Abstract: An interventional X-ray system is proposed, the system including a multi X-ray source unit positioned below a patient table. This ‘multiblock’ may comprise several x-ray sources with focal spot positions distributed along the x-y (table) plane. The x-ray sources are operable in a switching scheme in which certain x-ray sources may be activated in parallel and also sequential switching between such groups is intended. The switching may be carried out so that several images with different projection angles can be acquired in parallel. In other words, an optimal multi-beam X-ray exposure is suggested, wherein fast switching in one dimension and simultaneous exposure in the 2nd dimension is applied.
