1. A method for planning a minimally invasive direct coronary artery bypass (MIDCAB) for a patient, the method comprising: obtaining acquisition data from a medical imaging system; generating a 3D model of coronary arteries and one or more cardiac chambers of interest of the patient from said acquisition data, prior to performing said MIDCAB; identifying one or more anatomical landmarks on said 3D model and inserting corresponding translucent geometric markers thereat, utilizing user input at an operator console; saving views of said 3D model in a database; measuring sizes of lesions and a number of the lesions in the coronary arteries utilizing said 3D model; registering said saved views of said 3D model on a workstation of an interventional system, said saved views of said 3D model having said translucent geometric markers, said registering including importing said saved views of said 3D model having said translucent geometric markers to the coordinate system of said interventional system using said one or more anatomical landmarks; visualizing one or more of said registered saved views on a display screen of said interventional system; and utilizing the interventional system to quantify distance and location information for a cardiac point of interest prior performing said MIDCAB; and identifying an incision location and path for said MIDCAB based on said quantified distance and location information for said cardiac point of interest.
