摘要
本文提出一种B超STC自动调节的新准则,以B超图像中最大亮度像素的灰阶及其数目为标准来控制整个图像的质量。实验证明,利用此准则研制的STC自动调节系统能使每个深度层区的回波信号获得较好的补偿。
A new criterion for B-mode ultrasonic image auto-STC is proposed in this paper. The grey scale and number of the pixels with the highest intensity in a ultrasonic image are used as the Criterion to control the quantity of ultrasonic image, The results of the experiments have proved that the auto-con-rtol system developed with this criterion can compensate very well the echo-am plitude of each area in th idcertion of propagation of ultrasound.
