Ultrasound is a pressure wave with frequency beyond20 ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ . Wideband ultrasound isrnultrasound pulse with mega range of frequency components. Most of the currently availablernultrasound transducers are narrow banded and fail to provide better axially resolved imagesrnfor tissues with multiple layers. The methodology used in this thesis models multi-layeredrnbiological medium based on linear acoustics of pulse-echo detection principle, normalrnincidence, longitudinal ultrasonic propagation and investigates the feasibility to detectrnperiodicity. Ultrasound propagation data was generated synthetically and subjected torncepstral analysis to detect periodicity in a multilayered skin tissue model. Rectangular pulsesrnwith a center frequency of 16-30 MHz and pulse duration of 1.2 Ã— 10âˆ’7s and 0.8 Ã— 10âˆ’7s werernapplied to a 4-layered medium. The output is measured and cepstral analysis was applied torndetermine the feasibility of periodicity detection. For layers separated by equal thicknesses,rnthe cepstral peaks existed at equal intervals where as in the case of different layerrnthicknesses, peaks existed at integer multiple of the thinnest layer thickness. In cepstralrnanalysis, when the cepstral peaks exist at equal intervals or integer multiples of the shortestrntime of flight (time of flight to the thinnest layer), periodicity detection is guaranteed. It isrnconcluded that periodicity is detected with wideband ultrasound pulses and the minimumrnand maximum bandwidth are determined based on the duration of the pulse. The possiblernlimitations with the thesis are the assumption of normal incidence planar waveforms, linearrnultrasound propagation, and parallel surfaces.
