We have created models of the cardiac venous system and the coronary arteries using methods described in the Static Imaging Methodologies section. Using Mimics Software (Materialise, Leuven, Belgium) we can segment out the vasculature by highlighting the injected contrast within the scans. We have created models of the individual systems as well as models of both the arteries and veins in order to study the anatomical relation between the two. From these models, we have measured several anatomical parameters for each major vessel:

  • Arc Length
  • Tortuosity (Arc length/linear distance)
  • Branching Angle
  • Diameters
  • Distance to the Ostium

It should be noted that from such data, cardiac device designers can quantify anatomical parameters of interest: e.g., cardiac vein branching angles can be measured and used to aid in the development of delivery systems for placing pacing leads in to these veins. Descriptions of the anatomy, nomenclature, and clinical applications of the major coronary vessels can be found in the Coronary System Tutorial.
