Abstract
The utility model provides a medical electronic cyclotron which comprises an electronic cyclotron body, a fixed machine base 4, a rotary machine frame 3, a rotary vacuum seal device 13, a deflection magnet 14, a treatment head, and a controlled system 16. The electronic cyclotron body is arranged inside the fixed machine base 4. After an electron beam is elicited from the cyclotron, the electron beam enters a vacuum path 2 of the electron beam inside the rotary machine frame 3 via the rotary vacuum seal device 13 and is elicited from the treatment head via the deflection of the deflection magnet 14 for treatment. The fixed machine base 4 is connected with the rotary machine frame 3 to form a whole body. The rotary machine frame 3 can rotate around a rotary shaft line 18 towards a horizontal direction. The medical electronic cyclotron of the utility model can be used for replacing a medical electron linear accelerator, thus being wide used.
Description
The utility model relates to radiotherapy equipment, especially relates to the medical electric cyclotron.
The medical electric cyclotron can be used for conventional X line or electronics line radiotherapy, can also only export the electronics line, is used for art radiotherapy.Compare medical electron linear accelerator, its advantage is that the electron beam energy spread is little, and the pack performance is good, and cost is low.As shown in Figure 1, existing medical electric cyclotron is the pattern that adopts therapeutic community, microtron body 20 is installed in the independent accelerator room 21, by switching magnet and transmission line electron beam is transferred in two or more therapeutic rooms 22 and uses, form a therapeutic community.Like this, just need set up special accelerator room and therapeutic room, be unfavorable for the extensive use of medical electric cyclotron in hospital.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of microtron body integrated with the treatment head mounting rack, the medical electric cyclotron that can directly use in therapeutic room.
To achieve these goals, the utility model has adopted following technical scheme: a kind of medical electric cyclotron comprises a microtron body, fixedly support, rotary frame, rotation vacuum sealing device, deflecting magnet, treatment head and control system.The microtron body is installed in fixedly in the support, after electron beam is drawn from accelerator, enters electron beam vacuum passage in the rotary frame through the rotation vacuum sealing device, through the deflection of deflecting magnet, is drawn by the treatment head again, is used for the treatment of.Fixedly support and rotary frame are connected into one, and rotary frame can be around the rotation rotation of horizontal direction.
The utility model has the advantages that, because microtron body and treatment head mounting rack are connected into one, need not build independent accelerator room, can directly in therapeutic room, use, thereby alternative existing medical electron linear accelerator, promoted applying of medical electric cyclotron greatly.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the general arrangement of existing medical electric cyclotron;
Fig. 2 is the structural representation of an embodiment of the utility model medical electric cyclotron;
Fig. 3 is the partial cutaway schematic along the I-I line of medical electric cyclotron shown in Figure 1.
With reference to Fig. 2, Fig. 3 as can be known, in an embodiment of the present utility model, the medical electric cyclotron comprises a microtron body, fixedly support 4, rotary frame 3, Wilson seal 13, three 90 ° of deflecting magnets 14, treatment head and control system 16.The microtron body comprises modulator, magnetron 5, microwave transmission system 6, resonant cavity and injecting mechanism 7, electromagnet and vacuum chamber 8, derivation mechanism, vacuum system and constant temperature system, wherein, other elements except that modulator all are installed in fixedly in the support 4, and modulator can be placed on the control room together with control system 16.Magnetron 5 adopts EEV5125, and the energy range of microtron is 5-25MeV, and magnet diameter is 1200mm, and magnetic field intensity is 1798Gauss.Power is coupled to resonant cavity 7 by magnetron 5 outputs through microwave transmission system 6.Produce in the injecting mechanism of electron beam in resonant cavity 7, in vacuum chamber 8,, draw by derivation mechanism through the acceleration of circling round.Drawing of electron beam is to adopt rotating magnetic screen pipe 9, cooperates the scheme of deflecting magnet 17.Under the control of magnetic screen pipe 9 axle 10 in magnetic, can in 80 ° of angles, move, so that obtain the electron beam of different-energy.The actuating force of axle 10 is provided by the coil current of magnetic outer shroud 11 in the magnetic, and axle 10 is separated by the vacuum chamber wall with magnetic outer shroud 11 in the magnetic.The electron beam of being drawn by magnetic screen pipe 9 is through the deflection of deflecting magnet 17, enters electron beam vacuum passage 2 in the rotary frame by Wilson seal 13 along continuous straight runs, through the deflection of three 90 ° of deflecting magnets 14, enters the treatment head again.In the treatment head collimater 1 is housed, can draws electron beam and be used for the treatment of.In the treatment head target that can produce X ray can also be housed, draw X ray and be used for the treatment of to reach.Fixedly support 4 is connected into one by some cover bearings 12 with rotary frame 3, under the driving of the stepping motor 15 in being installed on fixed frame 4, rotary frame 3 can be around rotation 18 rotations, rotation 18 is a horizontal direction, and is vertically intersected on the K point with the axis 19 of the ray of drawing from treatment head.Target spot is placed the K point, can carry out SRT patient.This device also can be used for art radiotherapy.
