Abstract
Methods and apparatus for reducing the amount of computation required by nonlinear operations in medical ultrasound imaging by using lower-order polynomials to approximate the nonlinear functions. The method can be applied to envelope detection, phase detection, logarithmic compression and other nonlinear functions. Various pre-processing techniques (e.g., pre-reducing the data range and pre-dividing an entire range of the input into a number of subranges) can optionally be used prior to the polynomial approximation to achieve better accuracy, further reduce the polynomial order, and/or simplify the implementation.
