  • Publication number: 20210015439
    Abstract: Disclosed is a molecular imaging method for evaluating liver regeneration ability after ALPPS. The method includes steps of: 1) preparing a VX2 rabbit liver cancer model; 2) performing ALPPS for the VX2 rabbit liver cancer model; 3) synthesizing 18F-Fluoromethylcholine (18F-Methylcholine, 18F-FCH); 4) PET/CT imaging and data processing for 18F-FCH. The disclosure is the first to propose the use of 18F-FCH PET/CT to monitor the proliferative capacity of residual liver, and further indirectly reflect the increased ability of cell membrane synthesis on the basis that 18F-FCH has higher choline metabolism in residual liver tissue, so that the liver regeneration ability after ALPPS is evaluated by the molecular imaging method, thereby providing important new ideas for the clinical selection of ALPPS to choose the best time for second-stage surgery.

  • Publication number: 20200400746
    Abstract: A device for inspecting the rotor windings of a generator includes a sequential logic circuit that generates a full-cycle pulse. A high-voltage full-cycle pulse matching generator couples the full-cycle pulse generated by the sequential logic circuit to form a corresponding transient bidirectional rotating magnetic field pulse. The transient bidirectional rotating magnetic field pulse is transmitted to two ends and a large shaft of the generator rotor winding through an impedance-matched connecting line. The transient bidirectional rotating magnetic field pulse generates a resonance effect with each large coil in the rotor. The pulse signal coupling feedback acquisition circuit couples all waveforms reflected by the generator rotor to form a magnetic field waveform, and the magnetic field waveform is transmitted to a data acquisition system by an operational amplifier. A central processing unit transmits a digital information stream to an upper computer.
