By connecting the direct digital radiography system with a PACS network, radiographs may be shared electronically like images of other digital modalities. In this scenario, productivity improvements would come mainly from shorter patient exams as a result of the immediate availability of the review ...
Background Digital radiography systems are replacing traditional film for chest radiographic monitoring in the recognition of pneumoconiosis. Methods To fu... A.,Scott,Laney,... - 《Chest》 被引量: 16发表: 2011年 Comparison of digital selenium radiography with an analog screen-film system in the...
The digital images appear to provide adequate contrast and resolution for common diagnostic tasks. In addition, the use of a scanning linear detector reduces the amount of scatter, which increases contrast relative to images made with an area detector. The system appears to provide a versatile and...
After completion of a 6-month evaluation, this system was rated favorably by the evaluators and was determined to be an excellent alternative for field-use radiography. As a result of this study, digital radiography is now being integrated in all expeditionary medical support units for future ...
Direct Digital Radiography D-DR 7 NDT Ultra-high resolution Direct Radiography Shield Scintillator Fibre Optics CMOS Chip Shock Absorber 2/2 2/2 CMOS X-ray detector for ultra-high resolution X-ray inspection and testing – meets aerospace standards!
Direct digital radiography is a radiographic method providing a rapid and relatively inexpensive means for visualizing and analyzing the internal structure of skeletal elements. Nondestructive, mobile, and compatible with multiple formats, it provides a valuable additional level of pathology data for the ...
New digital detector for projection radiography Under an applied electric field, a diagnostic x-ray signal is obtained by the direct conversion of x-ray energy to electron-hole pairs which are ... DLY Lee,LK Cheung,LS Jeromin 被引量: 263发表: 1995年 Principles of image processing in digital...
Aims: To evaluate the diagnostic accuracy of direct digital radiography as compared to a conventional radiographic film for the assessment of interproximal bone loss with intrasurgical measurements as the gold standard. Materials and Methods: A total of 100 patients, with untreated moderate-to-advanced...
sources generated by scannedelectron beam: the electron-beam computedtomography(EBCT) system[4]and the scanning beam digital x-ray (SBDX) source. A modified design of the SBDX system has been simulated for the delivery of kilovoltage x-ray beam arc therapy (KVAT) discussed in section 3.4.2...
