Sliding Phase Encoding in Table-Motion Direction for Fast Continuously Moving Table Imaging
Taniguchi Y, Takahashi T, Ochi H, Kurokawa S
Continuously moving table imaging improves extended FOV imaging speed. However, it is limited in that the directions of the phase-encoding and table-motion should not be parallel. Therefore, when homogeneous space is narrow in the table-motion direction or higher resolution is needed in the orthogonal direction of the table-motion, the read-out direction is forcibly set in an inefficient direction and the imaging time increases. To prevent this, we propose a new encoding and reconstruction that is applicable in the table-motion direction. Phantom experiments show that the proposed methods successfully reconstruct images.
