Journal ArticleDOI
Capon beamforming in medical ultrasound imaging with focused beams
TL;DR: Phantom and in vivo images are presented to illustrate the benefits of the Capon algorithm over the conventional delay-and-sum approach and significant contrast and resolution enhancement are observed.
Book ChapterDOI
A non-disruptive technology for robust 3d tool tracking for ultrasound-guided interventions
TL;DR: An image enhancement and tool tracking technology with sub-mm accuracy for US-guided interventions is proposed, showing promise for large scale clinical impact.
Journal ArticleDOI
Microbubble cavitation imaging
Francois Guy Gerard Marie Vignon,William T. Shi,Jeffry E. Powers,E. C. Everbach,Jinjin Liu,Shunji Gao,Feng Xie,Thomas R. Porter +7 more
TL;DR: A prototype of a 2-D cavitation imager capable of producing images of the dominant cavitation state and activity level in a region of interest is presented and results for cavitation states and their changes as a function of acoustic amplitude are presented.

Ultrasonic tracking of ultrasound transducer(s) aboard an interventional tool
Francois Guy Gerard Marie Vignon,William T. Shi,Jean-Luc Robert,Ameet Kumar Jain,Luis Felipe Gutierrez +4 more
TL;DR: In this paper, an ultrasound receive beamformer (212) is configured for one-way only beamforming (112) of transmissive ultrasound using oneway delays, which is used to track, in real time, a catheter, needle or other surgical tool within an image of a region of interest.
Journal ArticleDOI
Diagnostic ultrasound induced inertial cavitation to non-invasively restore coronary and microvascular flow in acute myocardial infarction.

TL;DR: It is concluded that although short pulse duration guided therapeutic impulses from a diagnostic transducer transiently improve microvascular flow, long pulse duration therapeutic impulses produce sustained epicardial and microv vascular re-flow in acute myocardial infarction.
