Rotational flatness improvement
First Claim
1. An apparatus comprising:
- a first body having a vertical section and a generally linear cantilevered strut section;
a second body disposed within and longitudinally supported in generally parallel relationship with said cantilevered strut section; and
a tuneable stiffening apparatus comprising a mounting plate attached to said second body and said strut section for enabling adjustment of the stiffness therebetween;
wherein said stiffening apparatus further comprises at least one stiffener bar attached to said mounting plate, said stiffener bar providing said mounting plate with additional bending stiffness.

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).
