Targeted acquisition using holistic ordering (tacho) approach for high signal to noise imaging

Abstract

An MRI includes imaging coils. The MRI includes receiving coils. The MRI includes a controller in communication with the imaging coils and the receiving coils which controls the imaging coils and the receiving coils to sample k space associated with a patient in a pattern based on prior knowledge of k space data, and which reconstructs an image of the patient from the sampled k space. A method of an MRI includes the steps of acquiring preliminary k space data of a patient indicating the extent of k space data for all receiver channels using imaging and receiving coils. There is the step of determining with a controller which regions of signal associated with the k space are to be targeted by multiple acquisition blades of data with the imaging and receiver coils based on the preliminary k space. There is the step of sampling each of the regions determined by the controller with the blades to obtain k space data. There is the step of storing the k space data in a memory. There is the step of interpolating the k space data to fit in a regular rectangular grid and fitting each separate blade of k space data to the grid with the controller. There is the step of averaging overlapping k space data with the controller. There is the step of reconstructing an image from the k space data. A computer program.
