Birdcages for low and high field MRI can be delivered. Like dipole arrays, birdcages can be combined with high density receive array for high sensitivity and fast parallel imaging. Depending on frequency and imaging target a best fitting solution can be chosen.
For example, an integrated 1H/23Na transmit coil for combined imaging of anatomy and sodium metabolism. Transmit coil were integrated with multi-channel receive coil for accelerated 1H and or 23Na imaging. Current solution focuses on imaging of the knee1, but can be used for imaging of other extremities. Prototype can also be upscaled to a headcoil model.
