(A) Photo of the three-printed PMMA phantom. A branching pattern was designed consisting of parallel tubings between 313 and 1000 micron, here injected with an ink dye to illustrate inner design. (B) Maximum intensity projection (MIP) reconstruction of a 20 s cone beam scan (Siemens Zeego) of the phantom after injection of Omnipque 300. (C) Autocad design file and single shot X-ray acquisition. The size of the tubings is indicated by the following labels: 313 micron, 500 micron, and 1000 micron.

PMMA: polymethyl methacrylate.
