Abstract
A beamforming apparatus, an ultrasound imaging apparatus, and a beamforming method are disclosed. The beamforming apparatus according to an exemplary embodiment may include a filter to select predetermined first columns, which correspond to low-frequency components, among columns that composes a transform function; and a beamforming processor to transform an input signal to another space by using a transform function composed of the predetermined selected first columns, and generate a beam signal through signal processing in the transformed space.
Claims16
A beamforming apparatus, comprising:
- a filter configured to, among components of a transform function, remove high-frequency components and select low-frequency components;
- and
- a beamforming processor configured to transform an input signal to another space by using the transform function composed of the selected low-frequency components, and generate a beam signal through signal processing in the transformed space.
An ultrasound imaging apparatus, comprising:
- a transducer configured to irradiate ultrasonic waves to a subject, receive a signal of the ultrasonic waves reflected from the subject, transform the received ultrasonic waves, and output a plurality of the ultrasonic signals;
- a beamformer configured to transform, to another space, the signal of the ultrasonic waves, which has been input through the transducer, by using a transform function, generate a beam signal through signal processing in the transformed space, among components of the transform function, remove high-frequency components, and select and process low-frequency components;
- and
- an image generator configured to generate an image by using a beam signal, which has been generated by the beamformer.
A beamforming method, comprising:
- removing high-frequency components and selecting low-frequency components among components of a transform function;
- and
- transforming an input signal to another space by using the transform function composed of the selected low-frequency components, and generating a beam signal through signal processing in the transformed space.
