Patent ID: 8419641

Claim:
A medical image display method that displays the tomographic image acquired by scanning a cross section of a heart in an object to be examined on a display unit and obtains a volume of a cardiac chamber region encompassed by an inner wall surface of a cardiac chamber and a valve ring surface based on the displayed tomographic image, comprising: a step of tracing and displaying a portion equivalent to the inner wall surface of the cardiac chamber on the tomographic image; a step of displaying a valve ring line equivalent to the valve ring surface connecting both end points of the traced cardiac chamber inner wall trace line; a step of displaying an inner cavity axis passing through the center of the valve ring line and the position in the cardiac chamber inner wall trace line which is the farthest from the center of the valve ring line; a step of displaying a plurality of partition lines which is orthogonal to the cardiac chamber axis and of which their both ends intersect with the cardiac chamber inner wall trace line; a step of calculating a cardiac chamber volume of a first cardiac chamber region formed by the plurality of partition lines using the disk method; a step of calculating a cardiac chamber volume of a second cardiac chamber region encompassed by the partition line which is the closest to the valve ring line from among the plurality of partition lines, the valve ring line and the cardiac chamber inner wall trace line; a step of calculating the entire cardiac chamber volume by the sum of the calculated volumes of the calculated first and second cardiac chamber regions; and a step of displaying the cardiac chamber volume of the first and second cardiac chamber regions and/or the volume of the entire cardiac chamber region.
