Probe Angular Movement
(degrees) The sum of angular orientation movements by the ultrasound
probe during each time step since time = 0. The orientation angu-
lar movement during a time step between start position 1 and
end position 2 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.
Roll Difference Target (degrees) The relative roll orientation difference between the ultrasound
probe and the target cut plane ultrasound probe position.
Pitch Difference Target
(degrees) The relative pitch orientation difference between the ultrasound
probe and the target cut plane ultrasound probe position.
Yaw Difference Target (degrees) The relative yaw orientation difference between the ultrasound
probe and the target cut plane ultrasound probe position.
Total Orientation Difference
Target (degrees) The total angular orientation difference between the current
ultrasound probe position 1 and the target cut plane ultrasound
probe position 2. It is calculated as the quaternion angle combin-
ing the contributions of roll, pitch, and yaw into the single and
most direct rotation between the points which takes place
around a newly created vector in space.
Beam Depth of Field (cm) The beam depth of field setting
Beam Angle (degrees) The beam angle setting
