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.
摘要:
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 power meter comprises at least two measurement paths and distribution device. A first measurement path contains at least one pre-amplifier and a first detector. A second measurement path contains at least one direct connection and a second detector. An additional third path alternative to or optional to the second path contains at least one attenuation element and a second or respectively third detector. The distribution device distributes a test signal to the measurement paths.
摘要:
An approach is provided for correcting the feedback from electrical measurement converters to the device under test in the case of measurements in the high-frequency and/or microwave range. At least three measurements are implemented with respectively different input impedances of the measurement converter, and that the feedback-free measured value is then calculated from these.
摘要:
A method for the error correction of a vectorial network analyzer, where a primary system calibration is initially implemented using a calibration kit. Following this, a first, secondary error correction is implemented on at least two one-port networks of the vectorial network analyzer. After this first, secondary error correction of the one-port networks of the vectorial network analyzer, a second, secondary error correction is implemented, where either two one-port networks are through-connected in an ideal manner or a measurement is implemented on a reciprocal two-port network. The corrected system-error values from the first, secondary error correction are used even in this further measurement, and overall, a high-precision, calibrated multi-port network analyzer is obtained.
