  • Patent number: 10743830
    Abstract: A method and apparatus is provided to correct for scatter in a positron emission tomography (PET) scanner, the scatter coming from both within and without a field of view (FOV) for true coincidences. For a region of interest (ROI), the outside-the-FOV scatter correction are based on attenuation maps and activity distributions estimated from short PET scans of extended regions adjacent to the ROI. Further, in a PET/CT scanner, these short PET scans can be accompanied by low-dose X-ray computed tomography (CT) scans in the extended regions. The use of short PET scans, rather than full PET scans, provides sufficient accuracy for outside-the-FOV scatter corrections with the advantages of a lower radiation dose (e.g., low-dose CT) and requiring less time. In the absence of low-dose CT scans, an atlas of attenuation maps or a joint-estimation method can be used to estimate the attenuation maps for the extended regions.

  • Publication number: 20200240970
    Abstract: Systems and methods which use an optical sensor and an electromagnetic sensor in cooperation for detecting concentrations of one or more materials in solutions are described. In operation according to embodiments of a cooperative optical and electromagnetic sensor material concentration detector, both an optical sensor and electromagnetic sensor are used in cooperation to detect a concentration of a material having a physical feature that is otherwise incompatible with one or the other sensors and/or a material for which measurement is affected by another material present in the sample. Embodiments are, for example, configured to provide a cooperative implementation of optical and electromagnetic sensors operable to detect concentrations of metal ions and acid in a solution, such as for use in real-time material concentration detection.

  • Publication number: 20200211350
    Abstract: A system and a method for attack detection includes a constellation of beacons, wherein each beacon is adapted to broadcast a unique beacon identification code (beacon ID); a terminal device adapted to receive a user trace of beacon IDs, and send a query to a backend server or routing device to determine an occurrence of an intrusion via a network; wherein the backend server is adapted to determine an occurrence of an intrusion by carrying out the steps of: computing spatial relational metrics between beacon devices; transforming beacon IDs as states of a Markov chain model, and estimating state transition probabilities based on the spatial relational metrics; recording user traces of beacon ID transitions when terminal device make queries; and running hypothesis test on the user traces against the Markov chain model to determine a status of intrusion.

  • Publication number: 20200211154
    Abstract: Various embodiments of a vision-based privacy-preserving embedded fall-detection system are disclosed. This embedded fall-detection system can include one or more cameras for capturing video images of one or more persons. Moreover, this embedded fall-detection system can include various fall-detection modules for processing the captured video images including: a pose-estimation module, an action-recognition module, and a fall-detection module, all of which can perform the intended fall-detection functionalities within the embedded system environment in real-time in order to detect falls of the one or more persons. When a fall is detected, instead of sending the original captured images, the embedded fall-detection system can transmit sanitized video images to the server, wherein each detected person is represented by a skeleton figure in place of the actual person images, thereby preserving the privacy of the detected person.

  • Publication number: 20200202588
    Abstract: A method and apparatus is provided to iteratively reconstruct a computed tomography (CT) image using a spatially-varying content-oriented regularization parameter, thereby achieving uniform statistical properties within respective organs/regions and different statistical properties (e.g., degree of smoothing and noise level) among the respective organs/regions. For example, less smoothing and sharper features/resolution can be applied within a lung region than within a soft-tissue region by using a smaller regularization parameter value in the lung region than in the soft-tissue region. This can be achieved, e.g., using a minimum intensity projection to suppress/eliminate sub-solid nodules in the lung region. The content-oriented regularization parameter can be generated by reconstructing an initial CT image, which is then segmented/classified according to organs and/or tissue type.
