Abstract: A radio frequency (RF) detector array and a MRI system are provided. The detector array comprises a plurality of conductive array elements being substantially parallel to a conductive ground plane, a plurality of capacitors, wherein at least one capacitor is shunted from each array element to the ground plane to adjust a corresponding electrical length of each conductive array element, and, wherein a combination of each respective array element, at least one corresponding capacitor and the ground plane forms a resonator that resonates at a selected frequency. The detector array further a decoupling interface, and a plurality of matching boxes for matching each decoupled conductive strip to a selected impedance. A MRI system is provided including a detector array as described herein to produce MR images of the object to be imaged.

Abstract: A magnetic resonance imaging (MRI) method is described. The method includes simultaneously acquiring partial radial backprojection signals from a cylindrical array of m detectors surrounding an object, generating, in a k-space, additional backprojection signals with decimated b-fold backprojection steps. The generating includes producing 2-dimensional (2D) spatial harmonics to replace the decimated b-fold backprojection steps. The producing includes assuming that a sum of weighted sensitivity profiles of at least one of the detectors is a function of an angle between a vector k and an axis kx of the k-space and a function of a radius of a cylindrical surface formed by the array of detectors. The angle is an angle along which reconstruction of an image of the object is performed.
