SUMMARY:Ultrafast ultrasound imaging: a paradigm shift for ultrasonography
  and its application to blood pressure measurments. - Jerome Baranger\, CN

DESCRIPTION:Ultrafast ultrasound imaging represents a major breakthrough c
 ompared to traditional ultrasound techniques. With the development of full
 y digital scanners that use plane or divergent ultrasound waves\, it is no
 w possible to capture images at up to 10\,000 frames per second\, far exce
 eding the typical 50 frames per second of conventional systems. This leap 
 in speed allows researchers to observe rapid and fleeting physiological pr
 ocesses in the human body that were previously invisible. The seminar will
  focus on one such process: the behavior of major arteries. By examining s
 omething as routine as taking blood pressure\, we uncover a world of intri
 cate and revealing physical phenomena. A central question will be the orig
 in of Korotkoff sounds\, those distinctive noises heard through a stethosc
 ope during blood pressure measurement. Though discovered over a century ag
 o\, the exact mechanisms behind these sounds have remained unclear\, and u
 ltrafast ultrasound offers new tools to finally unravel this long-standing
  scientific mystery.
