Chirp ultrasound
WebApr 1, 2004 · Conventionally, chirps are used in ultrasound imaging to increase SNR when peak transmitted pressure is limited. Improvements of more than 10dB in SNR have been reported [7]. Imaging with chirped excitation signals operates by transmission of the chirp into the medium. WebSep 4, 2009 · It is important to notice that most of chirp-like signals described in the literature advocate the capability of their technique to enlarge ultrasonic system bandwidth, as the way those...
