Cosmic ray muons tomography is a non‐destructive imaging technique that uses the natural radiation of cosmic ray muons to create tomographic images of objects. Here presents a novel imaging algorithm that effectively utilizes experimental measurement data to achieve rapid and clear imaging of cosmic ray muons. A clear image can be obtained with only 20 min of measurement time and approximately 200 effective muons. However, the current detection flux is only about 0.044 cm−2 min−1, which is significantly lower than the natural cosmic ray flux of about 1 cm−2 min−1.
