The purpose of this study was to examine the correlation between the basic imaging properties of two digital radiographic X-ray systems with a direct conversion flat-panel detector and their image qualities, which were evaluated by the observer in hard copy and soft copy studies. The subjective image quality was evaluated and compared in terms of the low-contrast detectability and image sharpne...

BACKGROUND A thorough quality analysis of radiologic performance is cumbersome. Instead, the prevalence of missed cervical hip fractures might be used as a quality indicator. PURPOSE To validate a computer-based quality study of cervical hip fracture radiography. MATERIAL AND METHODS True and false negative and positive hip trauma radiography during 6 years was assessed manually. Patients w...

Although some things have not changed much since Merrill Sosman's time, many ethical and economic aspects of medical practice are now being scrutinized much more closely than in the past. Among the questions being asked are the following: Are physicians overutilizing technology? How much and by what criteria are physicians being paid (or overpaid)? Is the best possible quality of care being pro...

The accessibility of digital radiography (DR) provides a means for equine practitioners to obtain high-quality diagnostic images of the back in the standing horse. In the past, the use of conventional films has discouraged many equine veterinarians from performing comprehensive radiographic examinations of the back, because their size and thickness restricted the quality of the image. DR system...

The degree of angulation of the X-ray beam relative to the radiographic film is a limiting factor in obtaining diagnostic quality flexor view radiographs. The use of an angled cassette tunnel yields an improvement in the quality of the radiographs obtained.

Digital radiographic imaging systems, such as those using photostimulable storage phosphor, amorphous selenium, amorphous silicon, CCD, and MOSFET technology, can produce adequate image quality over a much broader range of exposure levels than that of screen/film imaging systems. In screen/film imaging, the final image brightness and contrast are indicative of over- and underexposure. In digita...

Electrical stimulation is a common adjunct used to promote bone healing; its efficacy, however, remains uncertain. We conducted a meta-analysis of randomized sham-controlled trials to establish the efficacy of electrical stimulation for bone healing. We identified all trials randomizing patients to electrical or sham stimulation for bone healing. Outcomes were pain relief, functional improvemen...

background:  adolescent idiopathic scoliosis (ais) may lead to physical and mental problems. it also can adversely affect patient satisfaction and the quality of life. in this study, we assessed the outcomes and satisfaction rate after surgical treatment of ais using scoliosis research society-30 questionnaire (srs-30).   methods:  we enrolled 135 patients with ais undergoing corrective surgery...

Quality assurance (QA) of the image quality for image-guided localization systems is crucial to ensure accurate visualization and localization of regions of interest within the patient. In this study, the temporal stability of selected image parameters was assessed and evaluated for kV CBCT mode, planar radiographic kV, and MV modes. The motivation of the study was to better characterize the te...
