Recently there has been growing interests in radial fMRI. However, the reconstruction algorithm is also an important issue in K-space radial sampling. In this work, we have investigated the effect of a novel reconstruction method based on polar Fourier transform, for radially acquired fMRI data in polar coordinates. Based on its special features such as central focusing behavior, the obtained results demonstrate the capability of this method in reliable activity detection in targeted regions and also show a higher temporal stability in those areas.
