New Ultrasonic Imaging Findings from South China University of Technology Discussed (Barker coded excitation with linear frequency modulated carrier for ultrasonic imaging)

By a News Reporter-Staff News Editor at Health & Medicine Week -- Investigators discuss new findings in Ultrasonic Imaging. According to news reporting originating from Guangdong, People's Republic of China, by NewsRx correspondents, research stated, "A new Barker coded excitation using linear frequency modulated (LFM) carrier (called LFM-Barker) is proposed for improving ultrasound imaging quality in terms of axial resolution and signal-to-noise ratio (SNR). The LFM-Barker coded excitation has two independent parameters: one is the bandwidth of LFM carrier, and the other is the chip duration of Barker code."

Our news editors obtained a quote from the research from the South China University of Technology, "To improve the axial resolution, increase the bandwidth of LEM carrier; and to improve the SNR, increase the chip duration of Barker code. In this study, a LFM pulse with proper (

According to the news editors, the research concluded: "In addition, the LFM-Barker coded excitation is robust for frequency dependent attenuation of tissues."
