The invention relates to an imaging arrangement 1 for obtaining imaging
data of an object 7. The imaging arrangement 1 comprises a support
structure 3 having an axis of rotation 9 and comprising means 10 for
rotating the support structure 3; a pair of first and second radiation
modules 2a, 2b fixedly arranged on the support structure 3 along a radius
perpendicular to the axis of rotation 9, wherein each of the radiation
modules 2a, 2b comprises a radiation source 6a, 6b simultaneously
emitting radiation; a radiation detector 4 for detecting radiation as
emitted from the radiation modules 2a, 2b and passed through the object 7
being imaged; and a collimator 14 arranged between, as seen in a
direction parallel to the axis of rotation 9, the pair of radiation
modules 2a, 2b and the radiation detector 4. The invention also relates
to a corresponding method.
