A kind of three-dimensional therapeutic bed that is used for radiotherapy system, comprise: the therapeutic bed of pedestal, pedestal top, between pedestal and therapeutic bed, be provided with elevating mechanism, transverse moving mechanism and longitudinal moving mechanism, described transverse moving mechanism is the movable carriage that is arranged on the pedestal, described elevating mechanism is located on two trailing arms of carriage, and elevating mechanism is provided with the straight-line motion mechanism that is connected with therapeutic bed.
Straight-line motion mechanism on the described elevating mechanism is linear guide rail structure or linear bearing structure, and line slideway or linear bearing are four, is connected to the both sides of therapeutic bed.
Driving device on the described elevating mechanism is positioned at the outside of pedestal
The pedestal of radiation unit is same pedestal in described pedestal and the radiotherapy system.
The three-dimensional therapeutic bed of radiotherapy system of the present utility model, because the carriage of therapeutic bed transverse moving mechanism is arranged on the pedestal, two same moved further of trailing arm of carriage, guaranteed the displacement accuracy at transverse moving mechanism two ends, elevating mechanism is supported on the both sides of therapeutic bed by four line slideways or linear bearing, the structural rigidity that has improved elevating mechanism is strong, under the effect of therapeutic bed and patient's gravity, can not produce amount of deflection, guarantee radioactive source focus point and the accuracy that patient's lesions position on the therapeutic bed overlaps in the therapeutic process, improve radiocurable effect.
