Abstract
An ultrasound imaging device and method are disclosed, where, multiple transmitting apertures are provided on an ultrasound probe, and an ultrasound beam is transmitted along at least one corresponding scanning line by one transmitting aperture, thereby defining multiple scanning planes. Since the multiple scanning lines in the same scanning plane intersect at an endpoint in the opposite direction of the transmitting of the ultrasound beam, and the endpoint and the area being scanned are located on both sides of the array element, the imaging range in space is larger than that of conventional sector scanning, thereby maximizing the near-field field of view.
