Paper Abstract

This paper describes preliminary work on a real-time neutron radiography imaging system. Initially, the system provided neutron radiographs on photographic film using a gadolinium foil converter. The photos were digitized by a flat scanner. The system implements digital image processing functions for: counting and sizing, measurement, analysis, enhancement, geometric operations and scripting. After the development of these functions, experiments were done on the real-time imaging system and the functions were applied on images captured by a CCD camera. This is pioneer work related to neutron radiography in Brazil. This project is particularly original because our nuclear reactor has unique features: its core lies in a 6 m pool and the neutrons must be driven to the surface by a pipe. Another challenge of this project is the elimination of any light intensifier between the converter screen and the CCD camera. Neutron converter deficiencies have been compensated by applying digital image techniques to the neutron images. A low cost system has been achieved by exploring the benefits of digital image processing. Initial results provided by this system have encouraged us to continue the research and to enlarge its capability.
