Magnetic resonance system and method for correction of distortion due to continuous movement of patient table
Abstract:
In a method and magnetic resonance (MR) for reduction and correction of image distortions that occur in the generation of MR images of an examination subject that is arranged on a table that is continuously driven through the MR system during the generation of the MR images and whose cause is the acquisition of MR data of an image at varying positions within the MR system, raw MR data are acquired in multiple segments with radial filling of k-space with the raw data, an intersection region in the k-space center is determined that is covered by multiple segments given the radial filling of the raw data in k-space, and the distortions are automatically calculated based on the intersection region of at least two different segments.
