Enter, Enter/Select, or Select. Additionally, Autotrace Calc results can only be

entered from a frozen strip display (not 'live' or Cine Play).

• While Auto-Dop Trace is active, the Doppler envelope will be outlined in

green. When you freeze the strip, Automeasure numbers are displayed at the

bottom right side of the image.

• When the image is frozen, vertical BLUE line graphics delimiters will appear

on the PW strip. A small yellow arrow will appear at the top to mark the peak

systolic velocity. When you have multiple cardiac cycles displayed, a small

yellow arrow will also be displayed at the bottom to mark the peak end

diastolic.

• The placement of the delimiters is determined by how many heart cycles were

chosen in the N Cycles selection of the Auto Params menu. The heart cycle

selected for active evaluation can be changed by scrolling the Trackball to the

left or right.

• You can manually adjust the position of the delimiters by pressing the Set

button. The first press will allow for adjustment of the Left delimiter; the

second press will allowing adjustment of the Right delimiter. The calculated

Automeasure values will be adjusted accordingly.

• Auto-Dop Trace is different from conventional autotrace functions in that the

Auto-Dop Trace process is applied to the spectrum prior to any

post-processing functions (such as gain, dynamic range, edge) being applied.

• Manual adjustments to any of these post-processing functions will not affect

the Auto-Dop Trace.

NOTE: Auto-Dop Trace is intended to serve as an adjunct to the diagnostic

process in evaluating blood flow during PW Doppler examinations. When using

the Auto-Dop Trace feature, please evaluate the results to verify that you are in

agreement before committing the values to the Calc Report Package.
