摘要：

Signal measurements for a variety of pixelated a-Si:H imaging arrays irradiated by megavoltage beams are reported. Data are presented for 6, 10, and 15 MV beam energies for screens containing gadolinium-oxysulfide and calcium tungstate. These results are the first quantitative radiation signal sizes reported for such arrays. In addition, the initialization times of these arrays are reported. The performance of arrays of various sizes and pitches with respect to these measured values is compared. These results are part of an on-going effort by our collaboration to develop flat-panel, real-time, gamma and x-ray imagers.
