摘要： A tomography system with a beam source and a detector that is adapted to carry out a scan. While the beam source is guided along a circular or helical first trajectory about an orbital axis, a rectangular sensor surface of the detector is guided at a distance from the beam source along a circular or helical second trajectory about the orbital axis. During the scan, a yaw angle between a perpendicular bisector of the sensor surface and the plane of rotation in which the beam source is currently located has a value of greater than 0° and simultaneously smaller than 90°.

摘要： A tomography installation is configured to carry out a first scan along a first helix-segment-shaped trajectory section and to carry out a second scan along a second helix-segment-shaped trajectory section. A first data set is obtained during the first scan, and a second data set is obtained during the second scan. Taken by themselves in each case, both the first data set and the second data set are too incomplete for a reconstruction of a volume image without a partial revolution artifact. From the two data sets, a fused three- or four-dimensional data set is generated that is sufficiently complete for a reconstruction of a volume image without a partial revolution artifact.

摘要： A circuit converts an analog read channel signal to a digital data signal. A read channel error detector generates an error signal in response to an error in an analog read channel signal. In a set of parallel switches, each parallel switch is connected in series to a pullup resistor and a DC voltage source. A selected parallel switch changes state in response to the error signal so as to provide an adjusted analog read channel signal. A first input of a comparator is coupled to the set of switches, while a second input of the comparator is maintained at a reference voltage. The comparator outputs a digital data signal in response to the adjusted analog read channel signal.
