In a method for reconstructing an image from an echo planar imaging sequence, the echo planar imaging sequence is used to obtain multi-line k-space data from a subject and the multi-line k-space data are divided into odd line data and even line data. Fourier transform is performed on the odd line data and on the even line data separately to obtain corresponding amplitude images. The amplitude images obtained is this manner are added to produce the final image. The method effectively eliminates N/2 artifacts by over-sampling in the phase direction. By image reconstruction being carried out separately on the odd line data and even line data of k-space data and then integrating the images, the method effectively avoids the problem of the image signal loss caused by the mutual cancellation of the odd line data and even line data.
