# Reconstruction algorithm

In

tomography , a variety of practical**reconstruction algorithms**have been developed to implement the process of reconstruction of a 3-dimensional object from its projections. Thesealgorithms are designed largely based on themathematics of theradon transform , statistical knowledge of the data acquisition process and geometry of the data imaging system. In medical tomography, thefiltered back projection algorithm and its variants are the most efficient algorithms currently in use.**ee also***
