Abstract: A system for reconstructing a magnetic particle image based on a pre-trained model aims to address the influence by point spread function and reduce the computational and time costs, which results in low reconstruction accuracy, or high acquisition time and computational costs for high-precision images. The system is implemented by: generating a simulation system matrix; pre-training a pre-constructed neural network model, and fine-tuning a pre-trained neural network model by performing a downstream task; and inputting real data corresponding to the downstream task into the pre-trained neural network model after fine-tuning, thereby playing an auxiliary role to acquire a high-quality reconstructed MPI image. The system fits the relationship between different harmonics, which helps enhance frequency-domain information.

Abstract: A system for reconstructing a magnetic particle image based on adaptive optimization of regularization terms includes: a MPI device for scanning an imaging object to acquire a voltage response signal; a signal processor for constructing a system matrix; and a control processor for reconstructing the magnetic particle image based on an arbitrarily selected regularization term, inputting the reconstructed magnetic particle image to a regularization-term adaptive optimization neural network model for enhancement processing, taking the enhanced magnetic particle image as a first image, and calculating a loss value between the first image and an initial image to acquire a final reconstructed magnetic particle image. The system adopts a neural network model-based automatic learning approach, instead of the approach of manually selecting regularization terms and adjusting parameters, to improve the reconstruction efficiency and quality of the magnetic particle image.

The method includes: constructing, based on hysteresis effect and hysteresis inertial growth differences of n superparamagnetic iron oxide nanoparticles (SPIOs) under trapezoidal wave excitation, an equation set of quality of n SPIOs in a to-be-tested sample formed by any composition of n SPIO standard products; solving the equation set to obtain the quality distribution of the to-be-tested sample at position r; and performing rearrangement, color assignment, and image merging on the quality distribution to implement multi-color quantitative imaging of various particles in magnetic particle imaging (MPI). The method broadens the functions of MPI to realize multi-color quantitative imaging, such that MPI has greater potential for application in the medical field.
