Early identification of thickening of the arteries (atherosclerosis) is a vital part of aiding physicians in the prevention (or regression) of cardiovascular disease.
Stages of Atherosclerosis (plaque formation) and Cardiovascular Disease

Patients may present within normal blood pressure and lipid (cholesterol) level ranges and yet the process of vascular plaque formation (atherosclerosis) and vessel damage may have been doing damage for years
It is during the early stages of atherosclerosis and cardiovascular disease that medical interventions and life-style modification are most effective; during this period the opportunity still exists to halt and reverse cardiovascular damage.
In order to improve medical outcomes, improve the quality of life of patients and reduce the cost of treating cardiovascular disease a diagnostic technique is required that will accurately and reliably detect sub-clinical vessel damage before serious and lasting harm has been done to the vascular system and the heart.
