  • Publication number: 20170094020
    Abstract: Processing received job requests for a multi-versioned distributed computerized service. For each received job request, the job request is channeled to an appropriate service processing node that depends on the version of the distributed computing service that is to handle the job request. A version of the distributed computing service is assigned to the incoming job request. A service processing node that runs a runtime library for the assigned service version is then identified. The identified service processing node also has an appropriate set of one or more executables that allows the service processing node to plan an appropriate role (e.g., compiler, scheduler, worker) in the distributed computing service. The job request is then dispatched to the identified service processing node.

  • Publication number: 20170090958
    Abstract: Processing a job request for multiple versions of a distributed computing service. The service processing node does this by at least interleavingly (e.g., via time sharing with rapid context switching, or by actually concurrently) running a first runtime library associated with a first service version of the distributed computerized service and a second runtime library associated with a different service version of the distributed computerized service. While running the first runtime library, job requests of a first service version may be at least partially processed using a first set of one or more executables that interact with the first runtime library. While running the second runtime library, job requests of a second service version may be at least partially processed using a second set of one or more executables that interact with the second runtime library.

  • Patent number: 9606199
    Abstract: An automated blood sampling system for PET imaging applications that can be operated in or very near to the field of view (FOV) of an MR scanner, such as in a combined MR/PET imaging system. A radiation detector uses APDs (avalanche photo-diodes) to collect scintillation light from crystals in which the positron-electron annihilation photons are absorbed. The necessary gamma shielding is made from a suitable shielding material, preferably tungsten polymer composite. Because the APDs are quite small and are magnetically insensitive, they can be operated in the strong magnetic field of an MR apparatus without disturbance.

  • Publication number: 20160327657
    Abstract: A detector system for time-of-flight (TOF) positron emission topography (PET) includes an analog silicon photomultiplier (aSiPM) configured to detect at least one photon event. The aSiPM has an anode and a cathode. A transformer has a first side electrically coupled to the aSiPM to form a low-impedance current loop between the anode and the cathode of the transformer. An impedance ratio of the transformer N reduces an effective terminal resistance of the aSiPM. An amplifier is electrically coupled to a second side of the transformer. The amplifier has negative feedback path configured to minimize the voltage swing between a non-inverting input and an inverting input. The negative feedback path reduces an effective terminal capacitance and an effective load impedance of the aSiPM.

  • Patent number: 9442201
    Abstract: Timing pick-off is provided in time-of-flight positron emission using digital output photo sensors (e.g., SPAD or dSiPM). The timing-to-digital converter (TDC) is replaced for timing detection with a mixed analog and digital timing pick-off (MTP) where a processor determines the timing from an output of the MTP. The digital SPAD or dSiPM output is summed into an analog waveform, allowing for triggering based on signal statistics or other than at a particular number of discrete detections. The trigger is used by the processor to extrapolate the time of occurrence without an integrated TDC.
