Method for correcting image distortion due to gradient nonuniformity. |
| 摘要 |
<p>A method for correcting image distortion arising from magnetic field gradient nonuniformity in accordance with which the gradient nonuniformity is modeled, the expected distortion in the image calculated, and a geometric correction applied to the distorted image. In the preferred embodiment, polynomial interpolation is used to implement the geometric correction.</p> |
