Publication number: 20220113360Abstract: A magnetic resonance imaging (MRI) system having a resistive, solenoidal electromagnet for whole-body MRI may include ferromagnetic material within an envelope of the electromagnet. The system can be configured to have a field strength of at least 0.05 Tesla and its main electromagnetic field can be generated by layers of conductors instead of bundles. Certain electromagnet designs may be fabricated using non-metallic formers, such as fiberglass, and can be constructed to form a rigid object with the layers of conductors by fixing all together with an epoxy. The electromagnet may be configured to have two separated halves, which may be held apart by a fixation structure such as carbon fiber. The power supply for certain electromagnets herein may have current fluctuations, at frequencies of 180 Hz or above, of at least one part per ten thousand without requiring an additional current filter.Type: ApplicationFiled: December 22, 2021Publication date: April 14, 2022Applicant: ViewRay Technologies, Inc.Inventors: James F.
