Hexagonal Surface Coil for 1.5T MRI Scanner

摘要

Radio-frequency coil is the core component used in the detection of nuclear magnetic resonance signal. Usually the radio frequency coil is designed for operation on a specific magnetic field strength based magnetic resonance imaging system. This paper describe the method of implementing a hexagonal surface type receive only radio frequency coil which has ability to detect the nuclear magnetic resonance signal of ~1H nuclei at 63.87 MHz resonance frequency for 1.5T magnetic resonance imaging scanner. The RF coil in MRI is used for excitation of the magnetization and to receive the signal from the excited spins. A surface coil is usually a loop of conducting material designed specifically for localized body regions. These coils have high SNR and uniform sensitivity. The Return loss of fabricated surface coil is 24.521 dB and bandwidth is 0.188 MHz.
