Abstract
A method and apparatus are disclosed for predicting prior to injection an organ specific contrast enhancement in a patient for a preselected contrast injection protocol for pre-determining a computed tomography scan. The invention is preferably implemented in a computer program which creates a mathematical model of human cardiovascular physiology in a hypothetical patient with a specific body habitus subjected to the pre-selected contrast injection protocol. The predicted contrast enhancement is then displayed for operator approval and may be then used to control a CT scanner to perform the scan with the pre-selected injection protocol. The mathematical model includes models of organs and vessels using differential equations to describe mass transport of contrast agent through the cardiovascular system.
