Susceptibility mapping of a moving object

A method for magnetic resonance imaging of a moving subject, wherein the subject is moving by itself, especially a fetus, the method comprising:

• using a magnetic resonance imaging device for acquiring data from the subject, wherein the data are acquired at different positions of said subject with respect to a magnetization direction B0, utilizing a natural movement of the subject (S1);
• determining the position and/or orientation of said subject during the respective data acquisition and utilizing the natural motion of the subject to complete the missing data;
• reconstructing phase images from the acquired data (S3);
• and
• generating a susceptibility map based on the reconstructed phase images, wherein the determined positions and/or orientations of the subject are used to perform a calculation of susceptibility through multiple orientation sampling (COSMOS).

A non-transitory computer-readable medium configured store instructions readable and executable by a computer to perform a method for magnetic resonance imaging of a moving subject, the method comprising:

• using a magnetic resonance imaging device for acquiring data from the subject, wherein the data are acquired at different positions of said subject with respect to a magnetization direction B0, utilizing a natural movement of the subject;
• determining the position and/or orientation of said subject during the respective data acquisition and utilizing the natural motion of the subject to complete the missing data;
• reconstructing phase images from the acquired data;
• and
• generating a susceptibility map based on the reconstructed phase images, wherein the determined positions and/or orientations of the subject are used to perform a calculation of susceptibility through multiple orientation sampling (COSMOS).
