A novel ultrasound imaging technique for portable and high speed imaging

In this work, a novel technique for ultrasound imaging named Computational Ultrasound has been developed. The computational ultrasound imaging operation involves sending and receiving unfocused echo pulses which are spatio-temporally apodized with random binary sequences. The single channel of acquired RF data is then decoded using convex optimization to obtain the image. The proposed system reduces or eliminates side lobes and speckle noise while providing good image quality only for a fraction of the cost and area of a conventional ultrasound system. Simulations show that computational ultrasound can successfully image sub-wavelength features at the expense of image quality.
