CMOS image sensors, also known as CMOS Active Pixel Sensors (APS) or Monolithic Active
Pixel Sensors (MAPS), are today the dominant imaging devices. They are omnipresent in …

Digital x-ray detectors are now the detector of choice in many X-ray examinations. They
have been accepted into clinical practice over the past decade but there are still ongoing …

This article presents a 5.2-Mpixel, 12-in wafer-scale CMOS X-ray detector that consists of
lithographically stitched 169 sub-chips. The detector employs a 3T pixel with a voltage …

The ability of wafer scale Complementary Metal Oxide Semiconductor (CMOS) imagers to
integrate sensing with analogue to digital conversion at the pixel level has led to their …

Recently CMOS active pixels sensors (APSs) have become a valuable alternative to
amorphous silicon and selenium flat panel imagers (FPIs) in bio-medical imaging …

This paper presents a CMOS X-ray detector with 14.3-bit column-parallel extended-counting
analog-to-digital converters (EC-ADCs). The CMOS X-ray detector employs column-parallel …

In this paper, we describe the architecture of a wafer-size CMOS image sensor enabling to
enlarge the size of the large-format sensor while maintaining good signal quality. The good …

This paper proposes a CMOS flat-panel X-ray detector (FPXD) with dual-gain active pixel
sensors (APSs) and column-parallel readout circuits to reduce the random noise. The …

This paper presents a low-power and low-noise tileable CMOS X-ray line detector with time-
delay-integration (TDI) for large-sized dental X-ray imaging systems. The proposed X-ray …

For 2-d X-ray imaging, such as mammography and non-destructive test, a sensor should
have a large-area because the sensor for typical X-ray beams cannot use optical lens …
