Abstract

Ultrasonic tomography technique has a great potential value in many applications such as medicine, underwater acoustics, non-destructive testing, etc. However, one of the most disadvantages of this technique is time consumption in reconstruction process. The distorted Born iterative method (DBIM) has been utilized to reconstruct the ultrasound tomography. It can take several iterations depend on the quantity of measured signals. This paper has proposed a solution of fast reconstruction by combining interpolation technique and DBIM. The tomography of scatters' sound contrast is first reconstructed with a raw meshed integration area. We can easily obtain the convergent even after one or two iterations using DBIM. After that, the interpolation is applied to the signal to obtain a dense image. A method like nearest neighbor is chosen because it doesn't generate any new data values. Finally, the dense image is brought back to DBIM to continue the reconstruction process. The simulation show that we can save up to 50% of reconstructed time. © 2011 IEEE.
