Abstract
A method, a system, and an article of manufacture are disclosed for obtaining imaging data from human extremities using an Extremities MRI (EMRI) system configured to accommodate both legs of a patient during scanning by providing multiple bores, including a scanning bore and one or more non-scanning bores, deployed within an actively or passively shielded, Cryogen-Free (CF), cooled superconducting electromagnet. In various embodiments, the non-scanning bores are located between field or main coils and shield coils, and the cross sections of the bores may be circular, oval, or any other appropriate and useful geometric shape. The longitudinal axis of extra bores may or may not be parallel to the longitudinal axis of the scanning bore. In various embodiments, the EMRI system may have a passively shielded superconducting magnet in which the other leg may be placed between the outside of a cryostat of the superconducting magnet and the ferromagnetic shield components.
