Latest Patents

One of Jie Tian's latest patents is a "Magnetic particle imaging reconstruction method based on neural network constrained by forward model." This innovative method utilizes a system matrix obtained through calibration, where voltage data generated by a specimen is measured. The collected data undergoes transformation into the frequency domain via Fourier transform. The frequency features are then screened using a signal-to-noise ratio threshold. A reconstruction network is built using Pytorch to map one-dimensional voltage data to a multi-dimensional magnetic particle concentration distribution. The system matrix serves as the forward model for magnetic particle imaging, allowing for the generation of simulated voltage data based on the reconstructed concentration distribution. A loss function is calculated to update network parameters, incorporating a total variation regularization term to optimize reconstruction effects.

Another notable patent is the "pH-responsive ultrasensitive fluorescent nanoprobe, preparation and using method thereof." This nanoprobe consists of pH-responsive matrix materials and fluorescent organic small molecule dyes. The preparation method involves coating dyes with matrix materials of opposite charges. This innovative approach significantly enhances the sensitivity and specificity of fluorescence imaging, enabling ultrasensitive detection of tumor microenvironment responses. The unique properties of the tumor microenvironment allow for high targeting efficacy, low background signals, and a high signal-to-noise ratio, facilitating the detection of tiny tumors.
