Abstract

In the 1980s and early 1990s, ultrasonic plaque characterization was highly subjective. When the examination was performed in a dimly lit room, the gain was usually reduced by the operator; when it was performed in a brightly lit room, the gain was increased. Although the human eye could adjust to the image brightness to a certain extent, reproducible measurements of echodensity when the same patient was scanned in another room and on different equipment were not possible. Ultrasonic image normalization which has been introduced in the late 1990s has enabled us to overcome this problem.
