Abstract
In FIG. 2 (A), a reception beam (102) is formed using a weighting function (112). A position of a peak of the weighting function (112) is set at the position of the reception beam (102). A reception beam (104) is formed using a weighting function (114), and a position of a peak of the weighting function (114) is set at the position of the reception beam (104). A reception beam (106) is formed using a weighting function (116) and a position of a peak of the weighting function (116) is set at a position of the reception beam (106). In this manner, the positions of the peaks of the weighting functions (112, 114, 116) are shifted in the receive aperture, to follow movements of the reception beams (102, 104, 106) caused by electrical scanning.
Claims15
An ultrasound diagnosis apparatus comprising:
- an array transducer having a plurality of transducer elements;
- a transmitting unit which outputs a transmission signal to the plurality of transducer elements;
- and
- a receiving unit which applies a reception weight on a reception signal obtained from the plurality of transducer elements in a receive aperture, based on a position of each transducer element in the receive aperture, wherein
- the receiving unit shifts a position of a peak of the reception weights in the receive aperture, to follow a movement of the reception beam.
