Latest Patents

Kok-Hwee Ng holds a patent for a "Method and apparatus for preventing axial spatial aliasing in ultrasound." This invention utilizes a progressive sampling rate technique to maintain the sampling rate at the Nyquist frequency of the I/Q data. It incorporates a tunable equalization bandpass filter in the front end of the imager, followed by an increase in the sampling rate via axial interpolation. This method effectively prevents aliasing during the nonlinear detection process. If an envelope detector is employed, the bandwidth of the detector output should be approximately double that of the I/Q data. In such cases, the sampling rate is doubled or more through axial interpolation before envelope detection. A 2-point linear interpolator can be utilized, and the axial interpolator can be automatically activated or deactivated based on the application. After detection, the signal can be low-pass filtered to restrict the speckle bandwidth prior to log compression.
