A neutron capture therapy system includes a neutron generator for generating a neutron beam, an irradiation room for irradiating an irradiated body and a supporting table accommodated in the irradiation room for transporting the irradiated body. The supporting table includes a supporting member for supporting the irradiated body, an adjusting device for adjusting the spatial position of the supporting member, a drive rod connected between the adjusting device and the supporting member and a first shielding member covering the adjusting device. The first shielding member prevents the adjusting device from being radiated by radiation. The adjusting device drives the drive rod to adjust the spatial position of the supporting member. The first shielding member is provided with a slot for providing a pace for the movement of the drive rod. The adjusting device is disposed in the first shielding member to greatly reduce radiation damage caused by neutrons and gamma rays to the adjusting device.一種中子捕獲治療系統，其設有產生中子束之中子產生裝置、用於向被照射體照射中子束之照射室及容納於前述照射室內之用於載置被照射體之載置台。前述載置台包括用於載置患者之載置件、用於調節載置件之空間位置之調節裝置、連接於調節裝置與載置件之間之驅動桿及包覆調節裝置之第一屏蔽件，前述第一屏蔽件避免前述調節裝置被輻射線輻射。前述調節裝置驅動驅動桿運動從而調節載置件之空間位置，前述第一屏蔽件設有給驅動桿運動提供讓位空間之通槽。調節裝置設置於第一屏蔽件內，大大降低了中子、伽馬射線對其之輻射損傷。
