Because it drives the compromise between resolution and penetration, the diffraction limit
has long represented an unreachable summit to conquer in ultrasound imaging. Within a …

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 …

Ultrafast ultrasonic imaging is a rapidly developing field based on the unfocused
transmission of plane or diverging ultrasound waves. This recent approach to ultrasound …

The emergence of ultrafast frame rates in ultrasonic imaging has been recently made
possible by the development of new imaging modalities such as transient elastography …

Supersonic shear imaging (SSI) is a new ultrasound-based technique for real-time
visualization of soft tissue viscoelastic properties. Using ultrasonic focused beams, it is …

Very high frame rate ultrasound imaging has recently allowed for the extension of the
applications of echography to new fields of study such as the functional imaging of the brain …

Doppler-based flow analysis methods require acquisition of ultrasound data at high spatio-
temporal sampling rates. These rates represent a major technical challenge for ultrasound …

This paper presents an initial clinical evaluation of in vivo elastography for breast lesion
imaging using the concept of supersonic shear imaging. This technique is based on the …

Hemodynamic changes in the brain are often used as surrogates of neuronal activity to infer
the loci of brain activity. A major limitation of conventional Doppler ultrasound for the …
