Extraction of the Cervical Vertebrae from Panoramic X-ray image
The purpose of this study is to remove the cervical vertebrae from a dental panoramic x-ray image with a tomosynthesis method. We developed a new method to remove the cervical vertebrae from dental panoramic x-ray image. In this paper we removed artifacts caused by metalic objects in the teeth raw. To detect this area, we used a photon counting x-ray detector. The accuracy of the proposed method was validated with clinical data.
