Investigation of Scintillation Screens for X-Ray Imaging
Terbium-doped gadolinium oxysulfide (Gd2O2S:Tb) phosphor screen is the most popular X-ray converter in diagnostic radiology. We have investigated the fundamental imaging performance of Gd2O2S:Tb screens in terms of X-ray sensitivity and MTF (modulation-transfer function). The measurements were perfo...

| Zusammenfassung: | Terbium-doped gadolinium oxysulfide (Gd2O2S:Tb) phosphor screen is the most popular
X-ray converter in diagnostic radiology. We have investigated the fundamental imaging performance
of Gd2O2S:Tb screens in terms of X-ray sensitivity and MTF (modulation-transfer function). The
measurements were performed for a wide range of coverages (34 – 135 mg/cm2) by using a
conventional film radiographic method. In addition, CsI:Tl having columnar structure was also
investigated. |
