Abstract / Description of output

We present the first reported use of a CMOS Single Photon Avalanche Diode (SPAD) array for the detection of high energy photons (X-rays), utilizing a 3D-stacked backside-illuminated (BSI) SPAD image sensor, and cabinet biological X ray irradiator. We detected photon peak energies from 30 to 160 keV. Furthermore, increasing the SPAD bias voltage results in increased X-ray detection. This unveils new applications of CMOS SPADs in X-ray detection and imaging.
