A new simultaneous whole-body PET/CT imaging geometry based on the OpenPET imaging structure has been
proposed. In this geometry, multiple x-ray sources are adopted to implement the same field of view at the exactly same
time for the simultaneous PET and CT imaging process. In this paper, we conducted further quantitative analysis to the
new geometry by computer simulation. Then we examined and compared the iterative and analytical algorithms in terms
of image quality, regarding the features of the geometry. Results indicated better images were acquired with the iterative
algorithms under this geometry for the whole-body range rather than the analytical method. Improved reconstruction
images were still expected with generalization of modified algorithm for the proposed geometry. Technical
implementation of the geometry in clinical application should also be further considered.
