<p>A scanning-based arrangement for obtaining imaging data of an object (5) at high repetition rate comprises a support structure (11); scanning-based apparatuses (10) fixedly arranged on the support structure and each including (i) a radiation source (1), and (ii) a radiation detector (6) comprising a stack of line detectors (6a), each being directed towards the radiation source to allow a ray bundle (b1, ..., bn, ..., bN) of radiation to enter the line detector; an object table (13) arranged in the radiation path of one of the scanning-based apparatuses; and a device (14) provided for rotating the support structure relative to the object table so that the object table will successively be arranged in the radiation path of each of the scanning-based apparatuses, during which rotation each of the line detectors in each of the radiation detectors is adapted to record a plurality of line images of radiation as transmitted through the object.</p> |
