ABSTRACT:
A radiation treatment apparatus (10) including a stand (12), a gantry (14) movably supported on the stand (12), the gantry (14) having a vertical section (16) and a generally linear cantilevered strut section (18), the cantilevered strut section (18) having a supported end adjacent the vertical section (16) and a projecting end opposite the supported end, a substantially linear particle accelerator (30) disposed within and longitudinally supported in generally parallel relationship with the cantilevered strut section (18), the accelerator (30) having a predetermined injection point (32) where particles are launched in the accelerator and a predetermined exit point (34) where the particles are discharged from the accelerator, a treatment head (22) coupled to the remote end of the cantilevered strut section proximate the exit point (34), the treatment head (22) for emitting a radiation beam (27), and a tuneable stiffening apparatus (40) attached to the accelerator (30) for substantially maintaining alignment between accelerated particle beam (27) and the bending magnet (35) and target (39) supported by the strut section (18).
