  • Publication number: 20180082036
    Abstract: Systems and methods of processing medical device data include receiving streaming time series medical device data. Streaming analytics are applied to the time series medical device data. Streaming analytics identify clinical cases in the streaming time series medical device data. Streaming analytics identify events in the medical device data. An event notifier receives the identified events from the streaming time series medical device data and groups the identified events into notification groups. The event notifications are transmitted for each of the identified events to recipients in the notification groups across communication platforms associated with each of the notification groups.

  • Publication number: 20180078233
    Abstract: There is set forth herein a method including performing with an X-ray detector array of a CT imaging system one or more calibration scans, wherein the one or more calibration scans include obtaining for each element of the first through Nth elements of the X-ray detector array one or more calibration measurements; and updating a spectral response model for each element of the first through Nth elements using the one or more calibration measurements. In another aspect, a CT imaging system can perform imaging, e.g. including material decomposition (MD) imaging, using updated spectral response models for elements of an X-ray detector array. The spectral response models can be updated using a calibration process so that different elements of an X-ray detector array have different spectral response models.

  • Publication number: 20180081014
    Abstract: A PET-MRI system for imaging an object is provided. The PET-MRI system includes a magnetic resonance imaging sub-system, a positron emission tomography sub-system, an optical sensor, and a data processing controller. The magnetic resonance imaging sub-system includes a surface coil that acquires magnetic resonance signals from the object. The positron emission tomography sub-system acquires PET emissions from the object. The optical sensor detects at least one of a spatial location and a shape of the surface coil. The data processing controller communicates with the magnetic resonance imaging sub-system, the positron emission tomography sub-system, and the optical sensor, and utilizes at least one of the detected spatial location and the detected shape of the surface coil to correct the acquired PET emissions for attenuation.
