Claim One:
1. A method of magnetic resonance imaging using a magnetic resonance imaging scanner which generates a magnetic field that is more linear adjacent a magnetic isocenter and is less linear displaced from the magnetic isocenter, the method comprising: obtaining a first magnetic resonance image of a patient including an anatomical target and at least one fiducial marker displaced from the anatomical target, the first image being obtained at a position of the patient within said scanner wherein the anatomical target is located in close vicinity to said magnetic isocenter and the at least one fiducial marker is located further from the magnetic isocenter than the anatomical target, such that a region of the first image which includes the anatomical target is less distorted than a region which includes the at least one fiducial marker; obtaining a second magnetic resonance image of the patient including the anatomical target and the at least one fiducial marker, the second image being obtained at a shifted position of the patient within said scanner wherein the at least one fiducial marker is located in close vicinity to said magnetic isocenter and the anatomical region is located further from the magnetic isocenter than the at least one fiducial marker such that a region of the second image which includes the at least one fiducial marker is less distorted than a region which includes the anatomical target; merging the less distorted region of the first image which includes the anatomical target and the less distorted region of the second image which includes the at least one fiducial marker into a composite image; and at least one of storing the composite image in computer memory and displaying the composite image on a monitor.
