• Diffraction Tomographic Imaging With A Circular Array 

      Vasuki, A (Indian Institute of Science, 2005-06-02)
      In the conventional diffraction tomography a linear array is used to receive forward scattered field. Then a standard algorithm like back propagation or Fourier domain interpolation is used for reconstruction of the object. ...
    • Estimation Of Object Shape From Scattered Field 

      Buvaneswari, A (Indian Institute of Science, 2005-09-27)
      The scattered field from an object, when illuminated with ultrasound, is useful in the reconstruction of it's cross section - a problem broadly classified as 'tomography'. In many situations of medical imaging, we will be ...
