<P>PROBLEM TO BE SOLVED: To provide an improved RF coil for MR having an upper RF coil of semi-rigid flexible foam in a user adjustment type, a support mechanism suitable for the coil, and a support part for a lower coil. <P>SOLUTION: An apparatus for intra-operative MRI includes a patient table 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. The upper portion is carried at one end of a flexible form arm attached to a side rail of the patient table and stiffened by a longitudinal stiffener. A head clamp is attached to the patient 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 in a channel shape by the C-shaped holder, and it is attached at one longitudinal end to an adjustable mount connected to the head clamp. <P>COPYRIGHT: (C)2012,JPO&INPIT |
