Abstract: Radiation treatment is delivered to a patient by positioning the patient such that a radiation beam is delivered to a lesion within the patient along a beam-delivery path while securing a diagnostic imaging device about the patient such that the diagnostic imaging device does not intersect the beam-delivery path. Radiation therapy is simultaneously delivered along the beam-delivery path while diagnostic images are obtained using the imaging device.

Abstract: The invention concerns a gearbox (21) for a lift truck with telescopic jib. Such a gearbox comprises a torque converter (30) in input, and an output shift (45), characterized in that it comprises: an input shaft, called primary shaft, connected to the torque converter (30) and whereon is arranged a clutch mechanism (32); a secondary shaft (35) driven in rotation by the clutch mechanism (32); two pinions, namely first (37) and second (38) pinions, mounted freely rotatable on the secondary shaft (5) and capable of being driven alternately therewith depending on the movement of a synchronizing device; a tertiary shaft (40) coupled with the secondary shaft (45) through the first pinion (37) and a reversing pinion (42) driven by the second pinion (38), the tertiary shaft (40) comprising a plurality of pinions (39, 41, 46, 47) for coupling with the output shaft (45), in accordance with the desired transmission ratio.
