Written by a leading ultrasound educator and designed to suit typical university, college or professional courses. Also appropriate for self-guided study. The first edition of this book sold over 5000 copies. WebbThe pulsed wave Doppler (PW Doppler) sends short pulses of ultrasound and analyzes reflected sound waves between the pulses. This is accomplished by using the same piezoelectric crystals to send and analyze sound waves. The crystals alternate rapidly between sending and analyzing ultrasound. Therefore, emitted sound waves can be …
