摘要
An apparatus for planar beam radiography comprises an ionizing radiation source and an ionizing radiation detector; the ionizing radiation source being line-like and extending substantially in a first direction; and the ionizing radiation comprising an elongated radiation slit entrance extending substantially in a second direction and being arranged for one-dimensional detection of radiation from the radiation source entering the detector through the radiation slit entrance. According to the present invention the radiation source and the radiation dectector are oriented such that the first and second directions are essentially perpendicular. Hereby,a facilitated alignment of the detector with respect to source is achieved.
