Multigated cardiac studies were computer processed to produce cine mode images of
change in volume with change in time, dv/dt. In a twenty frame gated blood pool study, both …

Several techniques for the evaluation of wall motion from tomographic, radionuclide images
of the cardiac blood pool were examined. Patient images were processed, using three …

The generation of functional images from the time-activity curves of individual pixels in the
gated blood-pool study has become a routine part of most nuclear medicine computer …

In each of 50 resting subjects, two gated blood-pool image sequences were created from the
same LIST mode data set. One sequence was created using a sorting method that spans …

In addition to the ejection fractions and wall motion evaluations reported through
conventional equilibrium gated blood pool scans, left ventricular volumes and cardiac output …

METHODS Normal persons and patients with conduction ab normalities underwent ECG-
gated cardiac blood-pool imaging. After blood-pool equilibration of 20— 25mCi Tc-99m red …

Fourier phase analysis has generally been used to investigate asynchronous emptying and
filling in various heart diseases. A potential limitation of this form of analysis is curve fitting …

A combined count and geometric-based method for the calculation of left ventricular (LV)
volumes was tested using fluid filled balloons (representing the left and right ventricles (RV) …

[en] The effects of technical and geometrical factors on the left ventricular ejection fraction
(EF) obtained from gated blood pool imaging were evaluated by computer simulation …

Because of physiologic RR interval variability and arrhythmia, frame-mode acquisition of
gated images may produce erroneous left ventricular volume curves, particularly in the …
