Bildqualität und Dosis in der Digitalen Projektionsradiographie

Abstract

Flat plate radiography systems demonstrate the highest potential for high image quality when reducing the exposure dose. Depending on the system generation, the storage phosphor systems also show an improved image quality, but the possibility of a dose reduction is limited in comparison with the flat plate detector system.

Initial Clinical Results with a New Needle Screen Storage Phosphor System in Chest Radiograms

“…These results were confirmed by another trial in which fractured wrist specimens were employed [13]. Busch et al compared different storage phosphor systems to a flat-panel detector system at different dose levels in radiograms of a low contrast technical phantom, hand-phantom, abdomen-phantom and chest-phantom [14]. In this study the highest potential for dose reduction was seen in flat panel detectors followed by the SP systems.…”

Imaging Performance with Different Doses in Skeletal Radiography: Comparison of a Needle-structured and a Conventional Storage Phosphor System with a Flat-Panel Detector

“…In previous studies, FPD systems were compared with screen-film combinations (3)(4)(5)(6)(9)(10)(11)(12)(19)(20)(21)(22)(23)(24), storage phosphor systems (7,11,19,20,(24)(25)(26)(27)(28)(29), and both (11,19,20,24). In all of those studies, images obtained with FPD systems were rated superior to images obtained with screen-film combinations and storage phosphor systems in terms of image quality and noise, as well as high-and lowcontrast detection.…”

Radiation Protection in Diagnostic Radiology

“…Exposure may be reduced by optimizing the procedure and by avoiding unnecessary imaging, particularly repeats, or inexpertly performed tests. Particularly in exclusion diagnoses by imaging procedures, ultrasound and magnetic resonance tomography should be the procedures of first choice, in so far as this is possible, as these supply information for further diagnostic and therapeutic measures without using ionizing radiation (25).…”
