| Abstract: | A three-dimensional(3-D) phantom for the density distribution of the plasmasphere is established .The imaging processes of the extreme ultraviolet(EUV) Imager are computer-simulated,in which the Earth shelter is treated as a main problem.A modified ART method is devised to resolve the incomplete data reconstruction problem to validate and evaluate the proposed methods.The cone-beam EUV data are simulated based on the 3-D phantom from both a circular and semi-circular trajectories.Quantitative reconstruction... |
| Keywords: | computed tomography (CT) plasmasphere extreme ultraviolet (EUV) ART algorithm |
