Abstract:
An indirect, photon-counting X-ray detector capable of detecting the low-energy X-rays includes a scintillator screen that is directly coupled to a two-dimensional optical sensor. A signal filter receives an electrical output signal from the optical sensor and removes high intensity signal contributions therefrom that are indicative of direct interaction between said X-ray signal and said optical sensor. The scintillator screen has a sufficient thickness to ensure a high absorption of incident X-ray photons, and uses phosphor grains with a relatively small grain size. A cooling apparatus in thermal communication with the optical sensor may be used to control its temperature. The signal filter maintains a running average of changes in measured pixel output values for consecutive measurements, and replaces a measured value caused by a direct interaction event with a value equal to a previous measured value plus said running average.

Claim (Index 1):
A two-dimensional, indirect photon-counting X-ray detector for an analytical X-ray system comprising:\n a scintillator screen that absorbs an incident X-ray signal in a two-dimensional detection area and emits an optical signal in response thereto that has a common spatial distribution with the incident X-ray signal; a two-dimensional optical sensor coupled directly to the scintillator screen that detects said optical signal emitted thereby and generates an electrical output signal indicative of said spatial distribution of the detected optical signal; and a signal filter that receives the electrical output signal and removes high intensity signal contributions therefrom that are indicative of direct interaction between said X-ray signal and said optical sensor.
