Acoustic radiation force impulse imaging (ARFI) on an IVUS circular array.
(Ultrason Imaging, 2014-04)Our long-term goal is the detection and characterization of vulnerable plaque in the coronary arteries of the heart using intravascular ultrasound (IVUS) catheters. Vulnerable plaque, characterized by a thin fibrous cap ... -
Contrast in intracardiac acoustic radiation force impulse images of radiofrequency ablation lesions.
(Ultrason Imaging, 2014-04)We have previously shown that intracardiac acoustic radiation force impulse (ARFI) imaging visualizes tissue stiffness changes caused by radiofrequency ablation (RFA). The objectives of this in vivo study were to (1) quantify ... -
In vivo guidance and assessment of liver radio-frequency ablation with acoustic radiation force elastography.
(Ultrasound Med Biol, 2008-10)The initial results from clinical trials investigating the utility of acoustic radiation force impulse (ARFI) imaging for use with radio-frequency ablation (RFA) procedures in the liver are presented. To date, data have ... -
In vivo visualization of abdominal malignancies with acoustic radiation force elastography.
(Phys Med Biol, 2008-01-07)The utility of acoustic radiation force impulse (ARFI) imaging for real-time visualization of abdominal malignancies was investigated. Nine patients presenting with suspicious masses in the liver (n = 7) or kidney (n = 2) ... -
Intracardiac acoustic radiation force impulse (ARFI) and shear wave imaging in pigs with focal infarctions.
(IEEE Trans Ultrason Ferroelectr Freq Control, 2013-08)Four pigs, three with focal infarctions in the apical intraventricular septum (IVS) and/or left ventricular free wall (LVFW), were imaged with an intracardiac echocardiography (ICE) transducer. Custom beam sequences were ... -
Intracardiac acoustic radiation force impulse imaging: a novel imaging method for intraprocedural evaluation of radiofrequency ablation lesions.
(Heart Rhythm, 2012-11)BACKGROUND: Arrhythmia recurrence after cardiac radiofrequency ablation (RFA) for atrial fibrillation has been linked to conduction through discontinuous lesion lines. Intraprocedural visualization and corrective ablation ...
