System and method for acquisition of a magnetic resonance image as well as device for determining a trajectory for acquisition of a magnetic resonance image

Abstract

The present invention relates to a method for acquisition of a magnetic resonance image independent on an a-priori defined field-of-view (FOV), the method comprising the sequence of steps: determining a k-space trajectory for acquisition of k-space MRI data, wherein said k-space trajectory comprises a field-of-view, FOV, independent 3D k-space trajectory, wherein the 3D k-space trajectory for acquisition of the k-space MRI data is independent of an a-priori defined field-of-view of an MRI image to be constructed, in particular wherein said field-of-view-independent 3D k-space trajectory is based on one or more Jacobi theta functions; acquiring k-space MRI data, wherein a gradient waveform corresponding to said field-of-view independent k-space trajectory is applied to magnetic field gradients of the MRI scanner; and selecting a desired field of view for the magnetic resonance image after acquiring the k-space MRI data and constructing the magnetic resonance image based on the desired field of view from the acquired k-space MRI data.
