Abstract
Ultrasonic imaging apparatus and method are described for reducing the flash artifact in ultrasonic harmonic images. Harmonic signals are separated by pulse inversion separation which uses multiple transmit pulses which may be subject to motion artifacts. The motion artifacts are detected and subtracted from the harmonic signals to produce harmonic images with reduced flash artifacts. The motion artifacts may also be reduced by notch filtering. In another embodiment the amount of motion in the image is detected and the flash artifact is reduced in accordance with the detected motion. The amount of artifact signal which is removed is variable in accordance with anticipated image motion or clinical application.
