Development of triple-tunable radio frequency coil using geometrical overlap configuration of birdcage coil
Source abstract
Abstract
The magnetic resonance imaging (MRI) allows for acquisition of high-resolution anatomical and functional information about the subject. Moreover, metabolic information can be acquired from non-proton nuclei, such as sodium, phosphorus, and carbon. The radio frequency (RF) coil is a key component of determining signal-to-noise ratio and MR image uniformity. In addition, the RF coil is optimized for a single MRI system to maximize MR image quality. Therefore, the single RF coil cannot be used in various MRI systems with different main magnetic field strength. In this study, we propose a triple-tunable (TT) RF coil based on a birdcage coil (BC) design, which can generate a uniform RF transmit magnetic field across different MRI system’s magnetic field strengths. The TTBC is a single structure that combines a low-pass filter BC with two bandpass filter BC. The single-channel TTBC was modeled using electromagnetic simulations, and phantom MR images were acquired with 3, 7, and 11.74 T MRI systems using a manufactured single-channel TTBC.
