Abstract: A method for functional visualization and localization of an arteriovenous malformation is proposed. A patient is scanned over a predetermined projection angle range during a contrast agent uptake time. The examination region is reconstructed using the projections over the entire projection angle range. The arteriovenous malformation is localized. The multiplicity of the projections is subdivided into at least three partial projection datasets each belonging to different consecutive time windows of the total duration of the scan. A time series having tomosynthesis image datasets is generated by the partial projection datasets. An arterial and/or venous assignment of the vessels flooded with contrast agent takes place based on the time series of tomosynthesis image datasets.

Abstract: A method for monitoring operation behavior of a component of an industrial plant is provided. Parameter identifiers of operation parameters of the industrial plant are read from an element of a control system of the plant. Some of these parameter identifiers are selected and the selected parameter identifiers are forwarded to an element of the control system. Further, a time of a specified operation of the component is defined and behavior of the selected parameters of the component in the defined time is used as guide model for monitoring selected parameters of the component during component operation.

Abstract: The invention relates to a method and a device for removing respiratory artefacts in invasive blood pressure measurements. The level of CO2 in the expired air is monitored during blood pressure measurement and used to approximate and remove the respiratory artifacts. In one embodiment, the respiratory frequency from the respiratory signal is extracted by identifying the end-tidal CO2 level for each breath. A model is derived for the respiratory artifacts using the respiratory frequency, and the model is subtracted from the measured blood pressure data.

Abstract: A method is for calculating computed tomography pictures from detector data of a CT that uses at least two radiation sources that generate different conical beams. A spatial distribution of attenuation values of a scanned object is reconstructed with the aid of detector data of a first relatively large conical beam. The integral attenuation values that are required to supplement the relatively small conical beam are back calculated from the previously reconstructed data. Finally, a reconstruction of computed tomography pictures is subsequently carried out with the aid of the back calculated integral attenuation data and the measured integral attenuation data of the relatively small conical beam.

Abstract: For processing ATM cells in bidirectional, upstream and downstream data streams in an ATM module, whereby the processing speed is higher than the average cell rate and empty cycles without ATM cells occur in the cell stream, a processing logic of the module—for the purpose of an alternating processing of upstream or downstream cells—makes requests upstream and downstream for empty cycles to an empty cycle controller in order to receive processing time. The cells of the downstream data stream can be separately backed up and released in a buffer and, in this way, downstream empty cycles can be generated. Given a downstream empty cycle request, this request is allowed with priority over a simultaneous downstream request when an empty cycle occurs, and, given a downstream empty cycle request, an empty cycle is released delayed by one cycle length if an upstream request is simultaneously present but is otherwise immediately released.

Abstract: A metering system in a combustion unit having an exhaust-gas chamber and a reducing agent reservoir includes an electrically controllable valve for introducing the reducing agent into the exhaust-gas chamber without using compressed air. The valve has an outlet opening that opens directly into the exhaust-gas chamber. The outlet opening is fluidically connected to the reservoir through the valve. The metering system can be produced with only little technical outlay. The metering system includes a recirculating circuit, and the valve has a holding chamber for the reducing agent. The holding chamber is disposed downstream of the outlet opening in a reducing agent flow direction, and is fluidically connected into the recirculating circuit. The metering system includes a coolant circuit for cooling the valve.

Abstract: A method for fabricating a bit line junction in a DRAM array device which improves the doping profile in the channel region. The method includes contradoping via ion implantation through the bit line contact opening made in the device during processing. This particular doping method increases the concentration of dopants in the channel region on the bit line side of the array, without a corresponding increase of dopants on the buried strap side. Such a doping profile results in an improvement in the off current behavior of the device. Depending on the aspect ratio of the contact opening, tilt angles for the ion implantation are possible and can be adjusted for maximum off current efficiency.
