Journal ArticleDOI
Real-Time Regularized Ultrasound Elastography
TL;DR: This paper introduces two real-time elastography techniques based on analytic minimization (AM) of regularized cost functions that produce axial strain and integer lateral displacement, while the second method produces both axial and lateral strains.
Journal ArticleDOI
Ultrasound Elastography: A Dynamic Programming Approach
Hassan Rivaz,Emad M. Boctor,Pezhman Foroughi,Richard Zellars,Gabor Fichtinger,Gregory D. Hager +5 more
TL;DR: This paper introduces a 2D strain imaging technique based on minimizing a cost function using dynamic programming (DP) that incorporates similarity of echo amplitudes and displacement continuity and generates high-quality strain images of freehand palpation elastography with up to 10% compression.
Journal ArticleDOI
Three-dimensional ultrasound-guided robotic needle placement: an experimental evaluation.
TL;DR: Clinical use of image‐guided needle placement robots has lagged behind laboratory‐demonstrated robotic capability, and Bridging this gap requires reliable and easy‐to‐use robotic systems.
Journal ArticleDOI
In vivo visualization of prostate brachytherapy seeds with photoacoustic imaging.
TL;DR: A canine study to investigate the in vivo feasibility of photoacoustic imaging for intraoperative updates to brachytherapy treatment plans finds signal-to-noise ratios (SNRs) were similar while the contrast-to thenoise ratio (CNR) was higher in SLSC compared to DAS images.

Low-cost image-guided navigation and intervention systems using cooperative sets of local sensors
Philipp J. Stolka,Emad M. Boctor +1 more
TL;DR: An augmentation device for an imaging system has a bracket structured to be attachable to an imaging component, and a projector attached to the bracket as discussed by the authors, which is arranged and configured to project an image onto a surface in conjunction with imaging by the imaging system.
