Abstract

A design method for a high-sensitivity high-temperature superconducting detection coil for magnetic particle imaging belongs to the field of magnetic particle imaging technology and solves the problem that the existing technology improves the signal-to-noise ratio of the detection coil by reducing the exogenous interference mode, and the internal noise of the coil affects the further improvement of the signal-to-noise ratio. The design method establishes a calculation model for the loss mode and loss intensity generated by each layer of the thin film of the superconducting coil under MPI conditions, and a series of high-temperature superconducting coils are made and verified based on the calculation results of numerical theory and the rigid bending conditions of the high-temperature superconducting tape; and an MPI imaging system using the high-temperature superconducting detection coil is developed to perform imaging experiments and performance verification. The high-temperature superconducting detection coil model of the present invention is set in an ideal MPI measurement environment, and is constructed taking into account the frequency, intensity, direction of the magnetic field, the number of coil turns, and the diameter. It has lower total loss of the detection coil, lower noise voltage, and better MPI imaging effect of the superconducting detection coil.
