Embodiment Construction

[0024] refer to figure 1 , the magnetic resonance scanner 10 includes a main magnet 12 that generates static (B 0 ) magnetic field, set the subject 16 ( figure 1 shown by the dotted line). The illustrated magnetic resonance scanner 10 is a horizontal cavity scanner, shown in cross-section to expose selected components for illustration. The magnetic resonance scanner 10 is a high field scanner in which the main magnet 12 generates a static (B 0 ) magnetic field, in some embodiments, the magnetic field strength is greater than or about 5 Tesla. In some embodiments, main magnet 12 generates a static (B 0 )magnetic field. Higher magnetic field strengths are also expected.

[0025] The magnetic resonance scanner 10 also includes magnetic field gradient coils 18, which at static (B 0 ) magnetic field to perform various tasks such as spatially restricting magnetic resonance excitation, spatially encoding magnetic resonance frequency and / or phase, spoiling magnetic resonance, a...

Abstract

A magnetic resonance coil includes parallel elongate conductive elements (32) arranged to define a cylinder, and end rings (34, 35) disposed at opposite ends of the parallel elongate conductive elements and oriented transverse to the parallel elongate conductive elements. The end rings are configured to support a sinusoidal 1H or other first species magnetic resonance at a magnetic field strength. The end rings and the parallel elongate conductive elements are configured to cooperatively support a second species birdcage magnetic resonance at the same magnetic field strength, the second species being different from 1H or other first species.

Description

technical field [0001] The invention relates to the field of magnetic resonance. The invention has illustrative applications in magnetic resonance imaging and spectroscopy and will be described with particular reference thereto. However, the invention will also be applicable to other magnetic resonance and radio frequency applications. Background technique [0002] Multinuclear magnetic resonance imaging and spectroscopy hold promise for a variety of applications, such as metabolic monitoring, diagnostics, and clinical monitoring. In some multi-core applications, the 1 H magnetic resonance frequency and at such as 13 C. 31 P or 23 Magnetic resonance excitation, magnetic resonance reception, or both are performed at the magnetic resonance frequency of the second species of Na. [0003] in order to 1 Both the H magnetic resonance frequency and the second species magnetic resonance frequency can be operated simultaneously or in parallel, and two separate differently tune...
