Claim:
1. A system for analyzing blood vessel walls, the system comprising: a catheter that is advanced through blood vessels to regions of interest of blood vessel walls, the catheter comprising a catheter head housing a first energy form system that transmits a first form of energy from the head of the catheter and detects the first form of energy from the blood vessel walls and a second energy form system that transmits a second form of energy from the head of the catheter and receives the second form of energy from the blood vessel walls; a pullback and rotation system for simultaneously withdrawing the catheter head through the blood vessels and rotating the head around a longitudinal axis of the catheter; and an analyzer that determines a structural measure using the first form of energy from the first energy form system and analyzes the blood vessels walls using the detected second form of energy from the second energy form system compensated by the determined structural measure from the detected first form of energy.
