Reducing the number of measurements required by Nyquist sampling theorem is one way to accelerate MRI acquisition at the cost of introducing aliasing artifacts. Various approaches have been proposed to eliminate aliasing artifacts, such as parallel imaging and non-Cartesian sampling. However, the higher hardware requirement of parallel imaging and complicated trajectory design and image reconstruction of non-Cartesian sampling limit their wide applications. In this abstract, we propose an MRI approach based on quadratic phase encoding, which can accelerate acquistion with efficient aliasing artifacts suppresion using a single receiver coil and uniform sampling.
