Currently, medical image domain translation operations show a high demand from researchers and clinicians. Amongst other capabilities, this task allows the generation of new medical images with sufficiently high image quality, making them clinically

How well the heart is functioning can be quantified through measurements of myocardial deformation via echocardiography. Clinical assessment of cardiac function is generally focused on global indices of relative shortening; however, segmental strain

Due to privacy issues and limited amount of publicly available labeled datasets in the domain of medical imaging, we propose an image generation pipeline to synthesize 3D echocardiographic images with corresponding ground truth labels, to alleviate t

Purpose: In recent years, there has been increased clinical interest in the right ventricle (RV) of the heart. RV dysfunction is an important prognostic marker for several cardiac diseases. Accurate modeling of the RV shape is important for estimatin

High frame rate three-dimensional echocardiography (3DE) improves the assessment of the cardiac dynamics by providing a realistic view of the cardiac structures. However, since the field of view in 3D is large and the speed of sound in tissue is limi

The temporal resolution of echocardiographic sequences affects the interpretation of cardiac motion as well as the viewing experience. Temporal resolution, however, is limited by the propagation velocity of sound in tissue. Altering the acquisition s

In this paper, we propose a multiscale nonlocal means-based despeckling method for medical ultrasound. The multiscale approach leads to large computational savings and improves despeckling results over single-scale iterative approaches. We present tw

A real-time scan assistant (SA) for use with echocardiography is presented. The motivation is to aid nonexpert users in capturing apical 4-chamber views (A4CH) during echocardiography. The algorithm is based on a parametric multi-chamber model of the

This paper propose a dynamic model of an electropneumatic clutch actuator system for heavy duty trucks. The focus is set on modeling of the clutch load characteristic which should be parameter affine, and the main purpose of the modeling task in this

Speckle noise is inherent in ultrasound imaging where it causes reduced contrast resolution and degrades the detectability of small structures. In this paper we propose a real-time multiscale despeckling filter based on the recently proposed Nonlocal
