  • Patent number: 10765395
    Abstract: One embodiment, a medical imaging diagnosis apparatus includes a gantry, a bed and a processing circuitry. The gantry acquires data. The bed supports a table top such that the table top is horizontally and vertically movable relative to a floor surface. The processing circuitry determines a lift route of the table top from an initial height to a target height to be either a first route or a second route. The first route is in which the table top is vertically lifted relative to the floor surface from the initial height to the target height. The second route is in which the table top is vertically lifted, while being horizontally moved, relative to the floor surface from the initial height to the target height.

  • Patent number: 10770195
    Abstract: An x-ray chopper wheel assembly includes a disk chopper wheel and a source-side scatter plate that has a solid cross-sectional area that absorbs x-ray radiation and is substantially smaller than a solid cross-sectional area of the disk chopper wheel. The assembly also includes a support structure that secures the source-side scatter plate substantially parallel to the disk chopper wheel, with a source-side gap between the scatter plate and the disk chopper wheel being a distance that substantially prevents x-ray leakage. An additional, output-side scatter plate may also be provided to reduce x-ray leakage further. Embodiments enable safe operation while significantly reducing weight, which is advantageous for a variety of disk-chopper-wheel-based x-ray scanning systems, especially hand-held x-ray scanners.

  • Patent number: 10732048
    Abstract: The micromechanical photothermal spectroscopy system and method includes a cantilever assembly having at least one cantilever thermal sensor extending from a support. The sensors may be simple bimetallic sensors, or may include microchannels made from two materials having different thermal expansion coefficients for analysis of microfluids. A beam of infrared light is separated out from solar radiation by gratings and filters, and is at least partially projected on the cantilever sensor(s). Heat released from the analyte by absorbance of infrared light results in deflection of the cantilever sensor(s), which is measured by a deflection detector. A filter wheel permits tuning of the sunlight-based infrared light beam to plot a spectrum of absorbance as a function of wavelength or wave number characteristic of the analyte. The deflection detector may be optical (using a laser and position sensitive detector(s)), or may use piezo-resistive material embedded in the sensor(s).

  • Patent number: 10705229
    Abstract: An array substrate for a digital X-ray detector, a digital X-ray detector including the same, and a method for manufacturing the same are disclosed. The array substrate reduces a step difference of a PIN diode, removes a bent part from a lower part to reduce characteristic deterioration of the PIN diode, and increases the size of a formation region of the PIN diode to increase a fill factor. To this end, the array substrate allows a source region of an active layer included in a thin film transistor to be in surface contact with a lower electrode of the PIN diode, and disposes the lower electrode over a planarized source region or a base substrate, such that a step difference of the PIN diode is reduced and fill factor is improved.
