Cardiac imaging (ultrasound)

Echocardiography is one of the most important diagnostic tools in cardiology. Recent advances in ultrasound hardware and software have made 3-dimensional echocardiography, high frame rate imaging and speckle tracking echocardiography possible. These techniques are used for estimation of left ventricular function according to the classically defined volumes and ejection fractions but also for deformation and rotation imaging. Finally, shear wave imaging is a new research tool to investigate the stiffness of the heart. In this technique, either physiological or externally-induced mechanical waves are tracked with high frame rate imaging to assess their velocity, which is then converted to stiffness. This research is done within the Medical Delta framework in collaboration with Acoustical Wavefield Imaging of Delft University of Technology.
