PROBLEM TO BE SOLVED: To provide a parameter processor capable of reducing the burdens of a person in charge of inspections and a patient and improving the accuracy of a parameter obtained by an inspection in an inspection of a heart valve disease.SOLUTION: The parameter processor includes: an image acquisition part for acquiring volume data including the region of a heart in a plurality of phases arranged in time series; a cross-sectional image derivation part for deriving a cross-sectional image cut down at a prescribed cross section in the volume data of each phase; a contour setting part for setting a contour of ventricular myocardium in a cross-sectional image of each phase; a change information derivation part of deriving change information showing a change in the length of the contour or in the area of a region surrounded by the contour during a prescribed period or at a prescribed time point in a cardiac cycle on the basis of the contour of each phase; and a display part for displaying the change information.SELECTED DRAWING: Figure 1 |
