Medical Image Reconstruction Algorithm Based on The Geometric Information between Sensor Detector and ROI

摘要

In this paper, we propose a new image reconstruction algorithm considering the geometric information of acoustic sources and senor detector and review the two-step reconstruction algorithm which was previousely proposed based on the geometrical information of ROI(region of interest) considering the finite size of acoustic sensor element. In a new image reconstruction algorithm, not only mathematical analysis is very simple but also its software implemetation is very easy because we don't need to use the FFT. We verify the effectiveness of the proposd reconstruction algorithm by showing the simulation results by using Matlab k-wave toolkit.
