Abstract
An apparatus for intra-operative MRI includes a patient table with a movable magnet and an RF coil having an upper portion and a lower portion. The upper portion is formed of a foam material flexible to different shapes with a pair of stiffeners formed of connected pivotal elements extending from a central back-bone embedded in the top sheet of the foam to hold the flexible material in the different shapes and is carried at one end of a flexible foam arm attached to a side rail of the table and stiffened by a longitudinal stiffener. A head clamp is attached to the table with a C-shaped holder for the skull clamp pins. The lower coil is movable by flexing about longitudinal lines to different curvatures and is held channel shaped by the C-shaped holder. It is attached at one longitudinal end to an adjustable mount connected to the head clamp.
