Abstract

The predominant role of amplitude/phase analysis in parametric imaging of radionuclide ventriculographies has emphasised the importance of including both time and motion variables in the description of cardiac pump dysfunction. The accuracy of phase analysis for the visualisation of time patterns is hampered by the fact that a first harmonic model for the temporal behaviour of a pixels’ activity changes is assumed. We therefore have proposed a framework of alternative data extraction procedures which do include the information of the higher harmonics as well (1).
