Journal ArticleDOI
Experimental and Theoretical Evaluation of a High Resolution CMOS Based Detector Under X-Ray Imaging Conditions
Christos Michail,V Spyropoulou,George Fountos,Nektarios Kalyvas,Ioannis Valais,Ioannis Kandarakis,G.S. Panayiotakis +6 more
TL;DR: Fundamental imaging performance in terms of Modulation Transfer Function (MTF), Noise Power Spectrum (NPS) and Detective Quantum Efficiency (DQE) was investigated for a high resolution CMOS based imaging sensor and it was found that the detector response function was linear for the exposure ranges under investigation.
Journal ArticleDOI
In vivo measurement of radius calcium/phosphorus ratio by X-ray absorptiometry
TL;DR: The Ca/P ratio of the radius was significantly lower in patients with postmenopausal osteoporosis than in premenopausal controls.
Journal ArticleDOI
Light emission efficiency and imaging performance of Gd2O2S: Eu powder scintillator under x-ray radiography conditions.
Christos Michail,George Fountos,P. Liaparinos,N. Kalyvas,Ioannis Valais,Ioannis Kandarakis,George Panayiotakis +6 more
TL;DR: In this paper, the authors evaluated Gd 2 O 2 S : Eu powder phosphor as a radiographic image receptor and to compare it to phosphors often used in radiography.
Journal ArticleDOI
The skeletal calcium/phosphorus ratio: A new in vivo method of determination
TL;DR: A new method for assessing the Ca/P ratio of bone in vivo using gamma-ray photon absorptiometry, using two radiation sources and a germanium detector, and the effect of collagen and fat on the measurements was investigated.
Journal ArticleDOI
Light emission efficiency and imaging performance of Lu2O3:Eu nanophosphor under X-ray radiography conditions: Comparison with Gd2O2S:Eu
I. E. Seferis,I. E. Seferis,Christos Michail,Ioannis Valais,Justyna Zeler,P. Liaparinos,George Fountos,Nektarios Kalyvas,S. David,F. Stromatia,Eugeniusz Zych,Ioannis Kandarakis,G.S. Panayiotakis +12 more
TL;DR: In this paper, the authors investigated the imaging and efficiency properties of a 33.3 millimeter Europium-activated lutetium oxide (Lu 2 O 3 :Eu) scintillating screen coupled with a high resolution RadEye HR CMOS photodetector under radiographic imaging conditions.
