Extending the coverage of true volume scans by continuous movement of the subject

INTRODUCTION The spatial coverage achieved in a single MI? image acquisition is frequently constrained by hardware. The trend towards shorter magnets is increasingly limiting in this regard. Spatial coverage can be extended by obtaining multiple acquisitions with the subject repositioned between scans. This can result in discontinuities between image sets. We have explored the possibility of synthesising an extended continuous 3D data set by continuously moving the subject during the scan. The techniques described have some similarities with the SLINKY method in MOTSA angiography’
