Magnetic resonance imaging having radiation compatible radiofrequency coils

摘要

Improved compatibility of MRI with radiation imaging is provided by MRI RF coils having transmissive coil sections. The transmissive coil sections are substantially transparent to the penetrating radiation employed by the radiation imaging system. Thus the transmissive coil sections can be disposed in a field of view of the radiation imaging system without introducing artifacts into the radiation images. Transparency to penetrating radiation can be achieved by substantially including only low atomic number (i.e., Z<29) elements in the transmissive coil sections. Preferably, the transmissive coil sections are fabricated substantially from aluminum.
