Digital radiographic technique and its clinical application

Accurate diagnosis is essential to ensure the most effective treatment for patients in dentistry. Among all diagnostic tools the X-ray examination is the method most often for diagnosing hard tissue changes in dental clinics. 

At the Division of Image and Functional Odontology our research focuses on a variety of topics in the field of oral maxillofacial radiology from physical properties of digital radiographic systems, image processing methods to assessment of image quality and diagnostic performance of different image modalities.  Development in digital technique makes it possible to reduce radiation dose to the patients while maintaining optimal image quality. This is mainly due to more sensitive digital receptor together with well functioned image enhancement algorithms. The general aim of our research is to verify whether the improved radiographic technique affect radiographic diagnosis under clinical situations.
