The radiation head (7) pivots about an axis (h) on an arm (6) and trolley (5). The trolley is motor driven along circular rails (4) using a rack and pinion (4a) such that it rotates about an axis (s) which intersects with the head axis (h) and the beam axis (f). the patient is supported on a platform and headrest (2) which is very finely maneuverable along three orthogonal axis to bring any lesion to the intersection of the radiation equipment axes. |
