Trade off study on different envelope detectors for B-mode imaging

Autor: O.M. Sorensen, M. Schlaikjer, Jørgen Arendt Jensen, Jan Peter Bagge

Publikováno v: IEEE Symposium on Ultrasonics, 2003.

Generation of B-mode images involves envelope detection of the RF signals. Various detection algorithms are available. A trade of between performance, price, and complexity determines the choice of algorithm in an ultrasound system. A Hilbert transfo
