Time- and frequency-domain descriptions of spatially averaged one-way diffraction for an unfocused piston transducer
(Elsevier Science, 1999-03)
Time-domain and frequency-domain expressions describing spatially averaged effects of one-way diffraction in the case of an unfocused piston transmitter and finite receiver are of theoretical and practical interest. Here, ...
Experimental point spread function of FM pulse imaging scheme
(Elsevier, 1995)
In this paper, we have examined the possibility of incorporating pulse
compression techniques into a conventional medical B-scan imaging scheme.
Linear frequency modulation fm, one form of pulse coding among many
others, ...
