Abstract

We present a new approach for 3D reconstruction of X-ray tomographic images of a magnetic structure, called coronal loop, observed on the solar atmosphere by the Japanese satellite Yohkoh. In this approach, the intermediate cross sections images of the magnetic loop are generated with image morphing controlled by a Bezier curve in arc shape. In space science, this approach has an important application to obtain information about the solar explosions that may cause serious perturbations in terrestrial communication systems.
