  • Patent number: 10687732
    Abstract: Provided is a method of selecting a slice configuration of a medical imaging apparatus. According to an example, an expected scanning time for scanning a region of a scanning length by the medical imaging apparatus with each of candidate slice configurations may be determined, and one or more first slice configurations are selected from the candidate slice configurations in a way that the scanning time of each of the first slice configurations is less than a preset threshold. An expected scanning length and an expected redundant scanning dose for scanning the region by the medical imaging apparatus with each of the first slice configurations may be determined. In this way, for scanning the region by the medical imaging apparatus, a target slice configuration may be selected from the first slice configurations according to the expected redundant scanning dose.

  • Patent number: 10690783
    Abstract: A radon measurement device includes a housing, a diffusion chamber, a diffusion chamber sensor, a diffusion pathway, a clock circuit, measurement circuitry, and a triggering mechanism. The diffusion chamber is disposed in an internal cavity of the housing. The housing includes a vent. The diffusion chamber sensor detects radioactive decay of radon and generates an electrical signal. The diffusion pathway enables introduction of ambient air into the diffusion chamber. The clock circuit outputs time data. The measurement circuitry receives the electrical signal and associates therewith a particular time datum. The triggering mechanism selectively isolates the vent from an environment and selectively triggers the measurement circuitry. Responsive to a triggering action on the triggering mechanism, the diffusion pathway is fluidly connected with the environment and functionality of the measurement circuitry is initiated.

  • Patent number: 10684199
    Abstract: The present disclosure is directed to an improved method for distinguishing tissue from an embedding medium, such as paraffin in a formalin-fixed paraffin-embedded sample. The method involves the use of fluorescence of naturally-occurring species in tissue to determine the location of the tissue in the embedded sample. An embedded sample is generally excited by light of a selected wavelength, and the fluorescence emission at an emitted wavelength is used to locate the boundary or location of the tissue in the embedded sample.

  • Patent number: 10667693
    Abstract: Aspects of the present disclosure provide systems, methods, devices, and computer-readable media for interference filter correction based on angle of incidence. In some examples, a sample emits an emission spectrum that is filtered by an emission filter to provide a transmission spectrum. The emission spectrum illuminates the emission filter at multiple angles of incidence. The angles of incidence result in a spectral shifting of the transmission spectrum. Based on this spectral shifting, the intensity of the transmission spectrum is corrected. An image corresponding to the corrected intensity of the transmission spectrum may be generated.

  • Patent number: 10670512
    Abstract: The Intrinsic Hyper-Spectral Flow Cytometer (IHSFC) and its associated methodology, improves current flow cytometry by eliminating the need of associated hardware-based elements currently used for spectral data detection. The (IHSFC), rather than using narrow band lasers to excite or interrogate the analytes, the flow stream is excited by a wide wavelength range beam. The raw data generated by the (IHSFC) are as follows; forward light scatter, right angle light scatter, coherent spectral data and non-coherent spectral data. The intrinsic fluorescent spectral components are extracted from the coherent and non-coherent spectral data.
