Dr. George Zentai
SPIE Involvement:
Area of Expertise:
Digital x-ray imaging , Photoconductors , Amorphous semiconductors
Profile Summary

George Zentai joined Varian Medical Systems’ Ginzton Research Center (Mountain View, California) in 1998. He is a Senior Scientist and has been working as R&D Program Manager of Direct x-ray Sensor Development Projects. His team developed x-ray imagers both for medical and security applications, which went into production at Varian.
He gave many conference presentations; some of them invited ones, wrote several publications, and have many patents in the x-ray imaging field. He has also been involved in the development of low noise readout electronics, ASICs for flat panel digital imagers and special electronic testing methods. He has many years experience in photoconductor based imagers.
He has a Masters Degree in Electronics and a Ph.D. in Amorphous Semiconductors.
Previously he was Manager of Flat Panel X-ray Sensor Development at OIS (Optical Imaging Systems) and a visiting scientist at Argonne National Laboratory.
He is member of SPIE, senior member of IEEE and member of organizing and technical committees and co-chair of SPIE and IEEE conferences.
