Abstract:
1. An object imaging method by multiple acquisitions, the acquisitions consisting in passing a radiation through the object, measuring the radiation having passed through the object, the radiation being attenuated through the object from an initial radiation (Φ o ) to a total measurement radiation (Φ t object), and subtracting an estimation of a scattered radiation (Φ d object) from the total measurement radiation, the measurement radiation and scattered radiation consisting of values associated to respective parts of the object, and wherein: for at least one of said acquisitions, values of scattered radiation (Φ the scattered radiation through the object in estimated with the transposition coefficients and the scattered radiation through the imitation, the values of total measurement radiation through the objects, the values of scattered radiation through the imitation and the transposition coefficients being spread in respective tables comprising corresponding elements so that each of the transposition coefficients is associated to a respective part of the object.
