Blood vessel cross-sectional shape digitizing apparatus and blood vessel cross-sectional shape digitizing method using the same

摘要

In the present invention, the blood vessel cross-sectional shape digitizing apparatus 10 digitizes the shape of the intima 120 of the blood vessel in the cross-sectional shape of the blood vessel after the stent S is inserted into the lumen 110 of the blood vessel. The blood vessel cross-sectional shape digitizing apparatus 10 calculates a plurality of coordinates on the boundary between the intima 120 of the blood vessel and the lumen 110 in the image representing the cross-sectional shape of the blood vessel in a state where the blood cell component is not substantially present inside. Shape digitizing means for digitizing the shape of the intima 120 based on a plurality of coordinates obtained by the coordinate obtaining means to obtain. According to the present invention, a blood vessel cross-sectional shape digitizing device and a blood vessel cross-sectional shape digitizing method using the same for quantifying the shape of the blood vessel intima in the cross-sectional shape of the blood vessel after the stent is inserted into the lumen of the blood vessel Can be provided.
