Abstract

Reconstruction aspects of spiral-scan magnetic resonance imaging are investigated with polar and rectangular coordinates based reconstruction. Several reconstruction algorithms based on these coordinates are tested, and reconstructed image qualities are compared with a mathematically built phantom. An improved reconstruction algorithm with dc-offset correction in projection domain is proposed, which provides the best reconstructed image quality from simulation. Image artifact with existing algorithms is also completely removed with the proposed method.
