Radiographic imaging is essential in diagnosis, treatment planning and follow-up in endodontic. The new 3D imaging technologies like cone-beam computed tomography (CBCT) that are available in dental practice shows great promise in this field as it makes possible the extraction of the dental root canal shape information. CBCT reduces the radiation exposed on patient due this image quality is low contrast...
This paper presents K-edge filtering and energy weighting methods which enhance the contrast with less radiation does. Usually, energy weighting methods are used with photon-counting detector based CT for each energy bin data obtained to enhance the quality of image. However, we used these methods combine with K-edge filtering in energy-integrating detector. Using K-edge filtering, different energy...
