4D cardiac strain imaging for diagnosis of chronic heart failure

Strain imaging or elastography is a well-known technique for measuring passive and active deformation of biological tissue [1,2]. Cardiac strain imaging has been assessed as a non-invasive technique for mapping the mechanical properties of myocardial tissue and monitoring cardiac diseases, such as fibrosis and infarction [2]. The introduction of real-time 3D ultrasound imaging has boosted research in 3D strain imaging. The complex heart movements and deformations require 3D+t data for accurate assessment of strain in all directions. Sub-optimal temporal resolution of 3D datasets is still a problem. In this study…
