Abstract:
A radiation image recording method, comprising the steps of:i) locating a radiation source and a radiation detector with an object intervening therebetween, ii) locating a set of radiation blocking plates, each of which has at least one slit, between the radiation source and the radiation detector such that the object intervenes between the radiation blocking plates, and such that the slits of the radiation blocking plates are aligned in a straight line with the radiation source, iii) shifting the set of the radiation blocking plates stepwise in a direction along which radiation having been produced by the radiation source scans the object, such that the state in which the slits of the radiation blocking plates and the radiation source are aligned with one another in the straight line is kept, iv) after each step of the shifting, rotating the radiation source, the set of the radiation blocking plates, and the radiation detector around the object, and v) recording radiation image patterns of the object during the rotation.
