1. the bearing calibration of functional image shift in the neural navigation is characterized in that, may further comprise the steps:

  • A, with BOLD brain function image before low field intensity MRI brain image and the art in low field intensity MRI brain image, the art before the art respectively with art before the Image registration of high field intensity MRI brain, make different field intensity, not homotactic brain image reach the unanimity on the locus;

    B, low field intensity MRI brain image in low field intensity MRI brain image and the art before the art adopted to ask for brain displacement trend based on the non-rigid body registration of characteristic point and thin plate spline method be non-rigid body translation T;

    C, non-rigid body translation T is transformed into BOLD space before the art, the line linearity of going forward side by side sampling obtains simulating the BOLD brain function image after the displacement;

    D, will simulate the displacement after BOLD brain function image and art in low field intensity MRI brain visual fusion navigate.
