X-ray backscatter imaging system for precise searching for container hazardous cargo and method for controlling the same

An X-ray backscatter imaging system for precise searching for container hazardous cargo, the system comprising:

• an X-ray generator configured to irradiate X-rays toward a search target container;
• and
• a scattering X-ray detection collimator including a rotatable cylinder, and being configured to allow only scattering X-rays generated on a specific layer of the target container among the X-rays irradiated from the X-ray generator to pass through,
• wherein the scattering X-ray detection collimator is configured to be rotatable to adjust an angle thereof to measure X-rays scattered from the specific layer of the target container, enabling precise layer-by-layer searches of the target container,
• wherein a slit that allows only scattering X-rays of a specific angle to pass therethrough is provided at a front end of the scattering X-ray detection collimator,
• wherein a first passage with one slit for allowing scattering X-rays to pass therethrough is formed in a vertical direction to a second passage with multiple slits spaced apart from each other to allow scattering X-rays to pass therethrough.
