Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.It should be noted that in the absence of conflict, the implementation in the utility model
Feature in example and embodiment can be combined with each other.It is below with reference to the accompanying drawings and in conjunction with the embodiments practical new this is described in detail
Type.
Referring to Fig. 1, a kind of radiotherapy apparatus 1 of guided by magnetic resonance is shown, is set comprising radiotherapy apparatus (not shown), magnetic resonance
Standby and sick bed system, magnetic resonance equipment include magnetic pole 2, magnet rotating support 11, magnetic pole support 12 and control system, work
When, under the control system, magnetic pole 2 and magnetic pole support 12 are pivoted on magnet rotating support 11.
Radiotherapy apparatus 1 has Patients Treated by Radiotherapy channel 13, and patient is located at progress NMR imaging radiotherapy in the channel；Sick bed system
7, hospital bed guide track system 8 are supported including bed board 6, hospital bed, hospital bed guide track system 8 is fixed on ground, and hospital bed support 7 can be led along hospital bed
Rail system 8 is slided, and is slidably connected between bed board 6 and hospital bed support 7；Patient 5 lies on bed board 6, is brought by sliding by bed board 6
It is treated in Patients Treated by Radiotherapy channel 13.
In order to avoid the component radiations such as the magnetron of radiotherapy apparatus, accelerating tube, electron gun, motor go out wide band electromagnetic wave,
Magnetic resonance imaging is influenced, which is equipped with the shielding dress of the radiotherapy apparatus of a guided by magnetic resonance provided by the utility model
It sets, which includes the first screened room 4 and secondary shielding room 9, and secondary shielding room 9 is socketed in Patients Treated by Radiotherapy channel 13, with the
The connection of one screened room 4 forms the space of a closure, and sick bed system is just located in the first screened room 4, and wherein hospital bed guide track system 8 is solid
Due to 4 ground of the first screened room, the first screened room 4 is equipped with Patient Entrance.
In this way in use, Patient Entrance of the patient through the first screened room 4 is lain on bed board 6 into the first screened room 4,
It is pushed into secondary shielding room 9 by sliding with bed board 6, in this way, whole process patient space is all under shielding protection,
The interference electromagnetic wave that radiotherapy apparatus and magnetic resonance imaging area peripheral edge can be shielded makes the interference journey in magnetic resonance imaging region
Degree meets requirement, guarantees image quality, to accurately implement chemotherapy.
Further, since in Patients During Radiotherapy, magnetic pole 2 understands pivoting, therefore secondary shielding room 9 and the first screened room 4
Between also there are two types of connection type.
One, secondary shielding room 9 is fixedly connected with the first screened room 4, as shown in Figure 1, connection type can be using directly weldering
It connects, the modes such as bolt is fixed.
Since secondary shielding room 9 is fixedly connected with the first screened room 4, then secondary shielding room 9 and the first screened room 4 keep same
The motion state of step, generally, due to ill bed system is accommodated in the first screened room 4, inconvenience is moved, therefore remains static, that
When work, secondary shielding room 9 is also at static shape body, does not rotate with the magnetic pole of rotation 2, i.e., Patients Treated by Radiotherapy channel 13 is in radiotherapy
It is not rotate, preferably treatment experience can be given in this way with the nervous psychology of reduction of patient.
Two, secondary shielding room 9 and the first screened room 4 are rotatablely connected, as shown in Figure 2.
Rotation connection mode can use contactless cyclic annular cut-off waveguide；Can also use conducting brush, as carbon brush,
Metal clips etc..
When secondary shielding room 9 can be rotatablely connected with the first screened room 4, then, secondary shielding room 9 can be with magnetic pole 2 one
When playing rotation, i.e. radiotherapy, Patients Treated by Radiotherapy channel 13 is rotated with mag-net synchronous, can play better shield effectiveness.
Above two connection type improves shield effectiveness to reduce shielding gap, can be in 9 He of secondary shielding room
Wire mesh is arranged in the junction 3 of first screened room 4.
For the ease of observing Patients Treated by Radiotherapy situation, end of the secondary shielding room 9 far from the first screened room 4 can be equipped with observation
Window, observation window are generally transparent.It further, can be in order to reinforce the light luminance and gas permeability in secondary shielding room 9
Lighting device and ventilation device etc. are set in secondary shielding room 9.
Observation window, ventilation waveguide window etc. has also can be set in same first screened room 4.
First screened room 4 and secondary shielding room 9 can be fabricated by general shielding material, it is preferable that due to the first screen
Cover room 4 for shielding sick bed system, volume is larger, generally selects the high metal material of conductivity and is fabricated, it is preferable that be by
Conductivity > 25S/cm metal material is fabricated, to reach preferable shield effectiveness；It is further preferred that selection copper,
The metal materials such as aluminium are prepared；And secondary shielding room 9 is due to small volume, and is located in Patients Treated by Radiotherapy channel 13, it can be with
Flexible conducting material is selected to be prepared, such as conductive fabric, conductive plastics etc..
To sum up, patient is in by the screening arrangement of the radiotherapy apparatus provided in this embodiment for guided by magnetic resonance always
In shielding space, the interference electromagnetic wave of radiotherapy apparatus and magnetic resonance imaging area peripheral edge can be shielded, magnetic resonance imaging area is made
Annoyance level in domain meets requirement.Without in radiotherapy apparatus magnetron, electron gun, accelerating tube, solid-state modulator,
The interference sources such as motor are shielded, equipment installation simply easy to process.
Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art
Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
