Claim 1:
2. A system for performing magnetic resonance (MR) imaging on a subject, comprising:
an MR imaging apparatus that includes:
a magnet operable to provide a magnetic field;
an RF transmission system operable to transmit to a region within the magnetic field; and
an RF receiving system operable to receive a magnetic resonance signal from the region with the magnetic field; and

a reconstruction workstation,
wherein the reconstruction workstation is configured to cause the following method to be performed:
applying a first pulse sequence to a region of interest of the subject using the RF transmission system;
in response to applying the first pulse sequence to the object, obtaining initial k-space data D1 using the RF receiving system;
constructing a spatial factor Ux and a temporal factor Φ from the initial k-space data D1 using the reconstruction workstation;
determining a transformation T that maps the temporal factor Φ to the initial k-space data D1 using the reconstruction workstation;
applying a second pulse sequence to the object using the RF transmission system;
obtaining real-time k-space data D2 at time t using the RF receiving system;
constructing a real-time image A, where A=UxTD2, real-time image A showing the region of interest of the subject at time t using the reconstruction workstation.
