Structural design and analysis of 7 T active-shield animal MRI magnet system

Ultra-high field(≥7 T) magnetic resonance imaging(MRI) systems are expected to provide high-resolution spectrum imaging, multi-nuclide imaging, and structural photos at scales close to neuronal and neural loop levels. Advancements in Ultra-high field MRI for human use necessitate research progress in animal MRI. This work focuses on the design and analysis of superconducting magnets and cryostat for 7 T animal superconducting magnetic resonance imaging systems. Factors considered include electromagnetic stress, safety margins, and uniformity. A detailed analysis and evaluation of the scheme's feasibility are carried out.

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
