Aim To compare digital images of conventional radiographs with the original radiographs for perceived clarity of periapical lesions and the quality of root canal treatment. Materials and Methods One hundred and four intraoral periapical radiographs of patients with endodontically treated teeth were randomly selected. The radiographs were digitized using an MD300 USB X-ray Reader. The digital ...

Developments in digital radiography (DR) may have held the high ground of x-ray imaging on the RSNA exhibit floor this year, but technical improvements in surgical C-arms, conventional radiography/fluoroscopy, and angiography equipment were exciting, even extraordinary in some cases. Advanced software applications in x-ray have flourished as well, particularly in 3D imaging and digital displays...

Background: Radiotherapy Treatment Planning requires different dosimetric quantities as input in order to calculate a desired dose distribution. This study has been focused to evaluate the depth dose characteristics of superficial X-rays being used for radiotherapy treatment. Materials and Methods: Computerized 3-D water phantom of multi-data system was used. The measurements were made...

The purpose of this study was to optimize X-ray conditions for full spine X-ray examinations in slot-scan digital radiography (SSDR). Follow-up of spinal deformities, such as scoliosis, typically involves many radiographs of the patient throughout childhood and adolescence. The Radiation doses for the full spine X-ray examination should be minimized. Recently, SSDR has been introduced for full ...

Templating x-rays of total hip and knee replacements pre-operatively are important to plan surgery. This is usually done using acetate templates of the prosthesis on hard copies of the x-ray. With the change in practice, to use digital x-rays on computer screens instead of hard copies, it is important to assess if acetate templates can be used for digital x-rays on the computer screen. This is ...

The global digital elevation model (DEM) produced by the TanDEM-X (TerraSAR-X add-on for measurements) mission is an interferometric with unprecedented quality, accuracy, and coverage. It represents unedited surface as artifacts inherent to synthetic aperture radar acquisition processing technique are still present. most prominent in DEM water bodies appearing a rough due low coherence. Additio...
