FRAME FOR STEREOTACTIC RADIOSURGERY USING SKELETAL FIXATION

摘要

2146252 9408704 PCTABS00032 A body-support frame (200) comprising a horizontal table (20) having two adjustable braces (50) that can be moved along the main axis of the table for straddling a patient lying within the frame. Each brace (50) is equipped with a swivelled clamp (76) attached to an adjustable system of bracket-arms (74) for the skeletal fixation and immobilization of the patient craniad and caudad to the area of interest. The frame contains orthogonal scales (26, 28 and 30) for orthogonal localization and measurements of the area of interest with reference to a chosen set of coordinates within the table. The frame also contains three adjustable radiographic calibration targets (154) that are used for selectively setting a plane of reference in the proximity of the area of interest, so that the plane may be used for lining up the frame with radiographic imaging and radiation treatment apparatus.
