Three-dimensional coronary angiography.
For at least two decades coronary cine-angiograms have been reviewed on film projectors.  The cardiologist most often reviews the multiple two-dimensional projections of the coronary arterial tree on a screen, and then mentally create a three-dimensional (3-D) model of the patient's arteries.  The ability to synthesize this data and grasp the three-dimensionality of a patient's specific anatomy is quite difficult and requires extensive training and experience to perfect. Fortunately, with advances in computer hardware and software, cardiologists, with all levels of experience, will have assistance with this difficult task.  It is now possible, with the use of computers, to reconstruct and display a patient's coronary angiogram in 3-D, allowing the cardiologist to review this data in ways not previously available.  In the near future, enhancements in the technique will allow this technology to be placed on-line, directly in the cardiac catheterization laboratory, greatly facilitating the ability to diagnose abnormalities and more appropriately plan treatment strategies.
