| 1. A method for automatic optimization in spectral Doppler ultrasound imaging, the method comprising:
(a) firing at least first and second sequences of spectral Doppler pulses;
(b) determining at least first and second goal values in response to the first and second sequences, respectively;
(c) estimating a change of a spectral Doppler parameter from the first and second goal values; and
(d) automatically setting the optimal spectral Doppler parameter as a function of the estimated change;
wherein (a) comprises transmitting the first sequence in response to a first setting of the spectral Doppler parameter and
transmitting the second sequence in response to a second setting of the spectral Doppler parameter, the first setting different
than the second setting, and (d) comprises automatically setting the spectral Doppler parameter at a third setting the same
or different than one or both of the first and second settings.
