Mode Measurements LOGIQ 5 Basic User Manual 7-61 Direction 2300002-100 Rev. 2 Circumference and area (trace) measurement To trace the circumference of a portion of the anatomy and calculate its area: Measure• Press Measure twice; a trace caliper displays. • To position the trace caliper at the start point, move the Trackball. Set• To fix the trace start point, press Set. The trace caliper changes to an active caliper. • To trace the measurement area, move the Trackball around the anatomy. A dotted line shows the traced area. Set• To complete the measurement, press Set. The system displays the circumference and the area in the Results Window. HINTSBefore you complete the trace measurement: • To erase the line (bit by bit) back from its current point, move the Trackball or adjust the Ellipse control counterclockwise. • To erase the dotted line but not the trace caliper, press Clear once. • To clear the trace caliper and the current data measured, press Clear twice.
General Measurements and Calculations 7-62 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Doppler Mode Measurements Four basic measurements can be made in Doppler Mode. • Velocity • TAMAX, TAMIN, and TAMEAN (Manual or Auto Trace) • Two Velocities with the Slope and Time Interval between them • Time Interval NOTE: The following instructions assume that you do the following: 1. In the B-Mode part of the display, scan the anatomy you want to measure. 2. Go to the Doppler Mode part of the display. 3. Press Freeze. Ve lo c it y To measure velocity: Measure• Press Measure; an active caliper with a vertical dotted line displays. • To position the caliper at the desired measurement point, move the Trackball. Set• To complete the measurement, press Set. The system displays the velocity measurement in the Results Window.

Set• To fix the start point, press Set. • To trace the maximum values of the desired portion of the spectrum, move the Trackball. NOTE: To edit the trace line, move the Trackball. Set• To complete the measurement, press Set. The system displays the measurement values in the Results Window.

The three selections available are: Peak (TAMAX), Floor (TAMIN), and Mean (TAMEAN). To auto trace TAMAX, TAMIN, or TAMEAN: Measure• Press Measure twice; an active caliper with a vertical dotted line displays. • To position the caliper at the trace start point in the Doppler spectrum, move the Trackball. Set• To fix the start point, press Set. • To position the vertical caliper at the end point, move the Trackball. Set• To complete the measurement, press Set. The system automatically fixes both calipers and traces the maximum value between the two points. The system displays this value in the Results Window.
Mode Measurements LOGIQ 5 Basic User Manual 7-65 Direction 2300002-100 Rev. 2 Slope and time interval To measure two velocity values, the time interval (sec), and slope (m/s2): Measure• Press Measure three times; an active caliper with vertical and horizontal dotted lines displays. • To position the caliper at the start point, move the Trackball. Set• To fix the start point, press Set. The system fixes the first caliper and displays a second active caliper. • To position the second caliper at the end point, move the Trackball. Set• To complete the measurement, press Set. The system displays the two peak end point velocities, the time interval, and the slope in the Results Window.
General Measurements and Calculations 7-66 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Time interval To measure a horizontal time interval: Measure• Press Measure four times; an active caliper with a vertical dotted line displays. • To position the active caliper at the start point, move the Trackball. Set• To fix the start point, press Set. The system fixes the first caliper and displays a second active caliper. • To position the second caliper at the end point, move the Trackball. Set• To complete the measurement, press Set. The system displays the time interval between the two calipers in the Results Window.
Mode Measurements LOGIQ 5 Basic User Manual 7-67 Direction 2300002-100 Rev. 2 M-Mode Measurements Basic measurements that can be taken in the M-Mode portion of the display are: • Tissue Depth (Distance) • Time Interval • Time Interval and Slope NOTE: The following instructions assume that you do the following: 1. In the B-Mode part of the display, scan the anatomy you want to measure. 2. Go to the M-Mode part of the display. 3. Press Freeze. Tissue depth Tissue depth measurement in M-Mode functions the same as distance measurement in B-Mode. It measures the vertical distance between calipers. MeasurePress Measure once; an active caliper with a vertical and horizontal dotted line displays. To position the active caliper at the most anterior point you want to measure, move the Trackball. SetTo fix the start point, press Set. The system fixes the first caliper and displays a second active caliper. To position the second caliper at the most posterior point you want to measure, move the Trackball. SetTo complete the measurement, press Set. The system displays the vertical distance between the two points in the Results Window.
