Journal ArticleDOI
A finite-element method model of soft tissue response to impulsive acoustic radiation force
TL;DR: A finite-element method (FEM) model has been developed that simulates the dynamic response of tissues to an impulsive acoustic radiation force excitation from a linear array transducer, and applications include improving image quality, and distilling material and structural information from tissue's dynamic response to ARFI excitation.
Journal ArticleDOI
Tissue-mimicking phantoms for photoacoustic and ultrasonic imaging
TL;DR: It was shown that a reasonably accurate tissue-mimicking phantom could be constructed using a gelatin base with the aforementioned additives, and it was possible to construct a phantom that mimics specific tissue acoustical and/or optical properties for the purpose of PAUS imaging studies.
Journal ArticleDOI

TL;DR: Fluorinated graphene oxide is reported for the first time as a magnetically responsive drug carrier that can serve both as a magnetic resonance imaging and photoacoustic contrast agent, under preclinical settings, and as a type of photothermal therapy.
Journal ArticleDOI
An integrated indenter-ARFI imaging system for tissue stiffness quantification.
TL;DR: An integrated indenter-ARFI (acoustic radiation force impulse) imaging system is developed that is capable of acquiring matched datasets of ARFI images and stiffness profiles from ex vivo tissue samples, which will facilitate correlation ofARFI images of tissue samples with independently-characterized material properties.
Journal ArticleDOI
In vivo assessment of myocardial stiffness with acoustic radiation force impulse imaging.
TL;DR: In vivo ARFI images showed a hemispherical, stiffer region at the ablation site whose displacement magnitude and temporal variation through the cardiac cycle were less than the surrounding untreated myocardium.
