ULTRASONIC 3-DIMENSIONAL IMAGE RECONSTRUCTION METHOD AND ULTRASONIC WAVE SYSTEM THEREOF

Disclosed are systems and methods for reconstructing a three-dimensional ultrasound image. The method may include generating a two-dimensional image having various directivities in a frequency space based on plane wave data; manipulating the generated two-dimensional image to generate three-dimensional image data; and reconstructing a three-dimensional ultrasound image by performing an inverse fast Fourier transformation on the three-dimensional image data. The method may further include using a fast Fourier transformation, a lookup table, back-projection, filtering, de-noising, compressed sensing, and/or the projection-slice theorem.
