ABSTRACT
In this study a procedure for online measurement of a coronary segment length during primary stenting is presented. The spatial segmental axis is calculated from a biplane angiogram and the corresponding projection data by simple delineation of the proximal and distal segment sites in each image. In a clinical evaluation the length error, projectional foreshortening and time frame during measurement of 222 stents or carrier balloons were calculated. The overall percentage length error was 3.3(+)-2.4%. The device length imaged with a mean projectional foreshortening of 18(+)-20% was measured within 18(+)-4 s. The procedure yields the accurate length of coronary segments within a short computation time taking projectional foreshortening into account.
