Abstract: In an embodiment, an X-ray imaging apparatus includes an X-ray radiation source to emit X-ray radiation, an object to be sampled being within a receiving region; a converter for spatially resolved conversion of X-ray radiation, after passing through the receiving region, into visible light; a detector, to emit a detector signal based upon visible light from the converter registered by the detector; a pattern generator, to realize a large number of light and shadow patterns (LSPs) in a time-staggered manner by acting on visible light generated by the converter, respective detector signals being generated based upon respective LSPs; and at least one processor, to generate the image of the object based upon the detector signals generated and an item of information about the LSPs. The pattern generator device is configured to generate the large number of LSPs by at least one of overriding and partial shadowing of the visible light.

Abstract: A method is provided for introducing a liquid into a depression of a sample holding plate by way of a controllable dispensing apparatus. The process of the introduction of the liquid is divided into the introduction of a first liquid volume and the introduction of a second liquid volume. A dispensing apparatus is also provided for introducing a liquid into a depression of a sample holding plate. The dispensing apparatus includes a control device that controls an actuator such that a first liquid volume and a second liquid volume are discharged out of an opening of a dispensing head.
