One-Point Depth Measurement
When you are scanning in BMode using a noncardiac preset, one-point depth
measurement permits you to measure the depth of a caliper from the top of an
image by pressing the key.
Depth is calculated from the apex of the image to the center of the crosshair for
sector probes, and from the transducer-edge of the image to the center of the
crosshair for linear and curvilinear probes.
Pressing while the crosshair is active displays the current measurement in
the results box as a 2D/BMode one-point measurement.
Once you enter Analysis mode, the one-point depth measurement is unavailable.
In a trapezoidal image, one-point depths are measured:
• From the caliper along the steering angle to the skin line (depth=0) for
caliper points in the linear part of the image
• From the caliper to the skin line radially towards the origin of the sector in
the left-sector and right-sector parts of the image
