摘要： For the transmission of an MBMS content to a plurality of user equipment units, the use of a p2m channel may only be beneficial if the number of joined user equipment units exceeds a threshold. However, counting is made difficult due to the fact that any idle mode UE, also a non joined UE, may reply to the notification, and hence pretend a higher number of UEs which are ready and able to receive the MBMS content. According to the present invention, when joining the MBMS service, a number which is only known to the user equipment unit, as well as to those RNCs which will deliver the MBMS service for which the UE has joined, is provided to the UE. Whenever the UE replies to a service notification, it uses this number. The RNC determines a corresponding number and in case the number received from the UE matches the number determined by the RNC, the UE is counted. Advantageously, an integrity protection may be provided for the notification reply for joined UEs which are still in the idle mode.

摘要： An apparatus includes a scale factor determiner (236) that determines a count scale factor based on a measured count of a number detected photons for an energy threshold and an estimated actual count of the number of detected photons. The photons include poly-energetic photons detected by a radiation sensitive detector. The apparatus further includes a count sealer (136) that employs the count scale factor to scale measured counts of detected photons for different energy thresholds.

摘要： Scattered radiation has non-intuitive properties. A signalling system (28) is presented which provides a perceptible signal (34) being indicative of a predicted or measured spatial distribution of scattered radiation. An embodiment provides for easy assessment of the individual risk of scattered radiation exposure for personnel working in an environment exposed to scattered radiation. A method for predicting a distribution of scattered radiation takes into account at least one object related parameter (18) and at least one radiation related parameter (22) and, in response hereto, predicts a distribution of scattered radiation.

摘要： The invention is directed at an apparatus (10), an imaging device and a method for detecting X-ray photons, in particular photons (32,34) in a computer tomograph. Photons (32,34) are converted into an electrical pulse and compared against a threshold using a discriminator (20). The electrical network (12) performing these functions comprises a switching element (28), that can modify the electrical path (22) along which the process signals travel. The trigger signal (VT) for actuating the switching element (28) is derived from an electrical state of the electrical path (22). If a pulse associated to a photon (32,34) is detected, the switching element (28) is actuated in order to avoid that the processing of the charge pulse stemming from a first photon (32) is affected by a subsequent second photon (34).

摘要： Systems and methods for data acquisition in computed tomography (CT) applications are provided. The systems and methods are particularly adapted for scanning and acquiring/processing data in connection with high-power cone-beam CT applications. The electron beam is moved/scanned along the anode surface to multiple focal positions. Data acquisition for a full projection at one focus position and one view angle is achieved by activating each focus position multiple times during the data acquisition for one angle of the gantry. The detector array and associated data processing system are adapted to rapidly switch between the different focus positions during the acquisitions for one view angle and to collect all data belonging to the same projection into the same data set. Adaptive electron optics are utilized to move/scan the electron beam along the anode surface to the various focus positions. Alternatively, a plurality of cathodes may be provided for respective focus positions and the system may support fast switching therebetween to achieve desirably short spot times. The disclosed CT system permits greater power densities without risk of heat damage to the anode and effectively increases the track velocity of the electron beam on the anode surface. The CT system and associated data acquisition methods have particular utility in CT applications requiring increased time resolution and/or spatial resolution, e.g., cardiac CT applications.

摘要： Computed tomography (CT) systems are provided that utilize x-ray tube spectra in connection with the generation and/or interpretation of CT data. The disclosed systems and methods use x-ray tube spectra associated with CT systems to enhance contrast and/or image quality, e.g., by making use of energy selective detection techniques. The x-ray spectra may be determined in a variety of ways, e.g., incorporation of a spectral x-ray tube model into the CT system, using the output of Monte-Carlo simulations, and/or processing measured experimental spectral tube data for the CT system. The x-ray tube spectra is generally generated by and/or stored in a computer system associated with the CT system and may be used in support of an energy selective detective method and/or generation of spectral CT images.

摘要： In UMTS, quality of service attributes, which a user equipment can prescribe for an end-to-end service to be set up in order to meet a specific quality of service, in most cases have to be processed by a central call and admission control function in the network. These quality of service attributes have to be made known to the admission functions of all possible path-segments. Advantageously, according to an exemplary embodiment of the present invention, a quality of service attribute is only transmitted to a selected number of network nodes at the edge of the network. The selected and limited number of network nodes perform a quality of service operation triggered by a receiving station. Advantageously, this may result in a reduction of data traffic and an improved implementation and standardization process. Furthermore, the quality of service attribute may be added to an obligatory configuration message, thus even further reducing the data traffic.

摘要： The invention relates to a method for controlling the transmission power employed by a transmitting unit for transmitting multicast signals via a radio interface to communication devices of a multicast group using a single physical channel. In order to enable an efficient power control, it is proposed that at least the communication device receiving the weakest multicast signals transmits power control commands to the transmitting unit. Further, it is proposed that the transmitting unit adjusts the transmission power based on power control commands received from at least one of the communication devices in a way that the power control commands of the communication device receiving the multicast signals with the lowest quality have the most significant influence on the adjustment. The invention relates equally to a corresponding transmitting unit, to a corresponding communication device and to a corresponding communication system.
