New System

Purpose: To validate ANCOR, a new system in quantitative coronary arteriography (QCA). Material and Methods: The validation procedure was performed by comparing the calibration factors of catheters filled with saline solution or contrast medium, and by measuring precision-drilled lumens in a test phantom filled with contrast medium. The results were compared with a well established and validated system, CMS. Results: The calibration test showed that the çalibration factors in the saline and contrast-medium catheters differed only a few percent when catheters with diameters of 2.0-2.67 mm were used. The phantom test showed that both systems overestimated smaller and larger diameters than these. The best results for both systems were achieved in the middle-diameter range. Conclusion: The ANCOR and CMS systems gave comparable results in catheter calibrations and phantom tests.
