Conference IEEE International Ultrasonics Symposium Ius · October 31, 2017 Cardiac function has traditionally been studied using pressure-volume (PV) loop analysis. PV loops can be used to derive functional indices such as end-systolic pressure volume relationship (ESPVR) - a measure of myocardial contractility, end-diastolic pre ... Full text Cite

A novel drift compensation algorithm for improved beat-to-beat repeatability of myocardial strain imaging: Preliminary in vivo results

Conference IEEE International Ultrasonics Symposium Ius · October 31, 2017 Myocardial strain imaging has been shown to add significant prognostic and diagnostic value to echocardiography. While the reliability of ultrasound-based strain measurement techniques has improved considerably in terms of regional consistency and inter-re ... Full text Cite

Notice of Removal: A novel strain-based drift compensation algorithm for improved beat-to-beat repeatability of myocardial strain imaging: Preliminary in vivo results

Conference IEEE International Ultrasonics Symposium Ius · October 31, 2017 Strain imaging is gaining traction as a means to assess cardiac function by tracking the cyclic deformation of the myocardium. Compared to traditional measures such as ejection fraction, global myocardial strain has been shown to be an earlier and more sen ... Full text Cite

Notice of Removal: High speed clinical Strain measurements

Conference IEEE International Ultrasonics Symposium Ius · October 31, 2017 High speed ultrasound imaging is a new imaging method particularly applicable to cardiology. At Duke we have developed a real time high speed imaging system capable of producing up to 2500 images per second while maintaining the live imaging feature so ess ... Full text Cite

Notice of Removal: Clinical feasibility of a noninvasive method to interrogate myocardial function via strain and acoustic radiation force-derived stiffness

Conference IEEE International Ultrasonics Symposium Ius · October 31, 2017 Myocardial elastance, derived from pressure-volume (PV) loops in the left ventricle (LV), can be used to assess LV function and myocardial performance. This method requires an invasive intracardiac pressure-volume catheter to be inserted in the LV, limitin ... Full text Cite

Feature tracking algorithm for circumferential strain using high frame rate echocardiography

Conference Computing in Cardiology · March 1, 2016 This study aims to describe a feature tracking algorithm tailored to estimate circumferential strain on high frame rate ultrasound (HFR-US) images. The algorithm used the Hungarian assignment algorithm for tracking a basic feature descriptor. A second orde ... Cite

In vivo transthoracic measurements of acoustic radiation force induced displacements in the heart over the cardiac cycle

Conference 2015 IEEE International Ultrasonics Symposium Ius 2015 · November 13, 2015 Myocardial elasticity is an important indicator of cardiac function and is affected in many disorders associated with heart failure. Ultrasound based interrogation of cardiac stiffness has been extensively studied in ex-vivo, open chest and intracardiac im ... Full text Cite

Blood flow visualization with real time high speed ultrasound

Conference IEEE International Ultrasonics Symposium Ius · October 20, 2014 A new method of acquiring and displaying high speed ultrasound images has been developed. To extract flow information from the low intensity reflections of moving blood in these high frame rate images, difference imaging was found to be a particularly appl ... Full text Cite

Active contour based on the elliptical Fourier series, applied to matrix-array ultrasound of the heart

Conference Proceedings of SPIE the International Society for Optical Engineering · December 1, 1997 We describe an active contour based on the elliptical Fourier series, and its application to matrix-array ultrasound. Matrix-array ultrasound is a new medical imaging modality that scans a 3D-volume electronically without physically moving the transducer, ... Full text Cite
