| Abstract(in English) | In our previous quasi 3D inverse scattering sound velocity image reconstruction method, it was necessary to acquire the large amount of data on the 2D observation plane for different views around the object. Therefore, the realization of the present method was difficult because of the long acquisition time and the high hardware cost of array sensor. To overcome the problem, using sparse array (1.5D array) sensor, a method is presented which enable to dramatically reduce the number of the sampling points in the elevation direction without sacrificing the quantitative quality of the image. Furthermore, from the results of both simulation and experiment examination using spherical phantom object, it was verified that 3D sound velocity image of the phantom object can be successfully reconstructed with good quantitative resolution. |
