Roll, Pitch and Yaw
Roll is a rotation about the X-axis.
Pitch is a rotation about the Y-axis.
Yaw is a rotation about the Z-axis.
NOTE: Roll, pitch, and yaw positive rotation directions are established by the right hand rule (i.e. grasp
axis with right hand with thumb oriented in positive direction, fingers will then curl in direction of
positive rotation for that axis).
Absolute pitch and roll values are 0 when the ultrasound beam is parallel to the xy plane.
Absolute yaw value is 0 when the beam centerline coincides with the positive x-axis.
The positional sensor is located in the tip of all the simulator ultrasound probe types.
For the TEE probe, the omniplane rotation and flexion metrics are not captured separately but are
factored into the final position and orientation of the sensor tip.
The roll, pitch, and yaw coordinates will always fall between [-180, +180].
