Abstract: Among other things, one or more techniques and/or systems are described for counting detection events on a detector cell of a photon counting detector array. An electronics arrangement of the detector cell comprises a digital discriminator which is configured according to an impulse response of the detector cell or, more particularly, an impulse response of a radiation detection element of the detector cell (e.g., where the radiation detection element is configured to convert energy of the radiation photon into electrical charge). The digital discriminator is configured to analyze a digital representation of a voltage signal of the detector cell and to compare a result of the analysis to one or more metrics derived based upon the impulse response of the detector cell to identify voltage pulses of the voltage signal that are indicative of detection events.

Abstract: A CT scanning system may include a multi-pixel x-ray source, and a detector array. The multi-pixel x-ray source may have a plurality of pixels that are disposed along a z-axis, and that are sequentially activated so as to controllably emit x-rays in response to incident electrons. The detector array may have one or more rows of x-ray detectors that detect the x-rays that are emitted from the pixels and have traversed an object, and generate data for CT image reconstruction system. In third generation CT scanning systems, the number of detector rows may be reduced. Multi-pixel x-ray source implementation of saddle curve geometry may render a single rotation single organ scan feasible. Using a multi-pixel x-ray source in stationary CT scanning systems may allow x-ray beam design with a minimal coverage to satisfy mathematical requirements for reconstruction.

Abstract: Among other things, an object scanner, such as an x-ray system, is provided, where the object scanner is configured to translate an object undergoing an examination along a non-linear path. For example, in some embodiments, an examination region of the object scanner is spatially offset, relative to an entry port and/or an exit port of the object scanner, such that there is little to no line of sight through the object scanner, from the entry port to the exit port. The non-linearity of the path is configured to reduce the possibility of radiation scatted by an object and/or by portions of the object scanner from escaping the examination region and exiting the object scanner via the entry port and/or the exit port.

Abstract: Among other things, one or more techniques and/or systems for correcting projection data representative of an object under examination to account for drift in a radiation system are provided. System drift is measured by performing a drift calibration on the radiation system. During the drift calibration, a temperature of the radiation system is measured and one or more calibration tables, such as an air table and/or offset table, are corrected based upon the measured temperature to derive a theoretical projection (e.g., indicative of measurements that are expected to be acquired from the radiation system during the drift calibration). The theoretical projection is compared to an actual projection acquired during the drift calibration to measure a degree of drift. Based upon the measured degree of drift, one or more correction factors are determined to correct and/or otherwise adjust for system drift in a projection respective of the object.

Abstract: Among other things, one or more techniques and/or systems are described for setting a sampling frequency for a radiation imaging system. The radiation imaging system comprises a rotating gantry configured to rotate a radiation source and a detector array about an object to generate an image(s) of the object. A data acquisition system is configured to sample the detector array as views. One or more flag structures are arranged according to a partial arc segment (e.g., a structure less than a full 360 degree circle). One or more sensors are disposed on one of the rotating gantry or a stationary support about which the rotating gantry rotates. When a sensor encounters a flag structure, a current rotational speed of the rotating gantry is determined. A clock frequency is updated based upon the current rotational speed to establish a sampling frequency for the data acquisition system for sampling the detector array.
