Summation convolution filtered back projection and algebraic reconstruction technique for ring array ultrasound tomography based on time of flight

Abstract

Purpose of the study is to apply SCFBP and ART methods on a ring array ultrasound tomography system based on time of flight. The study was conducted with numerical and experimental object by 16 positions in circular phantom. The data set of ring array was rearranged and interpolated into parallel scheme to reconstructed by SCFBP and ART methods. The result indicated that rearrangement and interpolation is feasible to use SCFBP methods, improve speed and reconstructed image quality on ART methods.
