An elongated patient support table [22] with a horizontal patient support surface has a contoured radiolucent table extension assembly [26, 126] connected thereto in cantilever fashion for supporting the head and upper torso of a patient [27]. An outer end of the extension assembly [26, 126] has a reduced width compared to the support table [22] to enable extendable movement of the radiolucent extension assembly [26, 126] into a scanning zone defined by a central opening [112] of a diagnostic unit such as a CT scanner [20]. The table extension assembly [26, 126] supports the patient [27] via an inboard radiolucent horseshoe headrest [32, 132] and an outer tool support [54, 122] for holding an outer stabilization device [66, 166] such as a radiolucent skull clamp [74, 174]. The combination of the support table [22] with the radiolucent table extension assembly [26, 126] and the inner and outer stabilization devices [32, 132, 66, 166] support the patient [27] in a desired position during successive scanning or surgical procedures. With an imaging system [24] operatively connected to the CT scanner [20], the table extension assembly [26, 126] permits a neurosurgeon to conveniently obtain updated images of the scanned region after performing a stereotactic operative procedure, thereby to immediately and easily determine if any follow-up procedures are necessary before closing up the surgical incision.

[What is claimed is:] [1.]a portable scanning machine having a toroidal shaped scanning zone and adapted to take scans in the scanning zone;an imaging system operatively connected to the scanning machine and adapted to store images representative of scans of the scanning zone taken by the scanning machine;a patient table having an upper support surface, the patient table and upper support surface including a radiolucent table extension adapted to support a head and upper torso of a patient residing in a prone position on the upper support surface, the radiolucent table extension being sized to be received within the scanning zone, the patient table and the radiolucent table extension being movable relative to the scanning machine to locate the radiolucent table extension within the scanning zone, and the radiolucent table extension including at least one of the following:an opening located inboard of an outer edge of the table extension; anda radiolucent tool support located along the edge of the table extension and holding a radiolucent head clamp adapted to securely hold the head of the patient in a fixed position relative to the table extension, thereby to assure the accuracy of scans taken of the patient by the scanning machine and subsequently stored in the imaging system.
