RESEARCH INTERESTS

Dr. Chang's research interests include instrumentation and techniques related to MR imaging guided ablation and biopsy procedures or Interventional MRI, and those related to multi-modality animal imaging platform for molecular imaging and cell tracking.

RESEARCH ACTIVITIES & ACCOMPLISHMENTS

Dr. Chang has spent major part of his career in medical imaging industry and was responsible for developing several important MRI techniques into practical upgrade products for early MRI systems of Diasonics. After Toshiba acquired Diasonics' MRI Division, he stayed on to hold managerial positions in Engineering and Quality and Regulatory departments for Toshiba, and was certified Six-Sigma Master Black Belt. Dr. Chang has authored or co-authored in six U. S. patents. He specializes in the development, engineering and introduction of medical imaging product. Since returning to Taiwan, he has successfully engineered the first MRI coil OEM products manufactured in Taiwan for export.
