1. A processing apparatus for processing cardiac image data of a living being, the processing apparatus executing a method comprising:

  • determining a plurality of fractional flow reserve values indicative of the fractional flow reserve of coronary arteries of the living being, the fractional flow reserve values corresponding to blood pressure values;

    determining a plurality of myocardial perfusion values indicative of the myocardial perfusion of portions of the myocardium of the living being;

    determining associations between the coronary arteries and the portions of the myocardium of the living being, wherein the associations define which of the portions of the myocardium are fed by which of the coronary arteries;

    determining correspondences between the blood pressure values and the myocardial perfusion values based on the blood pressure values, the myocardial perfusion values, and the associations between the coronary arteries and portions of the myocardium; and

    displaying indications indicative of the determined correspondences at one or more respective locations of the coronary arteries and/or of the portions of the myocardium.
