Abstract
The present invention relates generally to MR imaging and, more particularly, to a method and apparatus for reconstructing zoom MR images. An RF coil assembly having a number of detection elements is provided. The RF coil assembly is designed such that the number of detection elements that may be used to acquire imaging data may exceed the number of data acquisition channels of the MR system. Accordingly, the detection elements may be grouped into a number of sets wherein each set transmits acquired data to a specific data acquisition channel to acquire data of a larger region-of-interest (ROI) or, alternately, only one set of detection elements corresponding to a smaller ROI may be activated wherein each detection element of the set transmits data to a data acquisition channel. As a result, a zoom image may be reconstructed.
