ABSTRACT:
A scanning-based arrangement for obtaining tomosynthesis 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) 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 that propagates in a respective one of various different angles (α1, . . . , αn, . . . , αN) 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 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 of each of the scanning-based apparatuses is adapted to record a plurality of line images of radiation as transmitted through the object.
