ULTRASONIC SCANNING SYSTEM AND ULTRASOUND IMAGE ENHANCEMENT METHOD |
摘要 |
An ultrasonic measurement system comprises a processor configured for enhancing a received ultrasonic signal, where the received ultrasonic signal is a frequency domain signal. The enhancing involves deconvolving the received ultrasonic signal to yield a filtered signal, determining autoregressive extrapolation parameters based on frequency amplitude fluctuations of the filtered signal within a frequency range over which a corresponding reference signal has a high signal-to-noise ratio, and carrying out an autoregressive spectral extrapolation of the filtered signal using the autoregressive extrapolation parameters to yield an enhanced ultrasonic signal. |
