To ensure proper alignment between the imaging sensor and the X-ray beam, it is
recommended to use a PID (Position Indicating Device) as shown in the following

When using the PID, the exit pattern of the X-ray device should be aligned
perpendicular to the target receptor as shown in the following figure.
Once the PID is properly aligned, instruct the patient not to move.
