This work presents an approach to accelerated imaging via RF and surface coil localization using a multiwindow acquisition. The sequence can be described as creating effective sensitivity profiles for each acquisition window using the in-plane RF profiles to multiply and sculpt the sensitivity profiles of multichannel receivers. Rectangular RF profiles are chosen so as to efficiently encode along the phase encode-direction, improving the ability to unwrap aliasing caused by extreme undersampling along this direction. We present both numerical studies and experimental verification of the approach.
