Abstract

　本発明の放射線検出器１は、検出セル７から出力されるアナログ電気パルスＰを所定のしきい値Ｖｔｈで二値化してデジタル電気パルスＰｐに変調するパルス幅変調器１１と、放射線が入射する検出セル７の位置に関する入射位置パルスＰｘ、Ｐｙと放射線により検出されるデジタル電気パルスＰｐとを重畳して入射位置パルス列Ｐｔを出力するデータ重畳器１３とを備えるので、従来デジタル電気パルスＰｐの出力の後ろに付加されてきた位置情報をデジタル電気パルスＰｐの中に付加することができる。したがって、デジタル電気パルスＰｐの後ろに位置情報を付加して位置情報を伝送する従来技術に比べて、検出セル７に入射する放射線の位置を短い時間で検出することができる。
