Performance of sine-transform reconstruction algorithm

In this research, the performance of the Sine-Transform reconstruction algorithm was analyzed and compared with the existing reconstruction algorithms using Fourier Transform techniques. The parameters considered in the study were the time-of-flight resolution, the finite intrinsic detector resolution and the resolution of data array. Standard images such as uniform distribution, annular distribution and others were used in the theoretical analysis for comparison purposes. The statistical model for time-of-flight uncertainty published in [1] was modified to include the effect of finite intrinsic detector resolution. Preliminary results indicated the performance of this Sine-Transform reconstruction algorithm is comparable to that of the existing Fourier Transform based reconstruction algorithms. Reconstruction examples using computer simulated TOFPET data provided visual inspection of the quality of images reconstructed by Sine-Transform algorithm
