| contents | A petal resonator volume coil for MR neuroimaging R. Rojas F. A. Barrios S. S. Hidalgo A. O. Rodríguez Física, Astronomía y Matemáticas coil resonator uniformity sensitivity MR neuroimaging A variant of the petal resonator (PERES) coil was developed for magnetic resonance neuroimaging applications. It is formed by eight2 cm-radius petal coils around a central circular-shaped coil with a total radius of 10 cm. As dictated by the theory proposed by Mansfieldin 1988, the small coil centers were separated by three times the petal coil radius to avoid mutual inductance between them. The presentconfiguration can easily accommodate a head shape and can be placed nearer the subject to be imaged than other volume coils. Enhancementfactor maps were computed to study the coil design performance based on the PERES coil foundations. Coil uniformity was theoreticallyinvestigated using the quasi-static approach for various petal coil radii. An 8-petal band coil was built, and in vivo and in vitro experimentswere conducted on a clinical MR imager together with standard imaging sequences. Brain images of a healthy volunteer are reported to showthe utility of the coil. 2006 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57065112 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
