Abstract: A resonant power converter. An embodiment with a fullbridge converter is disclosed, controlled with feedback or feedforward technique. Switching schemes are either based on a sort of look up table or on measurement of current or voltage. Dead time may be adjusted. Timing may be such, that in the respective diagonal pairs of the converter, one switch is switched on for a different time (different pulse width) than the other. Use in a relative high power environment for about 20KW in e.g. an X-Ray or Computer Tompgrapy System.

Abstract: Among other things, one or more techniques and/or systems for counting detection events via a photon counting detector array is provided. A first instance where an amplitude of an electrical signal exceeds an event threshold is detected. The first instance is generated responsive to a first detection event at a detector cell. An event counter is disabled from counting other detection events at the detector cell for a first blocking interval. At a conclusion of the first blocking interval, the amplitude of the electrical signal is determined Responsive to determining that the amplitude of the electrical signal is below the event threshold, an adjustment is made to an event count based upon the first detection event. Responsive to determining that the amplitude of the electrical signal exceeds the event threshold, the event counter is disabled from counting other detection events at the detector cell for a second blocking interval.

Abstract: Among other things, one or more techniques and/or systems are described for defining imaging modes and for operating a photon counting radiation imaging system. A set of imaging modes with different counting schemes may be defined such that counting schemes will count detection events of a set of radiation events in different manners. For example, a first counting scheme may count primary detection events in a primary counter and secondary detection events in a secondary counter. A second counting scheme may count primary and secondary detection events in the primary counter. A third counting scheme may merely count detection events occurring within a primary detector cell associated with the primary counter. A fourth counting scheme may combine energy of detection events into merged energy. A selected imaging mode may be applied to the photon counting radiation imaging system in order to achieve desired image scanning characteristics (e.g., spatial resolution, dose savings, spectral ability).
