| Abstract: | In ultrasound tissue characterization, the backscattered RF signal is finely digitized. The signal envelope is displayed in a version thinned 1-8. Three implementations of Hilbert-transform envelope detection with thinning were timed. An array processor speeds up DFT implementation by a factor of 2.5, but convolution implementation is even faster. |
