Evaluation of Image Magnification in Digital Panoramic Radiography
Introdouction: The aim of the present study was to investigate image magnification in digital panoramic radiography and assess the effect of anatomical sites on the magnification in both males and females. Materials and methods: In this retrospective study, digital panoramic radiographs of 48 patients with 202 implants were investigated. Implant diameter and length were measured on pan...

متن کاملImage rejects in general direct digital radiography
BACKGROUND The number of rejected images is an indicator of image quality and unnecessary imaging at a radiology department. Image reject analysis was frequent in the film era, but comparably few and small studies have been published after converting to digital radiography. One reason may be a belief that rejects have been eliminated with digitalization. PURPOSE To measure the extension of de...
متن کاملDigital rotational radiography in neuroradiology.
Different angiographic techniques (e.g., multiple oblique views, angiotomography, and magnification angiography) have been proposed to improve the diagnosis of cerebral vascular malformations and occlusive diseases. However, these methods are either time-consuming or necessitate repeated injections of contrast medium. The common goals of all these techniques are (1) to achieve a documentation o...
