  • Patent number: 12159330
    Abstract: Upon receiving list-mode data by detecting radiation emitted from a radiation source positioned with a field of view of a medical imaging scanner, each photon included in the list-mode data can be classified according to one or more interaction properties, such as energy or number of crystals interacted with. Grouped pairs of photons can be generated based on the classifying, and a corresponding interaction-property-specific correction kernel (e.g., a corresponding interaction-property-specific point spread function correction kernel) can be selected for each group. Corresponding interaction-property-specific correction kernels can then be utilized to generate higher quality images.

  • Patent number: 11779296
    Abstract: An apparatus and a method for correcting for signal variations in pixels of a main photoelectric conversion element in a radiation detection apparatus due to focal spot position drifts. Edge reference detectors are positioned next to a main detector, in a fan beam coverage but outside a scan field of view. The signal variations of the edge reference detectors under an anti-scatter-grid shadow are used to estimate a real-time focal spot movement, which is used to estimate a shadow/signal variation on the main detector that are in the scan field of view.

  • Patent number: 11395148
    Abstract: Embodiments of this application relate to a method and a device for protecting privacy. The method includes: sending, by a remote terminal, a first message to a mobility management entity by using a relay terminal, where the first message includes first identity information of the remote terminal, and the first message is used by the mobility management entity to obtain an international mobile subscriber identity IMSI of the remote terminal based on the first identity information of the remote terminal, where the first identity information is a proximity service relay user key identity PRUK ID. Because the first identity information is used to replace the IMSI, interception of the IMSI by the relay terminal is avoided, and user privacy is protected.
