• Start the preview series reconstruction at a time
point over or just before the T-wave (end ventricular
systole). The settings should be sufficient to cover
the cardiac cycle up to the R-wave (end ventricular
diastole).
• Determine ED and ES on the Test Series ES: end sys-
tolic, maximum contraction of the myocardium,
smallest left ventricular lumen. ED: end diastolic,
minimum contraction. Use graphics tools (zoom &
pan) to enlarge the image, switch between images
to select ES and ED. It is also helpful to use the dis-
tance tool to find the images with maximum and
minimum myocardial contraction. If ED or ES cannot
be clearly determined because there are two adja-
cent images with the same contraction, use the
phase in between.
• Reconstruction of two full axial image series with the
time-points for ES and ED determined from the test
series.
•Press Preview Series button.
• A preview series will be reconstructed.
