Background, Motivation and Objective Transthoracic echocardiography is widely used to assess anatomical and physiological features of the heart. However, acoustic radiation force based methods such as ARFI, SWEI are yet to be clinically established for cardiac applications. We have previously shown the feasibility and safety of transthoracic cardiac ARFI on a research scanner but have been limited due to cardiac motion, depth of penetration and poor tracking SNR. This work aims to address these challenges on a commercial US system, validate the robustness of TTE ARFI and translate this technique into clinical practice.

目的 探讨社区空巢老人主观幸福感与社会支持、应对方式的关系。方法 以225名社区空巢老人为研究对象，采用纽芬兰纪念大学幸福度量表、领悟社会支持量表和特质应对方式问卷进行调查。结果 领悟社会支持总分及其各维度与主观幸福感呈正相关，积极应对与主观幸福感呈正相关，消极应对与主观幸福感呈负相关。积极应对和家庭内支持是主观幸福感的正向预测因子。结论 社会支持和应对方式是社区空巢老人主观幸福感重要的影响因素。
Background, Motivation and Objective In August 2014 the ESA spacecraft Rosetta encountered the comet 67P/Churyumov-Gerasimenko. Rosetta carried the lander Philae that landed on the comets nucleus onNo
Background, Motivation and Objective This paper presents an implementation of a real-time duplex synthetic aperture imaging system on a commercially available hand-held device. The implementation incl
Background, Motivation and Objective Open scanners have rapidly advanced in the past few years to offer a variety of solutions to ultrasound researchers. Each system presents specific performance in t
Background, Motivation and Objective Early diagnosis of keratoconus, a progressive disease characterized by corneal thinning and bulging, is important for avoiding corneal refractive surgery and for t
Background, Motivation and Objective During the last decade, portable ultrasound devices have been proven beneficial in a variety of situations (e.g. OB/GYN, point of care and cardiovascular applicati
Background, Motivation and Objective Ultrasonic imaging for fingerprint applications is on the rise due to better tolerance of external conditions and high spatial resolution compared to typical optic
Background, Motivation and Objective Accurate echocardiographic diagnosis of diastolic dysfunction is needed to guide heart failure treatment. Despite expected correlation between diastolic dysfunctio
Background, Motivation and Objective End stage heart failure is often treated with a left ventricular assist device (LVAD), when donor hearts are unavailable. Monitoring function of these patients is
Background, Motivation and Objective Direct and quantitative assessment of left ventricular end-diastolic stiffness (LVEDS) with ultrasound shear wave elastography (SWE) provides a potential tool for
