}ah  DukeUltrasound is an ultrasound dataset collected at Duke University with a 
Verasonics c52v probe. It contains delay-and-sum (DAS) beamformed data 
as well as data post-processed with Siemens Dynamic TCE for speckle 
reduction, contrast enhancement and improvement in conspicuity of 
anatomical structures. These data were collected with support from the
National Institute of Biomedical Imaging and Bioengineering under Grant 
R01-EB026574 and National Institutes of Health under Grant 5T32GM007171-44.
