| Abstract | ||
| The dual source computed tomography setup has been developing in the central and has potential for use as anon-invasive tool for determining the phases holdup distribution. The two sources used are Co60 (22mCi) and & Cs137 (235mCi) with energies for Cs137 equal to 0.662MeV and Co60 with two energies equal to 1.332MeV & 1.173 MeV . The object to be scanned can be exposed to both the γ-beams simultaneously. Each source is located inside Source collimator device (SCD), purpose of which is to collimate the beam to give it a fan shape. The count rate of un-attenuated photons will be measured by these detectors which will be used in image reconstruction algorithms. This DE-DSCT set-up is capable of carrying out 197 views 21 projections per view , spatially independent projection measurements during one scan of complete 360° rotation of the source around the multiphase system. Calculated results showed a substantial convergence with the real measurement values of dose rates especially in the common points. | ||
