Neutron stimulated emission computed tomography (NSECT) is a new approach for biological spectroscopy and imaging. Since thegamma-ray photons emitted from stimulated element have energies from 100 keV to about 6 MeV, previous reports have proposed thatthe projection path can be defined by the neutron beam. In this paper, another possible method has been applied and the performancepresented through simulations. When using signals from a single BGO crystal it is impossible to achieve g
