Biography

Dr Zheng is a Senior Lecturer within School of Dentistry and Medical Sciences. He has been teaching medical radiation science courses at CSU since 1998, both at undergraduate and postgraduate levels, and supervising PhD research students as principal supervisor. He published widely including two patents and a co-authored book. He received multiple research awards and grants. Dr Zheng’s current research projects includes: (1) MRI neuroimaging and Alzheimer’s disease. A CAD tool based on signal detection theory was implemented for early detection and diagnosis of Alzheimer’s disease and an imaging biomarker is currently being validated for early detection and screening of Alzheimer’s disease; (2) Quantitative X-ray Computed Tomography. A body size and tube voltage dependent factor were discovered for correcting beam hardening in X-ray CT. A patent was registered in China and a research prize was awarded by the CIOFMP, China. (3) Radiation dose and image quality optimization in X-ray MDCT, DR/CR and dental CBCT/OPG. A governing equation has been discovered for clinical X-ray CT and radiographic imaging which results in significant dose reduction to patients and personalized X-ray imaging protocols. A patent was registered in Australia and a research prize was awarded by the AART, USA.
