Computed radiography (CR) systems have been gaining adoption as digital replacements for film for diagnostic and therapy imaging. As a result, film processors are being removed from service, leaving a void for the medical physicists who use film and processors for two-dimensional mega-voltage beam dosimetry. This is the first report to evaluate the ability of a commercial CR reader and storage ...

BACKGROUND Diagnostic subtraction radiography (DSR) is a new digital radiographic image subtraction method designed to enhance detection of crestal or periapical bone density changes and to help evaluate caries progression in teeth. In this clinical study, the performance of the DSR method was evaluated for its ability to detect periodontal bone loss and was compared with that of conventional e...

The use of mammography film-screen is limited in general radiography. The purpose of this study was to compare the effectiveness of mammographic film-screen and standard film-screen systems in the detection of small bone fractures. Radiographs were taken from patients' extremities and neck areas using mammography film-screen and standard film-screen (n=57 each). Fourteen other radiographs were ...

Radiographic artifacts may mimic a clinical feature, impair image quality, or obscure abnormalities. With the development of digital radiography (DR), a new set of artifacts is introduced. Regardless of the technology, the classic technical errors that occur with film screen radiography still occur using DR. Artifacts created using computed radiography, DR, and incorrect image processing are di...

BACKGROUND Radiography plays an important role in the detection of interproximal caries. OBJECTIVES The aim of the present study was to determine diagnostic accuracy of chargecoupled devices (CCD), Photo Stimulable Phosphor (PSP) and film radiography in detecting non-cavitated caries. PATIENTS AND METHODS Seventy-two non-cavitated approximal surfaces of extracted human posterior teeth were ...

Digital imaging is becoming widely used in diagnostic radiology, and digital subtraction angiography (DSA) is now generally accepted [1-3]. Several studies have evaluated digital imaging using a computed radiography system for chest examinations [4-10] and for excretory urography [11] . This prospective study uses receiver operating curve analysis [12 , 13] to compare the diagnostic accuracy of...
