Abstract Motion artifacts of in vivo imaging, due to rapid respiration rate and
respiration displacements of the mice while free-breathing, is a major challenge in
micro computed tomography(micro-CT). The respiratory gating is often served for
either projective images acquisition or per projection qualification, so as to
eliminate the artifacts brought by in vivo motion. In this paper, we propose a novel
respiratory gating method, which firstly divides one rotation cycle into a number
of segments, and extracts the respiratory signal from the projective image series
of current segment by the value of the epipolar consistency conditions (ECC),… More >
