Abstract: An MPI reconstruction method, device, and system based on a RecNet model include obtaining a one-dimensional (1D) MPI signal on which imaging reconstruction is to be performed, taking the 1D MPI signal as an input signal, and inputting the input signal and a velocity signal of an FFP corresponding to the input signal into a trained magnetic particle reconstruction model RecNet for image reconstruction to obtain a two-dimensional (2D) MPI image, where the magnetic particle reconstruction model RecNet is constructed based on a domain conversion network and an improved UNet network. The MPI reconstruction method, device, and system obtain a high-quality and clear magnetic particle distribution image without obtaining the system matrix.

Abstract: A second near-infrared window/first near-infrared window dual-mode fluorescence tomography system having a lighting module, an excitation module, a second near-infrared window collection module, a first near-infrared window collection module, a CT imaging module and a central control module. The central control module is configured to reconstruct second near-infrared window three-dimensional and tomographic images and first near-infrared window three-dimensional and tomographic images based on the white light images, the second near-infrared window fluorescent images, the first near-infrared window fluorescent images, and the CT images. The reconstructed three-dimensional space tumor signal has depth characteristics, which is closer to the real distribution of tumors, such that the reconstruction position is more accurate. The three-dimensional shape of the tumor is displayed intuitively and clearly at any angle with the usage of image display unit.
