The effectiveness of a positioning doll for radiography training (XPD) and acquiring the techniques of radiography was evaluated through performing radiography practice for the students in our school of radiological technologists and a questionnaire for radiological technologists. We made a ranking test composed of a five-grade evaluation system of the 39 students for the techniques of radiogra...

PURPOSE The purpose of this review is to evaluate the possibility of panoramic radiography as a national oral examination tool. MATERIALS AND METHODS This report was carried out by review of the literatures. RESULTS Panoramic radiography has sufficient diagnostic accuracy in dental caries, periodontal diseases, and other lesions. Also, the effective dose of panoramic radiography is lower th...

Energetic protons from an accelerator may be used to produce radiographs showing unusually high contrast but relatively poor spatial resolution.

Dentists play an essential part in complex forensic scenarios, such as the identification of putrefied and charred bodies as well as skeletal remains, in which fingerprint analysis becomes unfeasible [1]. Specifically in charred bodies, the anterior teeth are often found fragile or destroyed after exposed to a high temperature. However, the posterior teeth are mostly preserved by the adjacent s...

background & aims: thuracolumbar unstable fractures (t, l.u.f) are common after spine truma. posterior pedicular fixation is a technique that is use for fixation of these fractures. this study evaluates the accuracy of pedicular screw placement in t, luf with the assistance of plain radiography in operation rooms. materials & methods: this study is a case-control and analytical study. 35 patien...

Background: Chest radiography is one of the most usual diagnostic tools for respiratory distress. Objective: The purpose of this study is to assess the specificity, sensitivity and clinical value of chest radiography of neonates with respiratory distress.Patients and Methods: A descriptive- analytical study was conducted on 102 neonates that were in neonatal intensive care unit of Imam Reza and...

After describing the principles of the "in pool" and "dry" installations, techniques used in neutron radiography are reviewed. Use of converter foils with silver halide films for the direct and transfer methods is described. Advantages of the use of nitrocellulose film for radiographying radioactive objacts are discussed. Dynamic imaging is shortly reviewed. Standardization in the field of neut...
