A detector module is disclosed, having an array of detector elements and a printed circuit board. The printed circuit board includes a first region for holding the array of detector elements and includes at least one second region, angled off relative to the first region. On this at least one second region, signal-processing electronics may be arranged. The vertical design of the detector module allows the design of an area detector to be produced on the basis of a multiplicity of detector modules arranged next to one another. The area detector may be provided for a computer tomograph.

A detector module for a radiation detector is disclosed. In at least one embodiment, the detector module includes a converter layer with contacts, arranged distributed over an area on the rear side, for transmitting electrical signals, wherein the contacts are routed, by way of rewiring, to target contacts on a target region that is smaller than this area. This provides the conditions for simple and secure signal routing between the contacts on the converter layer and readout electronics. In particular, this is successful if a substrate layer used for stabilization purposes has a cutout for the target region, through which cutout the target contacts are directly connected to the signal-routing lines of readout electronics.

A method is disclosed for acquiring measured data by way of a computed tomography system, wherein the measured data is acquired by a detector unit disposed opposite the radiation source during a rotation of a radiation source around an examination object. In at least one embodiment, the rotation is subdivided into succeeding time segments during each of which measured data is acquired, and each of the succeeding time segments has either a first length or a second length consisting of two predefined lengths.

A tool for the ESD-safeguarded mounting of a detector module is disclosed. The tool includes an accommodating element for accommodating at least one module plug of the detector module, in which case it is possible, when the module plug is accommodated, for an electrostatic charge on the detector module to flow away by way of an electrical connection between the module plug and an ESD-safeguarded operator actuating the tool. As such, it is not necessary to intentionally touch module-side contact-making devices of the module plug, and/or the risk of damage to the signal-processing electronics, which are to be brought into contact with the detector module, as a result of overvoltages is avoided.

A grid module of a scattered-radiation grid is disclosed. The scattered-radiation grid includes a number of grid modules disposed next to one another with a plurality of webs, especially for use in conjunction with a CT detector, a CT detector and a CT system with such a detector. In accordance with an embodiment of the invention, at the joining surfaces of the grid modules, the webs located there are provided with breakthroughs to compensate for a disproportionate reduction in scattered radiation.
