Abstract:
1. An apparatus for ultrasound harmonic imaging, comprising: a signal transmitting unit, transmitting a transmitting signal to a reflective body, wherein the transmitting signal comprises a linearly or non-linearly frequency modulated up-sweep signal and a linearly or non-linearly frequency modulated down-sweep signal that are being transmitted simultaneously, wherein a signal receiving unit, receiving an inter-modulation component of the up-sweep and the down-sweep signal reflected by the reflective body, and receiving a second harmonic component of the up-sweep signal or a second harmonic component of the down-sweep signal reflected by the reflective body; and an image processing unit, connected to the signal receiving unit, and performing ultrasound harmonic imaging according to the inter-modulation component generated through coupling of the up-sweep and the down-sweep signal and the second harmonic component of the up-sweep signal or the second harmonic component of the down-sweep signal, so as to generate an ultrasound harmonic image.
