1. A medical information processing apparatus comprising:
processing circuitry configured to:
obtain image data rendering a blood vessel of a patient,
generate blood vessel model based on shape of the blood vessel of the patient,
perform a fluid analysis on the blood vessel model, and calculate a fractional flow reserve “FFR” value in the blood vessel with respect to each of a plurality of positions in the blood vessel model,
select a representative position from the plurality of positions in the blood vessel model, and
cause a display to display a representative value which represents the FFR value corresponding to the representative position along with a blood vessel image indicating the blood vessel of the patient, wherein
the processing circuitry is configured to
cause the display to display a color image in which blood vessels are represented in colors corresponding to the FFR value,
determine, based on information about a pressure wire and information about the blood vessel, a first region in the vessel in which the pressure wire is configured to measure the pressure and a second region in the vessel in which the pressure wire is unable to measure the pressure, and
change a display mode of the FFR value between the first region and the second region.
