Effective Dose Evaluation of Critical Organes in Digital Radiography Exames
Background and Aim: Due to the increasing number of radiographic tests, TLD dosimeters can be used to measure the effective dose of critical organs in various radiographic tests. In this research, the progression of analogue to digital radiology devices, which facilitates and accelerates the performance of radiographs, especially emergency patients, was investigated, and then the effective dose...
متن کاملComparison of Diagnostic Accuracy of Cone Beam Computed Tomography and Digital Radiography for Detection of Vertical Root Fractures with and without Gutta Percha
Objective: Diagnosis of vertical root fractures (VRFs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. Despite Cone Beam Computed Tomography (CBCT) has significantly enhanced image quality compared to digital radiography (DR) which aid the diagnosis, artifacts has remained as a problem in VRF detection . ...
متن کاملRecent Trends in Digital Industrial Radiology
New digital detectors were developed for medical applications, which have the potential to substitute the X-ray film and revolutionise the radiological technique. Flat panels and imaging plates allow a fast detection of radiographs in a shorter time and with higher dynamic than film applications. The properties of these detectors can be controlled by electronics and exposure conditions. New nam...
متن کاملReplacement of Film Radiography by Digital Techniques and Enhancement of Image Quality
New digital detectors were developed for medical applications, which have the potential to substitute the X-ray film. Digital Detector Arrays (DDA: Flat Panel Detectors, Line Detectors) and Imaging Plates (Computed Radiography, CR) allow a fast acquisition of radiographic images with higher dynamic than film. Especially DDA’s allow a radiographic inspection with considerable higher image qualit...
متن کاملComparing the Accuracy of Cone Beam Computed Tomography,Digital Intraoral Radiography and Conventional Intraoral Radiography in the Measurement of Periodontal Bone Defects
Background and Aim: Cone beam computed tomography (CBCT) produces high-quality data in periodontal diagnosis and treatment planning. The aim of this study was to compare the accuracy of CBCT with intraoral digital and conventional radiography in the measurement of periodontal bone defects. Methods and Materials: In this diagnostic research, two hundred and eighteen artificial osseous d...
