摘要：

In this paper, we discuss a new X-ray imaging detector which consists of lead iodide polycrystalline films as sensor and amorphous silicon flat panel arrays as read out. We present our investigation of such a detector in 5 cm x 5 cm format with 100 mum pixels. The signal amplitude, and sensitivity of the films have been measured along with spatial resolution properties such as line spread function (LSF) and modulation transfer function (MTF). Real-time imaging performance at 30 frames/s of lead iodide films has also been evaluated using vidicon tube approach. Important properties of lead iodide film are also discussed. Finally, the potential applications of this detector are analyzed. (C) 2001 Published by Elsevier Science B.V.
