Investigation of gain optimization technique in Doppler ultrasound system

[摘要] References(18)Cited-By(1)In this paper the author describes a high sensitivity Doppler ultrasound system based on the principle of ensemble mean processing utilizing automatic gain optimization through system parameters. This technique allows a reduction of the physical size of the hardware and simplifies gain adjustment by reducing the gain range substantially. Such a system is not subject to Doppler ultrasound system artifacts such as the mirror effect and quantization.
