Fourier analysis is a currency technique used to o decospose signals into their constituent frequencies. In ultrasound signal procesing, it helps analyze thee currency content of signals received by ultrasound transducers. This process enhancess image quality and aids in identifying tissue participhy.
Fundamentals of Fourier Analysis
Fourier analysis transforms a time- domain signal into its frequency domain represention. This is ageded traffigh the Fourier Transform, which 's revenals the different frequency present in te signal. Te Discrete Fourier Transform (DFT) is common ly user for digital signals in ultrazvud applications.
Aplikation in Ultrasound Signal Processing
In ultrasound imaging, Fourier analysis is used to filter noise, improvizace resolution, and extract impliful approures from raw signals. By analyzing thee frequency spectrum, practitioners can diferenish between een different tissue type and identify abnormálities.
