The present invention is generally directed to one or more devices and a method for improving quantitative coronary artery analysis. The devices which may be used with the present invention include an improved angiographic image quality phantom, an improved arterial phantom and the initial imaging of the procedure catheter. One or all of these devices may be used to increase the accuracy and quality of the arterial measurements provided by an edge detection analysis program. The method includes the initial imaging of the image quality phantom to allow for the correction of various geometric distortions present in an imaging system. Next, the tip of the procedure catheter and the arterial phantom are imaged to create an improved regression curve for the imaging system an to allow for increased accuracy in the use of the procedure catheter as a basis for the determination of the calculated artery diameters.
