Dosimetry of Occupational Radiation around Panoramic X-ray Apparatus
Background: Panoramic imaging is one of the most common imaging methods in dentistry. Regarding the side-effects of ionizing radiation, it is necessary to survey different aspects and details of panoramic imaging. In this study, we compared the absorbed x-ray dose around two panoramic x-ray units: PM 2002 CC Proline (Planmeca, Helsinki, Finland) and Cranex Tome (Soredex, Helsinki, Finland).<br ...
متن کاملA Problem of Automatic Segmentation of Digital Dental Panoramic X-Ray Images for Forensic Human Identification
Dental radiographic images are one of the most popular biometrics used in the process of forensic human identification. This led to the creation of the Automatic Dental Identification System with the goal of decreasing the time it takes to perform a single search in a large database of dental records. A fully automated system identifying people based on dental X-ray images requires a prior segm...
متن کاملSegmentation and Feature Extraction of Panoramic Dental X-Ray Images
Automating the process of analysis of Panoramic X-Ray images is important to help dentist procedures and diagnosis. Tooth segmentation from the radiographic images and feature extraction are essential steps. The authors propose a segmentation approach based on mathematical morphology, quadtree decomposition for mask generation, thresholding, and snake models. The feature extraction stage is ste...

متن کاملAppearance of Anatomical Structures of Mandible on Panoramic Radiographs (Panorex-X-Ray) in Patients who Referred to Dental School of Shahid Beheshti University
Purpose: Currently panoramic radiography is used for diagnostic dental, and bone lesions, but anatomical structures also can see, for example incisive canal. At present time incisive canal position is investigated in Iranian population. Materials and Methods: Panoramic radiographs were taken by Planmeca machine from 412 patients using standard exposure. The position of patient was in compliance...
