Computer storage and retrieval of coronary trees

Coronary cineangiography is a routine procedure for evaluation of the coronary circulation. From the biplane cineangiograms a visual representation of coronary perfusion was obtained. A collection of simple ideas and procedures to aid in the collection is described. The uses to which the tree data will be put include the evaluation of myocardial function and the formation of a library sufficiently large to enable some taxonomic classification of coronary artery patterns to be made.
