In vitro verification of myocardial motion tracking from phase–contrast velocity data
M Drangova, Y Zhu, B Bowman, NJ Pelc - Magnetic resonance imaging, 1998 - Elsevier
The ability to track motion from cine phase-contrast (PC) magnetic resonance (MR) velocity
measurements was investigated using an in vitro model. A computer-controlled deformable
phantom was used for the characterization of the accuracy and precision of the forward-
backward and the compensated Fourier integration techniques. Trajectory accuracy is
limited by temporal resolution when the forward-backward technique is used. With this
technique the extent of the calculated trajectories is underestimated by an amount related to …
