Since its inception in 1896, X-ray imaging has been significantly applied in medical diagnostics. Radiographic X-ray imaging has evolved into digital radiography from film-type analogy technology. Amorphous silicon thin-film transistor based flat panel X-ray detector was introduced a decade ago, and has become a ubiquitous platform for almost all digital radiography modalities including chest radiography, mammography, and fluoroscopy. As a core of the detector, pixel technology has thus been developed to tackle the clinical challenge of digital radiography.
In this talk, I will present an overview of two fundamental pixel architectures: passive pixel sensor and active pixel sensor, followed by my very recent work in "smart" pixel concept.
Dr. Kai Wang is an assistant professor at SYSU-CMU Joint Institute of Engineering (JIE) since December 2013. He received a B.Sc. degree in Electrical Engineering from Huazhong University of Science & Technology, Wuhan, China in 2000, and a M.A. Sc. degree in Microelectronics & Solid State Electronics from Dalian University of Technology, Dalian, China in 2003. He earned his Ph. D. degree in Electrical & Computer Engineering from the University of Waterloo, Waterloo, Ontario, Canada in 2008 and was thereafter cross-appointed as a NSERC postdoctoral research fellow by Thunder Bay Health Science Centre, where he had been conducting research on biomedical imaging until he joined Apple Inc. in Cupertino, California in August 2011. At Apple, he was involved in touch sensor development for various Apple products.
He has a broad spectrum of research interests including biomedical imaging, touch and display, biosensors, optoelectronics, and etc. He has published over 30 journal papers/conference proceedings and coauthored 8 patents. He also currently serves as an Associate Editor of IEEE/OSA Journal of Display Technology and is an active member of SPIE and SID.
