PROCEEDINGS OF THE XVI MEXICAN SYMPOSIUM ON MEDICAL PHYSICS.
In this paper, a modified radio frequency (RF) coil version is presented to be suitable to work at 900 MHz. The proposed coil is based on the Petal Surface Coil and Petal Resonator Surface Coil, whose resonant frequencies were 22 MHz and 64 MHz, resp
