Abstract

We propose a new method to estimate 2-D plane of 3-D modulation transfer function (MTF) of cone-beam computed tomography (CBCT) systems using sphere phantoms. Since the 2-D plane of 3-D MTF can be calculated by taking Fourier transform of 2-D projection of the 3-D point spread function (PSF), we estimated 2-D projection of PSF by conducting the Tikhonov-Miler regularized Richardson-Lucy deconvolution (RL-TM) between 2-D projected ideal and reconstructed sphere phantoms. The 2-D plane of 3-D MTF was measured at the iso-center and off-center along the z-axis, and compared to the ideal MTF generated by computer simulation. The results show the proposed method estimates the 2-D plane of 3-D MTF reliably.
