Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...

While recent advances in radiologic imaging have focused on CT and MRI technology, progress in digital radiographic techniques has also had significant impact on our ability to evaluate cardiothoracic disease. A number of publications have established the improved image quality of digital imaging systems over conventional film techniques [1]. While image quality has clearly improved with digita...

Several different image processing methods are described and discussed. Their applicability to the processing of images from digital radiography equipment is compared. The overall conclusion is that advanced image enhancement methods are beneficial and can improve detectability of flaws in digital radiography images, but that these enhancement methods have to be used carefully, especially in ca...

ntroduction: the aim of this study was to compare the accuracy of cone-beam computed tomography (cbct), digital radiography and tooth sectioning in evaluating root canal morphology of mandibular incisors in an in vitro setting. methods and materials: a total of 76 samples were imaged using cbct, and digital radiography in straight and angled views. the samples were then sectioned at different d...

background radiography is as a part of periodontal examination. early detection of periodontal disease is important in the prevention of tooth loss and patient’s general health. objectives the objective of this study was to compare diagnostic accuracy of cone-beam computed tomography (cbct) with digital direct intraoral radiography, in assessment of periodontal osseous lesions. materials and me...

conclusion dt-sfp can improve the detection of relatively early bone abnormalities in acetabular and proximal femur compared with conventional radiography. dt-sfp can also observe the abnormal impact between acetabular and proximal femur. patients and methods ninety-four consecutive patients with discomfort around the hip joint underwent dt-sfp and conventional radiography. the imaging features...

PURPOSE This laboratory study compared visual-tactile examination with conventional radiographs, digital radiographs, and laser fluorescence in the detection of occlusal occult caries on extracted premolar teeth. METHODS Extracted premolars without obvious caries or restorations were collected from school dental clinics. Occlusal surfaces of 320 extracted premolars were examined visually with...

Introduction: The use of digital radiography systems has become more common all around the world. Ideal situation in radiography is to maximize the image quality while minimizing the patient dose. The purpose of this study was to compare image quality and radiation dose in different digital radiography systems. Materials and Methods: Images of Pehamed FLUORAD ...
