Abstract
Recently we published two explicit formulae for finite inverse Hilbert transforms [You, J and Zeng, GL, 2006]. This paper presents a straightforward proof of the formulae, the data requirements, and some computer simulations to verify the formulae. Examples of region-of-interest (ROI) tomography using truncated projections and the first formula of the finite inverse Hilbert transform are shown.
