Title: Innovations in Nerve Imaging by Peng Sun

Introduction

Peng Sun is an accomplished inventor based in St. Louis, MO (US). He has made significant contributions to the field of medical imaging, particularly in understanding nerve function and pathologies. His innovative work has led to the development of a unique patent that enhances the visualization of nerve conditions.

Latest Patents

Peng Sun holds a patent titled "Imaging nerve function and pathologies using diffusion basis spectrum imaging." This patent focuses on how repetitive electrical activity can produce microstructural alterations in myelinated axons. His research demonstrates that these transient microstructural changes can be non-invasively visualized through two magnetic-resonance-based approaches: diffusion fMRI and dynamic Tspectroscopy in ex vivo perfused bullfrog sciatic nerves. The non-invasive diffusion fMRI method, based on standard diffusion tensor imaging (DTI), effectively localizes sites of axonal conduction blockage, which may occur in neurotrauma or other lesion types. The diffusion fMRI response is graded in proportion to the total number of electrical impulses carried through a specific locus. Additionally, the diffusion basis spectrum imaging (DBSI) method reveals a reversible shift of tissue water into a restricted isotropic diffusion signal component, consistent with sub-myelinic vacuole formation. Peng Sun has 1 patent to his name.
