Document Type and Number:
WIPO Patent Application WO/2023/109064
Kind Code:
A1
Abstract:
A gradient sensitivity correction method and system. The method comprises: acquiring a three-dimensional image of a die body, wherein the three-dimensional image is collected by using an MRI device, and the die body has a known actual size on a target axis (402); performing fitting on the three-dimensional image, so as to determine a fitting size of the die body on the target axis (404); and correcting the gradient sensitivity of the MRI device on the basis of the fitting size and the actual size (406).
