Although the use of ultrasonic plane-wave transmissions rather than line-per-line focused
beam transmissions has been long studied in research, clinical application of this …

Non-invasive imaging deep into organs at microscopic scales remains an open quest in
biomedical imaging. Although optical microscopy is still limited to surface imaging owing to …

Starting from key ultrasound imaging features such as spatial and temporal resolution,
contrast, penetration depth, array aperture, and field-of-view (FOV) size, the reader will be …

Scanned at very high ultrasound frame rates, injectable microbubbles can be activated
sequentially as isolated punctual sources of acoustic echoes. These signals can thus be …

As in other imaging methods based on waves, the resolution of ultrasound imaging is limited
by the wavelength. However, the diffraction-limit can be overcome by super-localizing single …

Ultrasound imaging is a widely used diagnostic tool but has limitations in the imaging of
deep lesions or obese patients where the large depth to aperture size ratio (f-number) …

High-frame-rate ultrasonography based on coherent compounding of unfocused beams can
potentially transform the assessment of cardiac function. As it requires successive waves to …

Abstract Ultrafast Ultrasound Localization Microscopy uses microbubbles that are
individually localized with a resolution below 10 μm. Positions of the microbubbles are …

Ultrafast imaging using plane or diverging waves has recently enabled new ultrasound
imaging modes with improved sensitivity and very high frame rates. Some of these new …

High frame rate (HFR) imaging methods based on the transmission of defocused or plane
waves rather than focused beams are increasingly popular. However, the production of HFR …
