Claim Text:
1. An inner image generating apparatus, comprising: a first receiver configured to receive an inlet track information and a first passage time of a muon at a first track detector provided outside of a structure; a second receiver configured to receive an outlet track information and a second passage time of the muon at a second track detector provided outside of the structure at an opposite side of the first track detector; a displacement calculator configured to calculate a track displacement of a track of the muon passing the structure based on the inlet track information and the outlet track information of the muon; a mean energy calculator configured to calculate a mean energy of the muon based on a time-difference between the first passage time and the second passage time; a data integration circuit configured to integrate a product of the track displacement and the mean energy of the muon on a projected plane assumed inside the structure, wherein each of the product is configured to be allocated at a corresponding position of the muon passing at the projected plane; and, an image generating circuit configured to generate an inner image of the structure by identifying a position of matter at the projected plane based on an integrated product obtained at the data integration circuit.
