摘要
A system and method for automatically providing artifact warnings in Pulsed-Wave (PW) Doppler imaging is provided. The method includes acquiring, by an ultrasound system at a pulse repetition frequency (PRF), Pulsed-Wave (PW) Doppler signals from a selected gate position in a high PRF mode. The method includes determining, by a processor of the ultrasound system based on the PRF, a position of a virtual gate along a PW line in a B-mode image. The method includes presenting, at a display, the virtual gate at the determined position along the PW line in the B-mode image. The method includes analyzing, by the processor, B-mode image intensity values at the virtual gate in the B-mode image to determine whether the B-mode image intensity values exceed an intensity threshold. The method includes providing, by the at least one processor, a virtual gate warning when the B-mode image intensity values exceed the intensity threshold.
