TL;DR: In this paper, the authors presented room temperature measurements on 200 /spl mu/m thick GaAs pixel detectors, which were hybridized to silicon readout circuits for X-ray applications.

Evaluation of 320×240 pixel LEC GaAs Schottky barrier X-ray imaging arrays, hybridized to CMOS readout circuit based on charge integration
R. Irsigler,J. Andersson,J. Alverbro,J. Borglind,Ch. Fröjdh,P. Helander,S. Manolopoulos,Val O'Shea,Kevin M. Smith +8 more
TL;DR: In this paper, a detector chip was based on semi-insulating LEC GaAs material and had a pitch of 38 μ m. The detector wafers were thinned down prior to the fabrication of the ohmic back contact after dicing, the chips were indium bump, flip-chip bonded to CMOS readout circuits based on charge integration, and finally evaluated.

New sensors for dental X-ray imaging
Christer Fröjdh,J. Andersson,Richard Bates,M Heuken,R. Irsigler,C. S. Petersson,Val O'Shea,Kevin M. Smith,H. Stamatakis,U. Welander +9 more
TL;DR: In this article, the authors present some of the research going on in order to develop new X-ray imaging sensors with improved sensitivity, which are based on a silicon CCD coated with a scintillating material.

320×240 GaAs pixel detectors with improved X-ray imaging quality
R. Irsigler,J. Andersson,J. Alverbro,Z. Fakoor-Biniaz,Ch. Fröjdh,P. Helander,H. Martijn,D. Meikle,M. Östlund,Val O'Shea,Kevin M. Smith +10 more
TL;DR: In this paper, gain and offset corrections for GaAs X-ray pixel detectors, which were hybridized to silicon CMOS readout integrated circuits (ROICs), were reported. And the improvement in image quality was demonstrated in the measured signal-to-noise ratio of flood exposure images.
