Abstract
An ultrasonic imaging system that reduces image flashes by selectively replacing imaging parameters with corresponding imaging parameters from prior time sequences. Imaging parameters include filtered energy, unfiltered energy, variance, acceleration, velocity, and detected echo magnitude. Imaging parameters in several consecutive time sequences can be replaced with the same prior imaging parameter value until the flash is no longer detected. Spatial averaging can be used to improve detection and suppression of image flashes.
