  • Patent number: 11118981
    Abstract: A metasurface integrated microbolometer having a sensing layer (e.g., SixGeyO1-x-y). The presence of the metasurface provides selectivity with respect to wavelength, polarization and angle-of-incidence. The presence of the metasurface into the microbolometer affects conversion of electromagnetic to thermal energy, thermal response, electrical integration of the microbolometer, and the tradeoff between resistivity and temperature coefficient of resistance, thereby allowing the ability to obtain a sensing with high temperature coefficient of resistance with lower resistivity values than that of films without the metasurface. The presence of the metasurface removes the need for a Fabry-Perot cavity.

  • Patent number: 11076820
    Abstract: A tomosynthesis system has an x-ray source with an addressable array of electron emitting sections on the cathode. The x-ray source moves rotationally about an imaging target, such as a breast. During the rotation, x-rays are emitting from the x-ray source while the x-ray source continues to move. During the emission of x-rays, different subsets of electron-emitting sections of the addressable array are activated to compensate for movement of the x-ray source. By activating the different subsets of electron-emitting sections, an effective focal spot of the x-ray position appears to retain the same shape, size, and position from the perspective of the imaging target, despite movement of the x-ray source itself.

  • Patent number: 11047997
    Abstract: A radiation imaging system images a distributed source of radiation from an unknown direction by rotating a scatter mask around a central axis. The scatter mask has a pixelated outer surface of tangentially oriented, flat geometric surfaces that are spherically varying in radial dimension that corresponds to a discrete amount of attenuation. Rotation position of the scatter mask is tracked as a function of time. Radiation counts from gamma and/or neutron radiation are received from at least one radiation detector that is positioned at or near the central axis. A rotation-angle dependent detector response curve (DRC) is generated based on the received radiation counts. A reconstruction algorithm for distributed radiation source(s) and/or localized source(s) are applied based on the tracked rotation position and prior characterization of the detector response for a given scatter mask. A two-dimensional image with relative orientation and source distribution is generated from the measured DRC.
