Phantom package for clinical use. (a) The schematic of phantom package containing a perfusion phantom comprised of three components and a static phantom comprised of six components; static phantom components contain different contrast concentrations (0~5 mM). Both phantoms were surrounded by thermal insulation material (polyurethane foam). A fiberglass cushion was placed on the top of the phantom package to provide patient comfort and to prevent heat transfer from the patient additionally. The combined thickness of the fiberglass cushion and polyurethane foam was about 50 mm.
