Abstract: A detector array (118) for a radiation system includes first and second detector cells (202, 250). The first detector cell (202) includes a first scintillator (220) that converts a radiation photon (226) impinging the first scintillator (220) into first light energy (230), and a first solar cell (212) that converts the first light energy (230) into first electrical energy. The second detector cell (250) includes a second scintillator (270) that converts a radiation photon (276) impinging the second scintillator (270) into second light energy (280). The first scintillator (220) includes a first detection surface (224) through which the radiation photon (226) impinging the first scintillator (220) enters the first scintillator (220). The second scintillator (270) includes a second detection surface (274) through which the radiation photon (276) impinging the second scintillator (270) enters the second scintillator (270).

Abstract: Among other things, one or more techniques and/or systems are described herein for transferring communication information between a stationary unit and a movable (e.g., rotating) unit, or between two movable units without contact between the units. A transmitter is configured to translate digital information into an analog signal which may be fed to an input coupler positioned within a channel of an electrically conductive member (e.g., on a first unit, such as a stationary unit). The current of the signal induces a signal in an output coupler (e.g., on a second unit, such as a movable unit). Voltage characteristics of the induced signal (e.g., which substantially correspond to voltage characteristics of the signal fed into the input coupler) may subsequently be used to reconstruct the digital data at a receiver. In this manner, information can be communicated between two non-contacting units.

Abstract: Power delivery of an image modality system for transferring power from a transmission unit (e.g., stationary unit) to a reception unit (e.g., a moving and/or rotating unit). A modulated electric signal comprising at least two modulated characteristics (e.g., such as amplitude and frequency) is configured to (e.g., concurrently) supply power to both high voltage and lower voltage components (216, 222) of the reception unit. An auxiliary component (316) is configured to utilize a first of the modulated characteristics (e.g., amplitude) to adjust/regulate a voltage applied to the lower voltage component (s), and a filter component (324) (e.g., such as a frequency selective circuit) is configured to utilize a second of the modulated characteristics (e.g., frequency) to adjust/regulate a voltage applied to the high voltage component (s).

Abstract: Among other things, one or more techniques and/or systems are described for reducing a voltage ripple in an electric signal. In this way, in radiographic imaging modalities, for example, undesired fluctuations in an output of a radiation source (e.g., undesirable fluctuations in an energy level of emitted photons) may be reduced. To reduce the voltage ripple, a (ripple reducing) electric signal is generated that comprises properties substantially similar to the voltage ripple, but opposite in phase. The (ripple reducing) electric signal is then combined with the original electric signal to generate a combined electric signal with a voltage ripple that is reduced relative to the voltage ripple of the electric signal as initially generated.

Abstract: A charge transfer system includes a current-based input device for generating an input current signal, a temporary energy storage device, and an amplification device. A switching device couples the temporary energy storage device to the current-based input device during a first portion of a time period and to the amplification device during a second portion of a time period. The input current signal charges the temporary energy storage device, during the first portion of the time period, to generate an input voltage signal. The amplification device receives the input voltage signal during the second portion of the time period.

During a first phase of operation, the isolation device is activated and isolates the integrator from the second charge storage device, and the input charge received on the input terminal of the integrator is stored on the first charge storage device.

Abstract: A data acquisition system for use in a CT scanner comprises an analog-to-digital converter for generating digital signals in response to analog signals representative of projection data taken at a relatively constant sampling rate; and an interpolation filter for generating projection data for a plurality of predetermined projection angles as a function of the digital signals irrespective of the sampling rate.

Abstract: A method and apparatus for performing CT scans of baggage being carried or loaded onto commercial aircraft are described. The CT baggage scanner of the invention includes numerous features which provide the system with high baggage throughput on the order of seven hundred bags per hour as well as improved image quality and accurate target detection. In one aspect, the scanner includes an adaptive image reconstruction window which identifies data collected from the field of view that are not related to the baggage being scanned. These unrelated data are excluded from the image reconstruction process, resulting in greatly reduced reconstruction time and increased baggage throughput. The invention also includes the capability of performing calibration "air scans" with objects such as the system conveyor in the field of view.

Abstract: A measurement and control system for controlling system functions as a function of rotational parameters of a rotating device includes a plurality of interval markers distributed around the periphery of the rotating device and fixed relative to the device support. The measurement and control system also includes a plurality of sensors attached to the periphery of the rotating device, fixed relative to the rotating device so as to be in close proximity to the interval markers. Measurements from sensors attached to different locations on the rotating device are combined so as to mitigate variations in angular speed of the device. Measured rotational parameters are used to predict, via linear interpolation, angular positions of the device between those positions measured by the sensors.

Abstract: A data acquisition system is described for converting a plurality of analog information signals to a corresponding plurality of digital output signals each (a) having a dynamic range of n bits to match the dynamic range of the corresponding analog information signal, and (b) representative of the corresponding analog information signal during each of a plurality of time intervals. The system simultaneously converts each of the analog signals to an intermediate digital signal during each of the time intervals in accordance with a digitization code of m bits (where m is less than n) such that the digitization intervals of the code increase non-linearly so that the ratio of the noise level of the intermediate digital signal and the digitization interval of the code is substantially constant throughout the dynamic range of the analog signals. The intermediate digital signals are transformed to the corresponding digital output signals.
