抄録

Methods are studied for reconstructing the radiation intensity distribution of plasma from its projection in a direction tangential to torus. The adaptation of spline function model to the image in poloidal plane gives a good result by determining knots adequately in number and location with the Akaike information criterion assisted by spatial derivative estimation. A nonlinear optimization is adopted for the guarantee of nonnegative intensity estimate. The method, which is also applicable to the tomography with cross-sectional projections, is compared with the ART and MEM in analyzing numerically generated projections and X-ray imaging data of tokamak.
