METHOD AND DEVICE FOR COLLIMATING AN ENERGY INPUT BEAM

摘要

An irradiation method, in particular for imaging a region of investigation (2) of an object (1), comprises the steps of generating at least one energy input beam (3) with at least one energy input beam source (210), wherein the at least one energy input beam (3) comprises a plurality of individual en­ergy input beam components (3.1, 3.2, 3.3, ...), and irradi­ating the region of investigation (2) with the at least one energy input beam (3) along a plurality of projection direc­tions, wherein the energy input beam components (3.1, 3.2, 3.3, ...) are formed with at least one beam mask (211) made of an energy input shielding material with through holes. Furthermore, an imaging method and devices for irradiating or imaging the object are described.
