摘要： MRA data is acquired from a large region of interest by translating the patient to successive stations at which successive portions of the three-dimensional MRA data set are acquired. Patient movement is chosen to track a bolus of contrast agent as it passes through the region of interest and a 3D acquisition is performed at a succession of stations. The order and shape in which k-space is sampled differs from station-to-station to achieve maximum image contrast.

摘要： To deterine glucose or other constituents of the human or animal body, near-infrared radiation containing two alternating wavelengths that have equal extinction coefficients in the tissue is directed onto a sample area of the body. The intensity relation of the two different wavelengths is adjusted so as to balance the two wavelength detected signals. The extracellular-to-intracellular fluid ratio of the tissue is changed or is allowed to change, and the alternating component of the transmitted beam power is measured. The amplitude of the alternating-current (AC) signal given by the detector represents glucose concentration or the difference from a preset reference concentration.

摘要： A method for producing multiple temporal frames of a time-resolved contrast enhanced magnetic resonance angiogram from a subject using an MR contrast agent by repeatedly applying RF pulses and sampling data in the corresponding image k-space along spiral trajectories that start at the k-space center and spiral outward toward the k-space edge.

摘要： A generation Node B (gNB) configured for Sub-Band Full Duplex (SBFD) communication in a fifth-generation new radio (5G NR) network may communicate with two or more User Equipment (UEs) during SBFD symbols. During any one or more of the SBFD symbols, a downlink transmission may be transmitted to at least one of the UEs simultaneously with reception of an uplink transmission from at least another of the UEs. The SBFD symbols may span the carrier bandwidth and may comprise at least a downlink (DL) subband and an uplink (UL) subband within the carrier bandwidth. To communicate with the two or more UE simultaneously during the SBFD symbols, the gNB may configure the UEs that are to transmit during one or more of the SBFD symbols with timing-advance offset information to be used by the UEs to adjust a configured timing-advance for initiating an uplink transmission relative to downlink symbol timing at a UE within the one or more SBFD symbols. A timing-advance offset may delay an uplink transmission of during one or more of the SBFD symbols that follows a downlink symbol. This offset or delay, relative to the timing-advance, may provide a UL-DL switching time gap when the SBFD symbol follows a DL symbol.

摘要： An imitation ceramic vase manufactured by a method which includes the following steps. (1) Applying a primer layer material on a vase made by a non-ceramic material, and letting the primer layer material to dry. (2) Applying at least one layer of first middle layer material on the primer layer material on the non-ceramic material vase. (3) Applying at least a layer of second middle layer material on the first middle layer material, and letting the second middle layer material to dry, the second middle layer material having a color which is different from that of the first middle later material. (4) Applying a surface layer material on at least one of the first middle layer material and the second middle layer material, and letting the surface layer material to dry. The surface layer material is a polyurethane imitating porcelain surface coating or an ultraviolet imitating porcelain surface coating.

摘要： For optimal image quality in susceptibility-weighted imaging and accurate quantification of susceptibility, it is necessary to isolate the local field generated by local magnetic sources (such as iron) from the background field that arises from imperfect shimming and variations in magnetic susceptibility of surrounding tissues (including air). We present a nonparametric background field removal method based on projection onto dipole fields in which the background field inside an ROI is decomposed into a field originating from dipoles outside the ROI using the projection theorem in Hilbert space.
