Abstract
A method for calibrating a medical device is provided. The medical device may include a magnetic resonance (MR) device. The method may include switching a gradient field in at least one gradient direction of the MR device; obtaining a magnetic flux variation in the at least one gradient direction in at least one portion of a spatial region within a gradient field domain of the MR device using a magnetic flux measurement component; determining a center of the gradient field domain of the MR device based on the magnetic flux variation; and performing a mechanical adjustment on the MR device to locate the center of the gradient field domain at a target position based on the center of the gradient field domain, or adjusting an image reconstruction process to correct or eliminate an impact of inaccuracy of the center of the gradient field domain on a reconstructed image.
