RECONSTRUCTION TECHNIQUES IN POSITRON ANNIHILATIONG. Kontrym-Sznajd W. Trzebiatowski Institute of Low Temperature and Structure Research, Polish Academy of Sciences, P.O. Box 937, 50-950 Wroclaw 2, Poland In this paper we present various reconstruction techniques applied to two-dimensional angular correlation of annihilation radiation data. We discuss the following questions: which methods is the most efficient for those data and is it true that Fourier transform methods, in contrast to the Cormack's method, need a lot of projections.
