Dr. ANDREW EINSTEIN (Cardiologist, Columbia University): Using beta-blockers or other medications to lower patient's heart rate, which in many cases will chip the radiation dose down by minimizing the number of images which are taken, and matching the technical parameters such that the patient doesn't receive too many x-rays.
