1. A method to generate a magnetic resonance (MR) image of a predetermined volume segment of a living subject, comprising: in a processor, determine a respective tracking factor for each of different regions of the volume segment that allows a position of the respective region of the volume segment to be determined from the tracking factor dependent on a position of a moving area of the living subject; operating an MR data acquisition unit to acquire MR image data from the volume segment for different positions of the moving area; for each of said regions, reconstructing a magnetic resonance image thereof by calculating a position of the moving area dependent on the position of the respective region and the tracking factor for the respective region, and construct MR image data for the respective region using the MR image data of the volume segment corresponding to the calculated position of the moving area; and generating an MR image of a totality of said volume segment by combining the respective constructed MR image data of the respective regions.
