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.

RF coil assembly for use in magnetic resonance imaging

In MR imaging, the patient is placed on the table in a configuration convenient for a surgical procedure and while in the configuration the patient is moved into the field of view by moving the magnet longitudinally and the table is moved in the bore relative to the magnet so as to optimize the part to be imaged within the field of view of the magnet. After imaging the table is moved back to the preset position and removed from the magnet for the surgical procedure to commence or continue. The movement includes movement along the longitudinal axis; transverse movement side to side; rolling movement about a longitudinal axis; tilting movement about a transverse axis and bending movement of the table relative to at least one transverse hinge line in the table at a position spaced from the ends of the table.

Movable table for magnetic resonance imaging

A patient table for a common imaging system including Magnetic Resonance and X-ray retains the patient stationary in position prior to, during and subsequent to the imaging and includes a base, a patient support portion cantilevered from the base and a mattress. The RF posterior coil portions for the head and for the chest can be inserted into and removed from an operating position underneath the head and chest of the patient while patient remains supported. The chest coil is inserted from one edge in a cavity in the mattress which is reinforced by a sleeve. The signal communication cable from the chest coil is routed in front of the mattress and over the mattress so as to not to be exposed at the sides. The head coil is carried on a base plate of the patient support alongside the head support which remains in place.

Patient support table for use in magnetic resonace imaging

Radiation therapy of a lesion in a part of a patient is carried out by maintaining the patient on a patient support table in fixed position using an immobilization device while the table is rotated between a magnetic resonance imaging system, a CT imaging system for generating a 360 degree scanned image of the patient at the location of the lesion and the radiation therapy system for generating a beam of radiation for treatment of the lesion and for scanning the beam 360 degrees around the lesion. The MR image locates the lesion and the CT system is used to calculate the treatment. Registration between the MR image, the CT image and the radiation treatment is provided by the fixed position of the part of the patient on the table which is held fixed using an immobilization system suitable for the part concerned which may include a molded head mask where the head is involved.

Image guided radiation therapy

A structural support component such as a head clamp for use in imaging of a part of a patient using Magnetic Resonance and X-ray imaging is formed of different materials each of which has an Aluminum equivalence factor of less than 10 mm and generally less than 6 mm and is arranged such that the presence of the structural support component in an imaging zone of a magnetic resonance imaging system when generating the image does not generate any visually determinable distortion in the image. The materials can be epoxy resin combined with a glass fiber substrate for easily machined parts, polyphenylene sulphide with random fiber reinforcement using glass fibers for high wear parts and polyurethane foam or Polymethacrylimide foam shaped to form a required member and covered on its outer surface with a layer formed from aramid fibers for elongate parts.
