a meter [m]. If the unit of each measurement value of this
formula is defined as centimeter [cm], you must define the
formula as follows:

Mode Measurements LOGIQ 5 Basic User Manual 7-57 Direction 2300002-100 Rev. 2 Mode Measurements B-Mode Measurements Two basic measurements can be made in B-Mode. • Distance • Circumference and Area (Ellipse or Trace Method) NOTE: The following instructions assume that you first scan the patient and then press Freeze. Distance measurement To make a distance measurement: Measure• Press Measure once; an active caliper 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 active caliper at the end point, move the Trackball. A dotted line connects the measurement points. Set• To complete the measurement, press Set. The system displays the distance value in the Results Window.
General Measurements and Calculations 7-58 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Distance measurement (continued) The following hints can help you to perform distance measurements: HINTS• Before you complete a measurement: • To toggle between active calipers, press Measure. • To erase the second caliper and the current data measured and start the measurement again, press Clear once. • To rotate through and activate previously fixed calipers, adjust Cursor Select. • After you complete the measurement, to erase all data that has been measured to this point, but not data entered onto worksheets, press Clear.
Mode Measurements LOGIQ 5 Basic User Manual 7-59 Direction 2300002-100 Rev. 2 Circumference and area (ellipse) measurement You can use an ellipse to measure circumference and area. To measure with an ellipse: Measure• Press Measure once; an active caliper displays. • To position the active caliper, 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, move the Trackball.
General Measurements and Calculations 7-60 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Circumference and area (ellipse) measurement (continued) • Adjust the Ellipse control; an ellipse with an initial circle shape displays. • To position the ellipse and to size the measured axes (move the calipers), move the Trackball. • To increase the size, adjust the Ellipse control in a clockwise direction. To decrease the size, adjust the Ellipse control in a counterclockwise direction. Measure• To toggle between active calipers, press Measure. Set• To complete the measurement, press Set. The system displays the circumference and area in the Results Window. HINTSBefore you complete the ellipse measurement: • To erase the ellipse and the current data measured, press Clear once. The original caliper is displayed to restart the measurement. • To exit the measurement function without completing the measurement, press Clear a second time.
