Inadequate, incomplete or even missing records can lead to reversal of the burden of proof, resulting in a dramatically reduced chance of successful defence in litigation.
A female RANDO-phantom was exposed in five different digital panoramic radiography systems, and the dose at skin level was assessed tenfold for each measurement region by means of a highly sensitive solid-state-dosimeter. The addition of digital image collection and storage to standard and newly developed x-ray imaging techniques has allowed spectacular improvements in some diagnostic procedures. Digital radiology is a new computerized system of acquiring x-rays in a digital electronic format.
The image quality of digital radiographs was found to be significantly lower than that of film radiographs.
PACS number s: The exposure data stored on each digital detector were periodically downloaded in a spreadsheet format for analysis. Radiologists scored the images from 1 — 10 with 1 being non-diagnostic quality and 10 being superior diagnostic quality. However, the system has a limitation of lower image quality in spatial resolution and signal to noise ratio.
It is not known how many images are needed with the various CCD systems when compared with a conventional bitewing. For such cases, we show that the commonly used figures of merit based on the discrete Fourier transform can provide an inaccurate estimate of Hotelling detectability. We compared data of standing full-length lower limb radiographs and whole spine radiographs of both X-ray systems.
However, it also has disadvantages and drawbacks.
In addition, the article includes related workplace changes and medicolegal considerations in the digital radiography environment. Digital radiographs obtained using a prototype Digital Radiography System Stingray were compared with those obtained using conventional screen-film.
Ten radiologists compared the diagnostic image quality of the digital images with the corresponding film radiographs using a seven point ranking scheme.
The output of the GEANT4-based simulation is used to train neutral networks that predict the multiplicity and location of particles depositing energy inside one cluster of pixels.
Clinical performance of a prototype flat-panel digital detector for general radiography. The RR and reasons for repeated digital chest radiographs were documented over the course of 16 months while a task force of thoracic radiologists, technologist supervisors, technologists, and information technology specialists continued to examine the workflow for underlying causes.
The overall aim of this thesis was to study how digital radiography was used in general dental practices.
