Description
region.
Disable in cases when parts of the brain are mistakenly removed by the
ventricle-detection algorithm.
Description
Set the hematocrit values.
The ratio between the large and small vessel hematocrit values affects the
scaling in the rCBV and rCBF maps.
Description
•
Number of AIF Candidates—Set the number of automatically detected
AIF candidates.
•
Vessel's Signal—Available options include Seeds and Segmentation.
Set the vessel's signal to Segmentation to automatically mark all
segmented arteries and veins on the image. Selecting this option hides
all AIF and VOF seed marks and enables the AIF and VOF
segmentation correction tools. Segmentation is the default selected
option in MR studies.
Set the Vessel's signal to Seeds to show the AIF and VOF candidates
and to manually add AIF and VOF points on the image.
•
Split data by slice time or slice number—Use Slice Time to arrange the
slices per time stamp. Use the Slice Number option to arrange the
slices per slice number rather than slice time (for example, in cases
when the original time stamp on the slices is missing or lacking
information). The assumed time interval between slices is 1.6 s.
Your choice is retained during your entire work session.
•
Starting Time (used mainly in MR studies)—Insert the start time of the
study. The start time you insert here affects the start time displayed in
the graphic representation of the data.
•
Injection Time—Insert the contrast material injection time to override
the injection time calculated automatically by the algorithm. The line
signifying the injection time in the graphic representation of the data is
repositioned based on your manually inserted time. Use the Reset
button to revert to the original time calculated by the algorithm
automatically.
•
Perform Denoising—Enable to preprocess images for noise reduction.
This setting is turned off by default for MR studies.
