Algorithms and Results of Eye Tissues Differentiation Based on RF Ultrasound

Abstract: Algorithms and software were developed for analysis of B-scan ultrasonic signals acquired from commercial diagnostic ultrasound system. The algorithms process raw ultrasonic signals in backscattered spectrum domain, which is obtained using two time-frequency methods: short-time Fourier and Hilbert-Huang transformations. The signals from selected regions of eye tissues are characterized by parameters: B-scan envelope amplitude, approximated spectral slope, approximated spectral intercept, mean instantaneous fre… Show more

“…Implicit in the implanted sensor application is the requirement for the telemetry stream to negotiate the propagation properties of living tissue. A variety of modalities have been explored for transmitting energy and information through biological media, including: magnetic fields (MRI 4 and near-field powered devices 5 ), microwave 6 , ultrasound 7 8 , Infrared 9 and photonic 10 . The exacting requirements of magnetic field strength and uniformity for micro-MRI are well documented, and in general limit the method to the examination of small biological volumes that can be contained within the controlled field environment.…”

“…In addition, US can be used to obtain information on the composition of the nodular tissue by using spectral analysis of the radiofrequency signal (RF) which contains information about ultrasound-tissue interactions [16][17][18][19]. Through the identification of new coefficients [20][21][22][23][24][25][26], the spectral analysis of the RF signal is able to provide information regarding the biological structure of the tissue.…”
