In a method and a computer for generating a physiologically-derived map correlated with anatomical image data spatially resolved physiologically-derived values within a value range are provided to a computer, as are anatomical image data. A frequency of occurrence of the provided physiologically-derived values is determined in the computer, depending on the occurrence of physiologically-derived values within the value range. A portion of the value range is selected in or via the computer, based on the determined frequency of the provided physiologically-derived values. Color coding is assigned in the computer to the physiologically-derived values of the value range outside the selected portion. A physiologically-derived map is generated by the computer by assigning a physiologically-derived value corresponding to the assigned color coding to its spatially resolved position in relation to the anatomical image data, and the map is shown at a display screen of the computer.
