Extrapolation of Tomographic Images Based on Data of Multiple Pulsed Probing

This paper proposes a new approach to improving image quality in pulsed X-raytomography. The method is based on establishing a functional dependence of the reconstructedimages on the duration of the probing pulses and applying an extrapolation procedure. Thenumerical experiments demonstrated that the developed algorithm effectively suppresses theinfluence of scattered radiation and significantly increases image contrast. The proposedalternative approach allows substantially increasing the stability of the method even for mediacontaining strong scattering inhomogeneities and with a significant level of noise in the projectiondata. In addition, the algorithm has greater stability to errors in the source data caused by anincrease in the duration of the probing pulses. The numerical experiments confirmed the highefficiency of the extrapolation tomography algorithm for recovering the internal structure of thetest object.
