Abstract:
1. A method for producing a set of diffusion weighted images of a subject positioned in a field of view (FOV) of a magnetic resonance imaging (MRI) system, the steps comprising: a) acquiring with the MRI system a set of projection views of the subject positioned in the FOV using a pulse sequence with a motion sensitizing gradient directed along a first direction the set of projection views forming an undersampled image data set; b) repeating step a) a plurality of times, wherein the motion sensitizing gradient is directed along a different direction each time and the projection views are all interleaved; c) producing a composite image with projection views from a plurality of the undersampled image data sets wherein a value at each composite image pixel indicates information about the subject positioned in the FOV; d) reconstructing a diffusion weighted image of the subject from each undersampled image data set by; e) calculating a diffusion tensor from the diffusion weighted images.
