Target Cut Plane vs. Captured Cut Plane Comparison
NOTE: Captured cut plane position refers to the position of the probe when the “Stop Metrics” button is
pressed.
Term Definition
Target Cut Plane Probe Position The absolute X, Y, Z coordinates of the target cut plane ultrasound
probe position relative to the coordinate system origin.
Captured Cut Plane Probe
Position The absolute X, Y, Z coordinates of the captured cut plane probe
position relative to the coordinate system origin.
Position Difference The X,Y,Z positional differences between the ultrasound probe in
the target cut plane position and captured cut plane position.
Total Positional Difference The total distance between the ultrasound probe target cut plane
and captured cut plane positions is calculated as sqrt((X2-
X1)
2
+(Y2-Y1)
2
+(Z2-Z1)
2
).
Target Cut Plane Probe
Orientation The absolute roll, pitch, yaw orientations of the target cut plane
ultrasound probe position relative to the coordinate system
origin.
Captured Cut Plane Probe
Orientation The absolute roll, pitch, yaw orientations of the captured cut
plane ultrasound probe position relative to the coordinate system
origin.
Orientation Difference The roll, pitch, yaw orientation differences between the ultra-
sound probe in the target cut plane position and captured cut
plane position.
Total Orientation Difference The rotation required to align the captured cut plane with the tar-
get cut plane. It is calculated as the quaternion angle combining
the contributions of roll, pitch, and yaw into the single and most
direct rotation which takes place around a newly created vector
in space.
