Among neutron imaging techniques, computed tomography represents the most powerful fool when an accurate 2D mapping of the internal structure of an object is desired. In order to exploit the capabilities of this technique, it is necessary to develop a detection system able to acquire the required projections with an enhanced spatial resolution and sensitivity. This could be achieved by the use of novel CCD sensors, but they are not yet available in commercial cameras. Thus, a modular system for the readout of CCD sensors was constructed allowing a fast data acquisition and a simple camera that could be easily upgraded by simply replacing the active sensor has been built. The entire system was used to acquire projections for neutron computed tomography, offering good performance spatial resolution and data transfer rate. A numerical evaluation of system performance when performing NCT is given by the analysis of sample objects.
