We report on the design and characterization of a monolithic single-photon-counting (SPC) X-ray detector integrating an amorphous semiconductor sensor. Our prototype combines amorphous selenium (a-Se), a well-known photoconductor, with a CMOS readout

We demonstrate the use of pulse-height spectroscopy (PHS) to extract the internal electric field of an amorphous-selenium (a-Se) detector having a polyimide (PI) blocking layer. PHS enables more accurate measurement of the internal electric field of

Practical photon counting detectors that have been adopted for commercial use are typically based on crystalline or polycrystalline materials. However, these types of materials are challenging to scale to large-area medical imaging applications becau

We report, for the first time, results from a single-photon-counting X-ray detector monolithically integrated with an amorphous semiconductor. Our prototype detector combines amorphous selenium (a-Se), a well-known X-ray photoconductive material suit

Amorphous selenium (a-Se) is a direct conversion photoconductor capable of very high spatial resolution that can enable early detection of small and subtle lesions. A-Se also offers cost effective and reliable coupling to large area readout circuitry

Using electric field to partition the selenium layer into a low field charge drift region and a high field avalanche gain region was first proposed in 2005 (1) . Engineering and fabricating such a grid structure on a TFT array have been a challenge.

Summary A least-squares-based adaptive algorithm with forgetting factor is proposed for localization of a target by a mobile distance measurement sensor. This problem, in its most general form, was tackled in a recent paper using a gradient adaptive

In this study, we focus on the problem of localizing an implant or a capsule device in the human body by a mobile sensor unit using distance measurements. As a particular distance measurement technique, time of flight (TOF) based approach involving u

This paper focuses on the problem of localizing a signal source by a mobile sensory agent using distance measurements. This problem was tackled in a recent paper using a gradient based adaptive algorithm. In this paper, we design a least-squares base
