- Experimental assessment of a new research tool for the estimation of two-dimensional myocardial strainStian Langeland
Cardiac Imaging Research, Dept of Cardiology, Catholic University Leuven, Leuven, Belgium
Ultrasound Med Biol 32:1509-13. 2006..Further improvements are needed for the method to be sufficiently accurate in estimating the deformation perpendicular or close to perpendicular to the ultrasound beam...
- Experimental validation of a new ultrasound method for the simultaneous assessment of radial and longitudinal myocardial deformation independent of insonation angleStian Langeland
Cardiac Imaging Research, Department of Cardiology, Catholic University Leuven, Herestraat 49, B 3000 Leuven, Belgium
Circulation 112:2157-62. 2005..To overcome this problem, we have developed a new method for the estimation of strain, independent of angle. The aim of this study was to validate this new methodology in an experimental setting using sonomicrometry...
