LOGIQ 7 Quick Guide
Volume
1. To make a volume calculation, do one of the
following:
•
Make one distance measurement.
•
Make two distance measurements.
•
Make three distance measurements.
NOTE: Three distances should be done in the
dual format mode (side by side images). One
measurement is usually made in the sagittal
plane and two measurements in the axial plane.
•
Make one distance and one ellipse
measurement.
•
Make one ellipse measurement.
2. Select Volume.
Time Interval Measurement
1. Press Measure twice; and active caliper with a
vertical dotted line displays.
2. To position the active caliper at the start point,
move the Trackball.
3. To fix the start point, press Set. The system
fixes the first caliper and displays a second
active caliper.
4. To position the second caliper at the end point,
move the Trackball.
5. To complete the measurement, press Set. The
system displays the time interval between the
two calipers in the measurement results
window.
Direction 2291859-100 Rev. 1
Velocity Measurement
1. Press Measure; an active caliper with a vertical
dotted line displays.
2. To position the caliper at the desired
measurement point, move the Trackball.
3. To complete the measurement, press Set. The
system displays the velocity measurement in
the measurement results window.
PI, RI, S/D Ratio, D/S Ratio or A/B Ratio
Select PI, RI, S/D Ratio, A/B Ratio or D/S Ratio
from the Doppler Touch Panel. Perform velocity
measurements.
1. The first caliper is the start point on the Doppler
waveform. This would be V
velocity for RI, systole for S/D ratio, "A" velocity
for A/B ratio or diastole for D/S ratio.
2. The second caliper is the end-point caliper to
the end point of the Doppler waveform. This
would be V
for PI, minimum velocity for RI,
d
diastole for S/D ratio, "B" velocity for A/B ratio
or systole for D/S ratio.
NOTE: For the PI calculation, if Trace Auto is not
selected, manually trace the waveform between
V
and V
.
MAX
d
NOTE: For the PI calculation, if Trace Auto is on,
the system automatically traces the waveform when
Set is pressed to fix V
.

Application specific worksheets. The worksheets
are selected from the Measurement Touch Panel.
