Expertise

Dr. Cheng's research lies mainly on MRI related image quality control and protocol optimization for neuroimaging. Echo Planar Imaging (EPI) and Diffusion Tensor Imaging (DTI) are the two major imaging tools in neuroimaging. There are many artifacts and various noises in EPI and DTI images. Parallel imaging technique with multi-channel coil has allowed higher spatial and temporal resolution in brain imaging but also introduced instability of noise across multiple runs of fMRI and additional noise from head motion. Dr. Cheng is interested in tackling all these problems by combining MRI physics and signal processing.

Dr. Cheng is also interested in the functional network constructed from resting state fMRI time series, and the relation between structural network and functional network.
