BACKGROUND: Automatic analyses of echocardiograms may support inexperienced users in quantifying left ventricular (LV) function. We have developed an algorithm for fully automatic measurements of mitral annular plane systolic excursion (MAPSE) and mitral annular systolic (S') and early diastolic (e') peak velocities. …

BACKGROUND: Automatic quantification of left ventricular (LV) function could enhance workflow for cardiologists and assist inexperienced clinicians who perform focused cardiac ultrasound. We have developed an algorithm for automatic measurements of the mitral annular plane systolic excursion (MAPSE) and peak velocities in …

Background: Tissue Doppler imaging is widely used to quantify global left ventricular (LV) longitudinal function. We have developed an algorithm that automatically measures the mitral annular peak velocities in systole (S'), early diastole (e') and late diastole (a'). This algorithm can be …

Introduction: With the increasing use of pocket-sized ultrasound devices by inexperienced users, automated measurements of left ventricular (LV) function will represent an advantage. LV longitudinal function is reduced in patients with systolic and diastolic dysfunction, and can be quantified by measuring the …

Simulated ultrasound data is a valuable tool for development and validation of quantitative image analysis methods in echocardiography. Unfortunately, simulation time can become prohibitive for phantoms consisting of a large number of point scatterers. The COLE algorithm by Gao et al. is …

An automatic method for measuring the fetal mean abdominal diameter (MAD) or abdominal circumference (AC) with ultrasound is proposed. From a correctly presented abdominal section suitable for MAD or AC measurement, the location of fetal abdomen is detected by image processing. Thereafter, …

Assessment of cardiac function by echocardiography is challenging for nonexperts. In a patient with dyspnea, quantification of the mitral annular excursion (MAE) and velocities is important for the diagnosis of heart failure. The displacement of the atrioventricular (AV) plane is a good …

Synthetic ultrasound data is invaluable for applications such as tuning image segmentation algorithms. Unfortunately, simulation time can become prohibitive for phantoms consisting of a large number of point-scatterers. In such cases, simplified simulation algorithms can be useful, and trade accuracy for speed. …
