摘要

•A phantom for investigation of spatio-temporal resolution of MPI scanners.•Tracer boluses of adjustable size, volume, and flow velocity can be provided in a range which is representable for medical applications.•A clear dependency of the spatial resolution on the velocity of the moving bolus was found qualitatively.
