Abstract
The feasibility of Data Sharing PROPELLER MR imaging with multiple b-values is first proposed and evaluated in this thesis. This technique aims to shorten the amount of time when acquiring PROPELLER diffusion weighted images. Preliminary result of this thesis demonstrated that it is possible to combine each under-sampled rotating blades encoded with respect to different b-values together to create high resolution images. The combination process is accompanied with some unwanted artifacts due to data discrepancies between central and outer k-space. However, the reason and the possible strategies to reduce its effects are also proposed. The proposed methodology is able to quantitatively measure the signal behavior of bi-exponential decays.
