The present invention relates to dedicated superconductor magnetic resonance imaging (MRI) RF apparatus and method of constructing the same. One Embodiment of the present invention provides an MRI breast imaging apparatus comprising an examination region, a patient support, at least one vacuum thermal isolation housing, a main magnet system, and a cryogenic system. The vacuum thermal isolation housing comprises a low vacuum space between at least one inner and an outer high vacuum enclosure. The low vacuum space hosts at least one superconductor RF coil and a heat sink assembly therein. The RF coil is in thermal contact with the heat sink assembly that is coupled to the cryogenic system through a heat pipe to achieve and maintain a desired low temperature at the superconductor RF coil. The system provides a local examination region substantially surrounded by the superconductor RF coil.

Dedicated superconductor MRI imaging system

The present invention relates to an integrated magnetic resonance imaging (MRI) RF apparatus and method of constructing the same. One Embodiment of the present invention provides an MRI apparatus comprising an examination region, a patient support, at least one vacuum thermal isolation housing, a main magnet system for generating a main magnetic field in the examination region, and a cryogenic system. The vacuum thermal isolation housing comprises a hermetically sealed high vacuum jacket that encloses a low vacuum space hosting at least one superconductor RF coil and a heat sink assembly therein. The RF coil is in thermal contact with the heat sink assembly that is coupled to the cryogenic system through a heat pipe to achieve and maintain a desired low temperature at the superconductor RF coil.
