Review Of The Development Of A Novel Low-Dose High- Resolution Flat Panel Mammography Detector

Review Of The Development Of A Novel Low-Dose High- Resolution Flat Panel Mammography Detector – Brief Article

This (Xicon Technologies Inc.) report addresses the Field Emission X-ray Sensor (FEXIS), which is a novel flat panel combination of the X-ray photoconductor thallium bromide and a field emitter array readout. The primary objective of the research program is to develop and implement a proof-of-concept FEXIS design as a mammography sensor. The secondary objective is to investigate structural modifications leading to a viable production mammography sensor.

The FEXIS concept is analyzed in detail and a prototype design is developed. The prototype FEXIS has been built, but testing is incomplete. The field emitter panel supplier (FED Inc.) was unable to deliver panels on time, so the experimental program is behind schedule. The analytical program has been carried out to the extent possible in the absence of experimental results. The results, so far, indicate that the FEXIS mammography sensor is feasible, but that the enabling field emitter array technology is not yet well enough advanced to be applicable. However, small proof-of- concept FEXIS devices, meeting the program objectives, can be made and tested. Due to continued array delivery problems, an alternative flat panel imaging concept may be proposed that will allow all of the program objectives to be met.
