14 Chapter 4 Imaging Software Overview
IPS Aiming Ring Interface and RVG Sensor Centering
The IPS aiming ring interface enables you to correctly position the X-ray generator to the RVG sensor.
The IPS interface enables you to manage the X-ray centering and the proper paralleling technique
achievement.
Sensor Display
• Sensor is not centered.
• Centering indicators are
red.
Result
• Sensor active surface not fully
exposed to X-ray.
• Image will have a cone cut.
• Parallel technique not achieved.
• Image distortion.
Sensor Display
• Sensor is centered.
• Centering indicators are
red.
Result
• Sensor active surface is fully exposed
to X-ray;
• Image will have no cone cut.
• Parallel technique not achieved.
• Minimized risk of magnification and
distortion.
Sensor Display
• Sensor is centered.
• Centering indicators are
green.
Result
• Sensor active surface is fully exposed
to X-ray;
• Image will have no cone cut.
• Parallel technique achieved*.
• Minimized risk of magnification and
distortion.
Important: *The paralleling technique is achieved when the digital sensor
plane is placed parallel to the real axis of the tooth in the patient’s mouth.
This correct positioning is under the operator’s responsibility.
