Accurate panoramic imaging

Superior clinical quality images

In order to get accurate and clear panoramic radiographs, the form of the X-ray unit focal layer must follow the actual patient anatomy. In Planmeca panoramic X-ray units, the form of the focal layer follows the scientifically defined shape of human dental arch and jaw resulting in panoramic radiographs with clearly superior clinical quality.*
 
The jaw shape and size varies between individuals according to their size, gender, race, and age. Consequently, a single panoramic focal layer form does not suit for all patients. The operator may adjust the shape of the focal layer according to the jaw shape and size characteristic to the patient in Planmeca panoramic X-ray units.**
 

Clear images with advanced imaging geometry

Planmeca panoramic X-ray unit's imaging geometry efficiently eliminates redundant shadows and ghost images caused by objects outside the image layer significantly increasing the diagnostic value of panoramic radiographs.
 
The shadow of the cervical vertebrae, which commonly disturbs the clarity of the anterior region, is automatically eliminated by adjusting the amount of radiation in the central incisor region. This computer-controlled correction ensures that there is no loss of image contrast or density.
