Abstract: An X-ray backscatter imaging system for precise searching for container hazardous cargo, includes: an X-ray generator configured to irradiate X-rays toward a search target container; and a cylinder-type scattering X-ray detection collimator configured to allow only scattering X-rays generated on a specific layer of the search target container among the X-rays irradiated from the X-ray generator to pass through, and X-rays scattering on a specific layer is measured by adjusting angles of collimators based on a layer to be measured, so that a search for hazardous cargo by layer of the container can be performed precisely.
