A head fixation assembly includes a head fixation frame, a plurality of upper head fixation members, a plurality of lower head fixation members, and at least one drive mechanism. The head fixation frame includes a pair of upwardly extending spaced-apart arms defining a free space therebetween. At least one upper head fixation member extends from each of the respective arms of the head fixation frame, with each upper head fixation member adjustable relative to the head fixation frame and adapted to engage a patient's head within the free space of the head fixation frame. The lower head fixation members extend from the head fixation frame between the pair of arms, with each member adjustable relative to the head fixation frame and adapted to engage an underside of the patient's head within the free space of the head fixation frame. The at least one drive mechanism is in communication with the lower head fixation members, and is externally accessible so as to allow a user to be able to directly or indirectly advance and/or retract the lower head fixation members while the patient's head resides in the free space of the head fixation frame.

Head fixation assemblies for medical procedures

An MRI-guided interventional system includes a head support apparatus for engaging and securing the head of a patient, and a targeting frame configured to be secured to the body of a patient. The targeting frame includes a cooperating targeting cannula that is configured to guide placement of an interventional device through a burr hole in a patient's skull in vivo. The system includes an MRI-compatible camera positioned proximate to the head support apparatus, and an MRI-compatible imaging device having one end attached to the targeting frame to provide a local field of view of the burr hole, and an opposite end in communication with the camera. The system also includes a display output module coupled to the camera for receiving electrical signals therefrom and for displaying images corresponding thereto.

Imaging device for MRI-guided medical interventional systems

A head support assembly includes a base configured to be removably secured to an MRI scanner gantry, a head support frame attached to the base, and a longitudinally extending head coil apparatus adjustably secured to the head support frame. The head support frame includes a pair of elongated arms that extend outwardly in adjacent, spaced-apart, substantially co-planar relationship to form an area for receiving the head of a patient. Each arm includes a respective free end, and a head engagement rod is adjustably associated with each respective arm free end. The head engagement rods are configured to engage a patients head within the head support frame. One or more additional head engagement rods may extend outwardly from the head support frame between the pair of arms.

An articulating handle for an item of cookware is provided. The articulating handle is configured for connection with the cookware through a hinge assembly. The handle may be locked into substantially horizontal position such as for use of the cookware, or a substantially vertical position for storage. As such, cookware including such a handle can be stacked in a space-saving manner. A method for stacking cookware and a stack of cookware incorporating such a handle are also provided.

An MRI imaging coil assembly includes a primary external MRI imaging coil and a secondary external MRI imaging coil positioned proximate to the primary MRI imaging coil. The primary imaging coil has a plurality of spaced-apart RF coils and is configured to surround at least a portion of a patient. The secondary imaging coil has at least one RF coil and cooperates with the primary imaging coil to provide MRI signals to an MRI scanner. The secondary imaging coil can be movably positioned relative to the primary imaging coil. The secondary imaging coil can be movably secured to the primary imaging coil or to a patient support surface.

Trays for positioning of an object within an imaging coil for imaging procedures. Tray embodiments include a body having sides, ends, an object-supporting wall between the sides and at least one protrusion extending laterally outward from each side of the body. The protrusions cooperate with the structure of the particular imaging coil to locate the tray at a proper imaging position within the imaging coil. Patient-immobilization devices and object-holding devices may be associated with the trays. The trays enable off-the-shelf imaging coils to be adapted for use with an expanded number of patient-immobilization devices and object-holding devices.
