6.2 How the AUTO FOCUSING(AF) mode works
In general, the panoramic images are taken along the trajectory through the averaged arch of
the patient and reconstructed later. But the patients’ arches differ in shapes individually and
correct positioning of them to ensure quality images is not easy. Moreover, to keep the correct
positioning while being imaged is more difficult. These would lead to the inferior images The
auto-focusing technology comes into play In other words, the AUTO FOCUSING, which is
incorporated into design of the PaX-Primo
i’
s intelligence model to produce optimal digital
diagnostic images, is outstanding in its performances. That is, it intelligently reconstructs a final
diagnostic image by selecting the optimal single layer in different regions of the image to
minimize image distortion in every panoramic image taken.
An artificial intelligence algorithm is employed to perform the following functions automatically.
6.2.1 Reconstructing procedures
1. Acquire the multiple layers of the images in a region.
2. Select the best single layer closest to center of the patient teeth among them.
3. Place the optimal image layer on the appropriate region of interest.
4. Repeat 1 trough 3 until the entire region of the arch is scanned and imaged.
5. After internal manipulation for the further processing, the final reconstructed image is
acquired.
