一次多体层摄影原理首先是由Ziedes des Plantes于1933年提出,之后Manoel de Abreu和Sonnott等又在补充了一次多体层摄影技术的有关理论后设计了多种多层暗盒并付诸临床应用。一次多体层摄影的操作较简单,即在一个特殊暗盒内,放有多层胶片,在一次暴光后暗盒中所有胶片均可受到照射。所以它和单体层的唯一区别主要在暗盒。暗盒上面的 A principle of multi-slice photography was first proposed by Ziedes des Plantes in 1933. After that, Manoel de Abreu and Sonnott designed a variety of multi-layer cassettes and put them into clinical application after supplementing the related theory of multi-slice photography . A multi-slice photography is easier to operate, ie in a special cassette with multiple layers of film, all the film in the cassette can be exposed after an exposure. So the only difference between it and the monolayer is in the cassette. Above the cassette
