Parallel-Beam CT Reconstruction Based on Mojette Transform and Compressed Sensing

Wen Hou and Cishen Zhang

Abstract—A novel frame of parallel-beam Computerized Tomography (CT) reconstruction is proposed. The CT projections are firstly converted to Mojette projections. Then 1D Fourier transform is applied to the modified Mojette projections, followed by an exact mapping of the gained Fourier coefficients to the 2D Fourier domain of the scanning object. Finally the scanning object can be reconstructed from the partial Fourier coefficients by compressed sensing (CS). Experimental results show that using this frame, the purpose of reducing the radiation dosage during CT examinations without compromising the image quality can be achieved.

Index Terms—Computerized tomography, parallel-beam, mojette transform, compressed sensing.
