Current MPI phantoms are static representations or lack clinical hard- and software evaluation capabilities. This proof-of-concept study demonstrates the design, realisation and testing of a dedicated cardiac flow phantom. The 3D printed phantom mimics flow through a left ventricular cavity (LVC) and three myocardial segments. In the accompanying fluid circuit, tap water is pumped through the LVC and thereafter partially directed to the segments using adjustable resistances. Regulation hereof mimics perfusion deficit, whereby flow sensors serve as reference standard. Seven phantom measurements were performed while varying injected activity of <jats:sup>99m<\/jats:sup>Tc-tetrofosmin (330\u2013550\u00a0MBq), cardiac output (1.5\u20133.0 L\/min) and myocardial segmental flows (50\u2013150\u00a0mL\/min). Image data from dynamic single photon emission computed tomography was analysed with clinical software. Derived time activity curves were reproducible, showing logical trends regarding selected input variables. A promising correlation was found between software computed myocardial flows and its reference (<jats:inline-formula><jats:alternatives><jats:tex-math>$$\\rho$$<\/jats:tex-math><mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                  <mml:mi>\u03c1<\/mml:mi>\n                <\/mml:math><\/jats:alternatives><\/jats:inline-formula>=\u2009\u2212\u20090.98; <jats:italic>p<\/jats:italic>\u2009=\u20090.003).
