摘要：
A phantom for image quality assessment of digital breast tomosynthesis apparatus includes at least one set of beads arranged as a first ramp and as a second ramp in respective proximate parallel vertical planes in a reverse staircase pattern along a vertical direction with a final bead of the first ramp and an initial bead of the second ramp being located at substantially the same intermediate height within the phantom. The beads and additional test objects may be positioned in non-overlapping locations within the phantom to facilitate determination of multiple image quality parameters with a single scanning sequence of the phantom.
