    • Abstract
  • This paper re-proves the theorem for exact computing formula of lambda tomography in reference [6].The lambda tomography is a class of technology reconstructing from few scanning data,which can reduce the radiation dose of the scanned objects and improve the speed of image reconstruction.Reference [6] proved an exact reconstruction formula of lambda tomography in the case of fan beam scanning geometry.This paper provides an alternative simplified proof of the theorem in [6].
