Developing Cold Cathode Flat Panel X-Ray Source Module for Portal X-Ray Imaging System

Portable X-ray imaging system has important application in emergency rescue, mobile healthcare and field non-destructive testing, etc. Compared to single-focus X-ray sources, flat panel X-ray sources (FPXS) allow for a more compact imaging system due to small source-to-object distance. In this study, X-ray source module is fabricated by integrating cold cathode flat panel X-ray source, collimator and electrical driver. The effect of collimator on imaging resolution was studied. This study verified the feasibility of compact FPXS module for realizing portable and lightweight X-ray imaging system.
