Workflow Information
6. Load the images into the Dynamic Evaluation func-
tion and determine the time to the peak enhance-
ment. Alternatively, on the image segment, click
“select series” with the right mouse button and posi-
tion an ROI on the first image. This ROI will appear
on all images in the Test Bolus series. Find the image
with the peak HU value, and calculate the time “delta
t” taken to reach the peak HU value (do not forget to
add the preset start delay time). This time can then
be used as the optimal start delay time for the spiral
scan.
