[AMD3-1 (Invited)] An Indirect-Conversion Flat-Panel X-Ray Detector Based on Amorphous Silicon 3-D One-Transistor Active Pixel Sensor
Flat-Panel X-Ray Detector, One-Transistor APS, Thin-Film Transistor, Large-Area Imaging
An APS has been proposed for achieving high SNR ratio in X-ray detectors. Since 2015, we have developed a one-TFT APS to obtain high resolution and gain. In this work, a detector with an array of 3840×3072 was developed with an image sensitivity of 280lsb/μGy and a resolution of 6.71lp/mm.
