| 摘要 | In some aspects, a magnetic system for use in a low-field MRI system. The magnetic system comprises at least one electromagnet configured to, when operated, generate a magnetic field to contribute to a B0 field for the low-field MRI system, and at least one permanent magnet to produce a magnetic field to contribute to the B0 field. | ||

| 主权项 | 1. A magnetic system for use in a magnetic resonance imaging system, the magnetic system comprising: at least one electromagnet configured to, when operated, generate a magnetic field to contribute to a B0 field for the magnetic resonance imaging system, the electromagnet comprising at least one electromagnetic coil wound using a copper or aluminum conductor to generate a magnetic field; and at least one ferromagnetic component configured to capture and direct at least some of the magnetic field generated by the electromagnet to increase the magnetic flux density within an imaging region of the magnetic resonance imaging system, wherein the B0 field generated is less than or equal to approximately 0.2T and greater than or equal to approximately 0.1T. | ||
