Research Conducted at University of Washington Has Updated Our Knowledge about Ultrasound Technology (Evidence for trapped surface bubbles as the cause for the twinkling artifact in ultrasound imaging)

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Ultrasound Technology have been published. According to news reporting originating in Seattle, Washington, by VerticalNews journalists, research stated, "The mechanism of the twinkling artifact (TA) that occurs during Doppler ultrasound imaging of kidney stones was investigated. The TA expresses itself in Doppler images as time-varying color."

The news reporters obtained a quote from the research from the University of Washington, "To define the TA quantitatively, beam-forming and Doppler processing were performed on raw per channel radio-frequency data collected when imaging human kidney stones in vitro. Suppression of twinkling by an ensemble of computer-generated replicas of a single radio frequency signal demonstrated that the TA arises from variability among the acoustic signals and not from electronic signal capture or processing."

According to the news reporters, the research concluded: "This variability was found to be random, and its suppression by elevated static pressure and return when the pressure was released suggest that the presence of bubbles on the stone surface is the mechanism that gives rise to the TA."
