Description

<p>The Cormack inversion is a well-known procedure for tomography. However, the Fourier-Bessel function expansion could be preferably used for plasma tomography, since plasma images obtained with the Cormack inversion tend to produce a false plasma image in the boundary without regards to its advantage: the direct structural analysis of plasma is possible using a set of line-integrated data. Here we propose an application of function modification technique to revive the advantage of the Cormack inversion and present successful experimental result in a tomography system of a cylindrical plasma.</p>
