Only measured parameters are displayed. Location information 
is labeled with vessel name first. Measured parameters of the 
vessel are grouped under the vessel label.
Selected value by method is highlighted, however, when the 
average method is selected, the highlighted cursor is removed.
When an entire vessel measurement does not have sides (left or 
right), the side label is not displayed in that vessel study 
worksheet.
HINTSSome fields on the worksheet are view only, and others you 
can change or select. To easily see which fields you can 
change or select, move the Trackball. As the cursor moves 
over a field that you can change or select, the field is

To delete data: 
Delete Value key is used to delete value (each measured 
value). Whenever particular value is deleted, the group (set) of 
the measurement/study value is also deleted from the 
worksheet as a group (set). When PS value is deleted, ED and 
RI is also deleted if this value was measured as the set of RI 
measurement.
1. Select Worksheet from any page of the Vascular 
Calculation Touch Panel Menu.
2.  To position the cursor at the field you want to delete or 
exclude, move the Trackball.
The field is highlighted.
3. Select Delete Value.
For Example:
1.  If the user measured RI 4 times, however, latest 3 set of 
measurements were displayed in the worksheet.
1.  Then, the user deleted PS value of #3 from the worksheet.
2.  The whole set of #3 measurements is deleted from the 
worksheet and #1 set of measurements is shifted and 
displayed as below.
Result Number #2 #3 #4
PS 0.500 0.600 0.700
ED 0.100 0.200 0.300
RI 0.800 0.667 0.571
