Due to the provision of slit collimators an intensity of a fan beam is reduced significantly such that expensive high power x-ray tubes have to be used. According to an exemplary embodiment of the present invention, a high power tube may be used with a very long focus in combination with a focusing collimator. The tube can be a cheap fixed anode tube still with a high power of, for example, 15 kW due to the large focus. The collimator may ensure that the resolution of the reconstructed scatter function is not degraded. The illuminated slice thickness is increased which may allow for an isotropic spatial resolution.

The invention relates to a mammography accessory for MR elastography which is capable of generating longitudinal oscillations which extend in the longitudinal direction in the mammae of a patient to be examined. The examination time can thus be reduced while at the same time realizing a rendition of the mammae in transverse slice images which is acceptable to examiners.
