Abstract:
A magnetic resonance imaging system uses a first RF coil for acquiring a magnetic resonance signal from a subject, and a device for estimating a cardiac phase of the subject based on the magnetic resonance signal acquired by the first RF coil. The first RF coil, for example, can be an RF coil exclusive to cardiac phase estimation. The magnetic resonance imaging system also uses a second RF coil for acquiring a magnetic resonance signal based on the estimated cardiac phase, and a device for reconstructing a magnetic resonance image of the subject based on the magnetic resonance signal acquired by the second RF coil. Thus, MRA can be performed by estimating a cardiac phase.
