Continuously tagged imaging (CTI) expands the
application range of tagged imaging from cardiac
research to non-repeatable motion such as motility. By
sampling every tag pattern just once before refreshing,
the registered information of tagline displacement in
the temporal direction changes from the Lagrangian to
the Eulerian perspective. This study shows how,
analogous to conventional triggered tagged imaging,
complementary measures can be extracted from tagline
variation in spatial and temporal direction. The two
measures were demonstrated in a simulated CTI
acquisition in a numerical Shepp-Logan phantom and
applied to bowel motion during free breathing in one
healthy volunteer.
