Plaque diagnosis is important to prevent cerebrovascular disease in advance. Ultrasonic image is useful for plaque diagnosis because IMT (Intimal-Media Thickness) which is estimated from the thickness of inner membrane of vessels is one of the important values for plaque evaluation. However the image quality of inner membrane is not enough to estimate IMT. We have investigated a Motion-compensated Frame-accumulation Method (MFM) which is based on accumulating multiple subsequent frames acquired from the US scanner. By applying MFM to B-mode image of carotid arteries, inner membrane could be clearly imaged and IMT could be easily estimated. Additionally, we optimized several parameters of MFM for real time performance using MAP processor. The highest frame rate using single MAP processor was estimated to be 24 per second.
