Abstract: A computer-tomography (CT) imaging system, comprising an imaging data acquisition system. The imaging data acquisition system includes a plurality of sets of a detector section, a storage section, and an aggregation section. The detector section includes a plurality of detector elements each being configured to convert radiation into electric signals. The aggregation section is configured to aggregate imaging data carried by the electronic signals from the detector section. The storage section is connected with an output of the detector section and an input of the aggregation section. The storage section comprises a predetermined number of non-volatile memories to store the imaging data from the corresponding detector elements.

Abstract: A micro gas turbine has a compressor and a turbine, the rotors of which are arranged on a common driveshaft. The aim of the described system is to provide a lightweight and inexpensive micro gas turbine. This is achieved in that the driveshaft is mounted using at least two rolling bearings, one of which is arranged in the vicinity of the compressor rotor and one of which is arranged in the vicinity of the turbine rotor. The drive shaft is designed in a hollow manner, the inner hollow space of the driveshaft being filled with an evaporable coolant.
