US 2022/0011387 A1 · GRADIENT COIL SYSTEM

Abstract

A gradient coil system suitable for use in an MRI system. The gradient coil system having a gradient body having a bore extending therethrough and at least one frustoconical portion arranged about the bore. A diameter of a first end of the bore is greater than a diameter of a second end of the bore. The gradient coil system also includes a gradient coil assembly arranged about the bore having at least one frustoconical section substantially conforming to the at least one frustoconical portion of the body, the gradient coil assembly generating gradient fields in a Diameter of Spherical Volume (DSV) for medical imaging.
