Abstract
This present application describes a multiple ultrasound beams transmitting and receiving method, comprising: transmitting a first fat beam along a first transmit line with a first transmit aperture; receiving echo of the first fat beam with a first receive aperture and forming data of a first group of receive lines; transmitting a second fat beam along a second transmit line with a second transmit aperture; receiving echo of the second fat beam with a second receive aperture and forming data of a second group of receive lines; constructing a full receive aperture by combining the first receive aperture and the second receive aperture, the full receive aperture centered in the area covering the first group of receive lines and the second group of receive lines; weighting a data of a receive line of the first group and a data of a receive line of the second group collinear with said receive of the first group respectively, and summing two weighted data.
