PurposeGeometric errors in images, known as image distortion, are among the main problems in magnetic resonance imaging, including 3D imaging, measuring blood flow velocity, functional imaging and treatment planning in radiation therapy. The geometric distortion in MRI images is due to the non-uniformity of the magnetic field and nonlinearity of gradients. In the current study, the accuracy and the reproducibility of the images were respectively evaluated by phantom measuring and repeating the… Expand
