Introduction

Xiufeng Li is a notable inventor based in Shoreview, MN (US), recognized for his contributions to medical imaging technology. With a total of five patents to his name, he has made significant advancements in the field of arterial spin labeling and magnetization imaging.

Latest Patents

One of his latest patents is titled "Slice ordering for MB-EPI ASL imaging." This method involves generating a perfusion weighted image using arterial spin labeling (ASL) with segmented acquisitions. The process includes dividing an anatomical area of interest into multiple slices and performing a multi-band echo planar imaging (EPI) acquisition using a magnetic resonance imaging (MRI) system. This technique allows for the acquisition of a control image dataset representative of the slices, utilizing a central-to-peripheral or peripheral-to-central slice acquisition order. An ASL preparation process is also performed to magnetically label protons in arterial blood water upstream from the anatomical area of interest. Following a post-labeling delay, the MB EPI acquisition process is executed to create a labeled image dataset, which is then used to generate a perfusion weighted image by subtracting the labeled dataset from the control dataset.

Another significant patent is "Multi-banded RF-pulse enhanced magnetization imaging." This method provides a way to determine a frequency offset against a central frequency by specifying an offset frequency for one or more RF coils. The method involves applying Gaussian RF pulses around the central frequency to a patient, enhancing the imaging process.
