1. A method for inspecting a container for contraband, said method comprising:
scanning the container using computed tomography (CT) to identify a location of an item of interest;
determining a nuclear resonance fluorescence (NRF) scan configuration based on the location of the item of interest;
positioning the container in the NRF scan configuration;
irradiating the item of interest with high-energy photons;
detecting gamma rays emitted from the item of interest to generate signals representative of the detected gamma rays; and
analyzing the generated signals to determine a presence of contraband.
