Abstract: According to an exemplary embodiment, an ultrasound apparatus for beamforming with a plane wave transmission may comprise a transceiver connected to a transducer array having at least one transducer element, and at least one processor. The transceiver transmits at least one substantially planar ultrasonic wave into a target region at one or more angles relative to the transducer array, and receives one or more signals responsive from the transducer array. The at least one processor applies a fast Fourier transform (FFT) to the one or more signals from each of the at least one transducer element and calculates at least one frequency within a frequency region, and applies an inverse FFT to at least one produced frequency data.
