MRI of tissues with very
short T2s below 1 ms, such as bone, lung, or myelin is usually performed with 3D
radial sequences with ultra-short or even zero TE. However, with these techniques
also signals from hardware parts are detected, in particular from the RF coils.
Especially the ZTE method is highly sensitive also to materials with extremely
short T2 of tens of us. In this work, it is demonstrated how the undesired signal
is avoided during coil design and production, presenting for the first time a birdcage
coil which is virtually free of proton signal.
