DESCRIPTION:Abstract: Three-dimensional ultrasound is a powerful imaging te
 chnique\, but it requires thousands of sensors and complex hardware. The d
 iscovery of compressive sensing has shown that the signal structure can be
  exploited to reduce the burden posed by traditional sensing requirements.
  In this talk\, we will give an overview of how compressive sensing can be
  used in ultrasound imaging. As an extreme example\, we have designed a si
 mple ultrasound imaging device that can perform three-dimensional imaging 
 using just a single ultrasound sensor. Our device makes a compressed measu
 rement of the spatial ultrasound field using a plastic aperture mask place
 d in front of the ultrasound sensor. The aperture mask ensures that every 
 pixel in the image is uniquely identifiable in the compressed measurement.
  Similar masks can also be used on existing ultrasound arrays to increase 
 their coverage from two-dimensional to three-dimensional. Furthermore\, we
  will discuss optimal mask designs as well as specialized algorithms that 
 can reduce the complexity and memory requirements of the state of the art 
 reconstruction methods. We demonstrate our designs with real experiments a
 nd illustrate that compressive ultrasound imaging can pave the way for che
 aper\, faster\, simpler and smaller sensing devices with possible new clin
 ical applications.\n\nCo-sponsored by: Rice University ECE Department Semi

 a powerful imaging technique\, but it&nbsp\;requires thousands of sensors 
 and complex hardware. The discovery of compressive&nbsp\;sensing has shown
  that the signal structure can be exploited to reduce the burden&nbsp\;pos

 rview of&nbsp\;how compressive sensing can be used in ultrasound imaging. 
 As an extreme&nbsp\;example\, we have designed a simple ultrasound imaging

 thermore\, we will discuss optimal mask&nbsp\;designs as well as specializ
