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

Abstract

Radiation dose can be reduced by 75% in clinical skeletal imaging of peripheral extremities by using NIP, with no significant loss of information. For FPD images, this might be possible with a dose reduction of 50%.

Comparison of different computed radiography systems: Physical characterization and contrast detail analysis

“…5,12,21,24 The improved DQE can be exploited either to enhance the image quality, or to reduce the dose to the patients, as already assessed by other researchers. 25 The DQE of the three best systems investigated in this paper is also comparable to some of the flatpanel detectors for radiography available in the market. [26][27][28] The CD results confirm that the improved efficiency helps achieve a lower contrast threshold.…”

Storage Phosphors for Medical Imaging

“…A blind study of the images by five radiologists and five physicists lead to the conclusion that for all but two of the exposure settings NIP allowed visualization of significantly lower contrast levels. The remaining two settings also showed a trend toward better low contrast depiction with NIP. (2) A comparison of imaging performance with different doses in skeletal radiography was made for a PIP based CR system, DX-S ® and a DR system [114]. The DR system was a Siemens flat-panel detector based on a CsI:Tl + scintillator layer and an amorphous silicon sensor layer.…”

Super-resolution variable-dose imaging in digital radiography: quality and dose reduction with a fluoroscopic flat-panel detector

“…It is important to note that the CR images used in this study were obtained with standard powder-structured image plates (PIPs). It has been demonstrated by Wirth et al [21] that newer CR systems employing a needle-structured image plate [NIP] are capable of achieving considerable dose reduction and improved image quality compared to systems employing PIP's.…”
