Understanding the ultrasound pressure-driven dynamics of microbubbles confined in viscoelastic materials is relevant for multiple biomedical applications, ranging from contrast-enh…
Transverse flow under oscillating stimulation in helical square ducts with cochlea-like geometrical curvature and torsion
Noëlle Harte, Dominik Obrist, Marco Caversaccio +2
The cochlea is our fluid-filled organ of hearing with a unique spiral shape. The physiological role of this shape remains unclear. Previous research has paid only little attention…
Super-Resolved Microbubble Localization in Single-Channel Ultrasound RF Signals Using Deep Learning
Nathan Blanken, Jelmer M. Wolterink, Hervé Delingette +3
Recently, super-resolution ultrasound imaging with ultrasound localization microscopy (ULM) has received much attention. However, ULM relies on low concentrations of microbubbles i…
US Velocimetry in Participants with Aortoiliac Occlusive Disease
Stefan Engelhard, Majorie van Helvert, Jason Voorneveld +5
The accurate quantification of blood flow in aortoiliac arteries is challenging but clinically relevant because local flow patterns can influence atherosclerotic disease. To invest…
Time-resolved velocity and pressure field quantification in a flow-focusing device for ultrafast microbubble production
Sarah Cleve, Christian Diddens, Tim Segers +2
Flow-focusing devices have gained great interest in the past decade, due to their capability to produce monodisperse microbubbles for diagnostic and therapeutic medical ultrasound…
