Abstract:
1. A method for accelerated dynamic MR imaging able to handle time-related disturbances, comprising: acquiring k-space data from an object at a first time point and a first k-space location; acquiring k-space data from the object at a second time point and a second k-space location; identifying potential movement of the object using the k-space data; separating temporal variations associated with time related disturbances from temporal variations not associated with time related disturbances; applying a first filter, in a first function space, to the k-space data not associated with the time related disturbances to obtain a first temporary dataset; applying a second filter, in a second function space, to the k-space data associated with the disturbances to obtain a second temporary dataset; and reconstructing an image of the object having reduced artifacts using the first and second temporary datasets.
