Disco 公司制成了 Dr.Robert S.Ledley 设计的全身用 X线断层摄影装置(ACTA Scanner).在不少用计算机处理的断层图象装置中,这是世界上第一台能对人体全身的任何部位作 X 线断层扫描的图象摄影装置,用电子计算机来计算处理断层上的 X 线吸收系数的分布情况,然后用彩色或黑白电视显示出清晰的横断层图象,并且还可以用磁带录象机或拍拉照相机将图象记录下来,图1是这种装置的外形。 Disco Corporation made the whole body with the use of Dr.Robert S.Ledley with the X-ray imaging device (ACTAScanner.)
