“…To estimate effective atomic numbers, data obtained from the High-Energy layer and Low-Energy layer of the detectors are subjected to some image pre-processing in many studies. [18][19][20] Then, Z ef f predictions of the objects are made by utilizing the previously obtained characteristic Z ef f -Ratio equation of each system. [14][15][16] As previously mentioned, the Z ef f -R equation varies based on the topology of each system.…”

Public places, such as airports, factories, public institutions, and organizations, require advanced security measures. X-Ray systems are often used to check passengers' luggage. Researchers and technologists are constantly working to improve the baggage-checking process by implementing various methods. This study introduces a new method for estimating the effective atomic number. Traditionally, effective atomic number estimation relies on the ratio between high-energy and low-energy images. However, the 3D Effective Atomic Number Estimation model uses high-energy and low-energy image values directly, resolving many issues of the 1D-Ratio model.
