Neutron-, gamma- and X-ray three-dimensional computed tomography at the Budapest research reactor site

A new complex, neutron-, gammaand X-ray three-dimensional computer tomography system suitable for experimental and industrial applications has been built at the 10-MW Budapest research reactor site. After the system was installed, a number of objects were investigated and tomographic projections were made. The evaluation relied on two reconstruction approaches. One of these is the classical, filtered back-projection method using 180 projected pictures, while the other is based on discrete tomography optimization algorithms where fewer projections were needed. r 2005 Elsevier B.V.
