    • A method of preparing silica aero-gel powders having a short preparation time and stable preparation processes. In the method, the silica aerogel powders are generated by using a water glass solution, an inorganic acid, an organosilane compound and an organic solvent. The method includes dispersion-solution generating, gelating and solvent exchanging and drying. In the dispersion-solution generating, a dispersion solution is generated by dispersing the water glass solution and the organosilane compound in the organic solvent. In the gelating and solvent exchanging, silica hydrogel is generated by adding the inorganic acid to the dispersion solution and simultaneously performing gelating and solvent-exchanging. In the drying, the silica aerogel powders are generated by drying the silica hydro-gel.

    • 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.
