Cardiac imaging has a pivotal role in the prevention, diagnosis and treatment of ischaemic
heart disease. SPECT is most commonly used for clinical myocardial perfusion imaging …

Cardiac function and vascular function are closely related to the flow of blood within. The
flow velocities in these larger cavities easily reach 1 m/s, and generally complex …

Left ventricular (LV) blood flow is an inherently complex time-varying 3-D phenomenon,
where 2-D quantification often ignores the effect of out-of-plane motion. In this study, we …

Background Ischemic heart disease (IHD) is the leading cause of morbidity and mortality
worldwide, and imposes a serious economic load. Thus, it is crucial to perform a timely and …

Myocardial microvasculature and haemodynamics are indicative of potential microvascular
diseases for patients with symptoms of coronary heart disease in the absence of obstructive …

We have demonstrated in a patient with heart failure that HFR echoPIV can measure the,
previously unobtainable, high-velocity flow patterns in 2-dimensions. This development has …

Micro-vascular flow in the myocardium is of significant importance clinically but remains
poorly understood. Up to 25% of patients with symptoms of coronary heart diseases have no …

The heart's supply of oxygen and nutrients relies on the coronary vasculature, which
branches from millimeter-sized arteries down to micrometer-sized capillaries. To date …

Combining diverging ultrasound waves and microbubbles could improve contrast-enhanced
echocardiography (CEE), by providing enhanced temporal resolution for cardiac function …

High-frame-rate (HFR) ultrasound (US) imaging and contrast-enhanced US (CEUS) are
often implemented using multipulse transmissions, to enhance image quality. Multipulse …
