Abstract
An ultrasound system is disclosed wherein an encoded signal is emitted into a patient. A B-mode image is formed by decoding a harmonic of an echo signal and the Doppler image is formed by decoding the fundamental of the echo signal. Decoding includes convolving the echo signal with a time-reversed fundamental or harmonic of the code used to generate the encoded signal. The code may be a linear frequency modulated pulse.
