Current Research

Traditional X-ray imaging systems have based on the absorption of material. Unlike such absorption-based X-ray imaging system, recently, the grating based Talbot-Lau interferometer employing a low brilliance and incoherent X-ray source is widely adopted in medical imaging.

 

This research focuses on a grating-based Differential Phase-Contrast (DPC) X-ray imaging microscopy system for multiphase fluid flow in three-dimensional porous media.

 

DPC CT reconstruction with limited projection views can be achieved using compressive sensing methods. The reconstructed tri-signature CT images can be further used for automatic material identification by machine learning. Our studies indicate that perfect identification can be achieved using DPC tri-signatures, which offer results superior to those provided by absorption signature alone.

 

This research focuses on trapping and controlled manipulation of sub-micron sized particles.

 

 

This research develops algorithms to optimize the shape of physical devices.
