The ultrasound image quality is of utmost importance for a clinician to reach the correct diagnosis. Conventionally, image quality is evaluated using metrics to evaluate the contrast and resolution. These metrics requires localization of specific reg

Objectives This study aimed to investigate the potential of a novel 3-dimensional (3D) mechanical wave velocity mapping technique, based on the natural mechanical waves produced by the heart itself, to approach a noninvasive 3D stiffness mapping of t

Segmentation of cardiac structures is one of the fundamental steps to estimate volumetric indices of the heart. This step is still performed semiautomatically in clinical routine and is, thus, prone to interobserver and intraobserver variabilities. R

An aberration correction algorithm has been implemented and demonstrated in an echocardiographic clinical trial using 2D imaging. The method estimates and compensates arrival time errors between different sub- aperture processor signals in a matrix a

Inflammation is involved in initiation and progression of aortic stenosis (AS). However, the role of the complement system, a crucial component of innate immunity in AS, is unclear. We hypothesized that circulating levels of complement factor B (FB),
