Abstract: A method is provided for running a collision protection system for a medical operating device, which has a patient bed for a patient to be operated on, an image recording device having at least one movable image recording component for recording image data of the patient during the operation, and an assistance robot having a movable assistance component which during the operation is situated at least temporarily inside the patient and/or is coupled in terms of movement to an instrument situated inside the patient. In the method, an item of criticality information is determined which describes the criticality of possible collisions of components of the operating device and/or movements of the patient with regard to the interaction of the assistance robot with the patient. Depending upon the criticality information, when a criticality criterion indicating a raised criticality, (e.g.

Abstract: 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°.

Abstract: 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.

Abstract: 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.
