling artifact as a diagnostic sign.

Active phantoms: a paradigm for ultrasound calibration using phantom feedback [PDF]

Journal of Medical Imaging, 2017
In ultrasound (US)-guided medical procedures, accurate tracking of interventional tools is crucial to patient safety and clinical outcome. This requires a calibration procedure to recover the relationship between the US image and the tracking coordinate system.
