Planmeca ARA™ Artefact Removal Algorithm
Metal restorations and root fillings in the patient’s mouth can cause shadows and streaks in CBCT images. The intelligent Planmeca ARA™ system removes these artefacts efficiently from Planmeca ProMax® 3D images.
- Removes streaks and artifacts efficiently
- Based on a heuristic model
- The result of extensive scientific research and a vast amount of clinical patient data
- Artefact removal is enabled from Planmeca Romexis® 3D image capturing dialog according to the patient case (choose from low, medium or high). It can be performed multiple times at different levels using original exposure data.
To avoid these artefacts from occurring, we suggest the following:
Make sure to use the Planmeca ARA™ artefact removal algorithms when imaging patients with a noticeable amount of previous dental work. The Planmeca ARA algorithm can be activated before image acquisition, but artefact removal can also be done manually after exposure. The most important aspect of metal artefact removal is to remove only the unwanted artefacts – without weakening the diagnostic value of the scan by altering the image too much.
The Planmeca ProMax® 3D head support was designed to provide the best balance between head stabilisation and patient comfort. It is also recommended that patients sit in a chair with locked wheels, which has been provided with the unit. Patients can also be advised to keep their eyes closed during the scan.
The longer the scan time, the more time the patient has to move during the scan. Therefore it might be favorable to use the Planmeca Ultra Low Dose™ imaging protocol that allows a faster scan time in addition to a lower effective patient dose.
