Magnetic Resonance Imaging (MRI) is widely used for the diagnostic of musculoskeletal system. In the last decade, MRI scanners have shown a trend towards ultra-high field (i.e., > 7 Teslas) scanners due to higher SNR and contrast-to-noise ratio. However, UHF MRI scanners are available mainly for research, especially for brin MRI. In addition, the availability of specific radiofrequency (RF) coils geometries for different application than brain MRI is limited and of very high cost. This work describes the design, development and characterization of a volume birdcage coil for MRI of the knee at ultra-high-field MRI scanner. The results show this coil provides good homogeneity and contrast-to-noise ratio.
