Dual-Gate Photosensitive Thin-Film Transistor-Based Active Pixel Sensor for Indirect-Conversion X-Ray Imaging

  title={Dual-Gate Photosensitive Thin-Film Transistor-Based Active Pixel Sensor for Indirect-Conversion X-Ray Imaging},
  author={Kai Wang and Hai Ou and Jun Chen},
  journal={IEEE Transactions on Electron Devices},
Over the past century, the conventional film-based radiographic X-ray imaging has evolved into digital radiography (DR). Amorphous silicon thin-film transistor (TFT)-based flat panel X-ray detector was introduced two decades ago, and has become a ubiquitous platform for several imaging modalities, including chest radiography, mammography, and fluoroscopy. As a fundamental building block, an advanced pixel has thus been developed to tackle clinical challenges. However, all types of pixel… CONTINUE READING
