WebEx Record (the audio quality of the first 2 minutes is not good, but the rest is perfect)


CZT is currently the only semiconductor material that is capable of room temperature operation for X-ray and γ-ray radiation detector application. In this talk we will review basic principles of medical imaging modality that is called single photon emission computer tomography (SPECT). We will discuss operation of CZT detectors and associated signal processing. We will describe various integrated circuits that are used for signal amplification, filtering, multiplexing, ADC conversion and event registration. The talk will conclude with examples of SPECT equipment currently used in the marketplace. The material presented is an abbreviated version of a short course to be offered at IEEE ISCAS-2008 conference.

Biography of Dr. Krzysztof (Kris) Iniewski


Dr. Krzysztof (Kris) Iniewski is managing the R&D chip development activities at Redlen Technologies Inc., a start-up company in British Columbia. His research interests are in VLSI circuits for medical imaging. He is an editor of  “VLSI Circuits for Bio-Medical Applications”, Artech House, 2008.

From 2004 to 2006 he was an Associate Professor at the ECE department of University of Alberta where he conducted research on low power wireless circuits and systems. During his tenure in Edmonton he put together a book for CRC Press “Wireless Technologies: Circuits, Systems and Devices”.

From 1995 to 2003, he was with PMC-Sierra and held various R&D technical and management positions. Together with Carl McCrosky and Dan Minoli he wrote “Network Infrastructure and Architecture”, Wiley, 2007. Prior to joining PMC-Sierra, from 1990 to 1994 he was an Assistant Professor at the University of Toronto’s ECE department researching high-speed semiconductor devices and circuits.

Dr. Iniewski has published over 100 research papers in international journals and conferences. He holds 18 international patents granted in USA, Canada, France, Germany, and Japan. He is a frequently invited speaker and has consulted for multiple organizations internationally. He received his Ph.D. degree in electronics (honors) from the Warsaw University of Technology (Warsaw, Poland) in 1988.
