Abstract
An ultrasonic imaging system includes a 2D transducer array which transmits ultrasonic energy at an object to be imaged. The echo signals received at the separate transducer elements are weighted to produce limited diffraction beams and the weighted signals are Fourier transformed to produce a 3D k-space data array. A 3D image is produced by performing an inverse fast Fourier transform on the k-space data array.
