Abstract:
1. An ultrasound apparatus configured to acquire ultrasound signals as echo signals reflected from a target, the ultrasound apparatus comprising: a transducer which acquires the echo signals reflected from the target; a storage which stores basis vectors obtained from beamforming coefficients of previously-measured echo signals; a projector configured to project the acquired echo signals on a k number of the basis vectors; a weight calculator which calculates weights to be applied to the echo signals reflected from the target, by using the projected echo signals; and a synthesizer which applies the weights to corresponding echo signals reflected from the target, and synthesizes the echo signals to which the weights are applied, wherein the k number is equal to or greater than 1 and less than a number of reception channels which receive the echo signals reflected from the target.
