In one example, a method for acquiring a medical image includes activating a body radiofrequency (RF) coil in a body coil receive mode to obtain body calibration information of a subject. The method further includes, while the body RF coil is in the body coil receive mode, activating a surface RF coil in a surface coil receive mode to obtain surface calibration information of the subject, and correcting a reconstructed image with an intensity correction filter determined from the body calibration information and surface calibration information.

Systems and methods for an interleaved RF coil acquisition scheme

A radio frequency (RF) body coil includes a first end ring, a second end ring, a plurality of rungs connected between the first and second end rings, at least one shim holder coupled to the first end ring, and a RF shim configured to be at least partially inserted within the shim holder, the RF shim being repositionable within the shim holder to vary an operational frequency of the RF body coil. A magnetic resonance imaging system and a method of tuning the RF body coil are also described.

Radio frequncy (RF) body coil and method for tuning an RF body coil for magnetic resonance imaging

A radio frequency (RF) birdcage coil includes a first distributed capacitance end ring, a second distributed capacitance end ring, and a plurality of rungs connected between the first and second end rings, wherein at least one of the first and second distributed capacitance end rings includes a substrate having a first side and a second side, a first plurality of conductors formed on the first side, a second plurality of conductors formed on the second side, and an insulating material deposited on the first side such that the insulating material substantially covers the first plurality of conductors.
