Step S1 emits irradiation light towards lesions position using virtual irradiation source, and indicates incoming position；
Patient lies in the second therapeutic bed 800, is positioned by the locating slot in bed body.Virtual irradiation source is towards lesions position
Emit irradiation light, at this point, irradiation light is entered path and the non-optimal path of lesion by the incoming position on patient body.
Step S2, control device calculate best exposure pathways according to the incoming position and the lesions position；
Since the lesion of each patient is likely located at different location, such as chest, leg or head, therefore, according to lesion
The difference of position need to design optimal path, to improve therapeutic effect to greatest extent, and reduce and damage caused by patient.
Step S3, the second therapeutic bed 800 carry out the movement of six-freedom degree according to the best exposure pathways, make irradiation light
Line is directed at lesion with optimal path；
After optimal path is determined in calculating, the second therapeutic bed 800 carries out the movement of each freedom degree as needed, with
Irradiation light is set to be directed at lesion with optimal path.
Step S4, control device calculate location parameter after second therapeutic bed 800 positions；
Step S5, the first therapeutic bed 400 carry out the movement of six-freedom degree according to the location parameter.
First therapeutic bed 400 can be identical with the second therapeutic bed 800, can also be different.When the first therapeutic bed 400 with
When second therapeutic bed 800 is identical, control device calculates the location parameter after the positioning of the second therapeutic bed 800 and can control for second
The location parameter of bed 800 itself is treated, such as rotates angle, X to the moving distance with Y-direction, adjustable height；To further increase
Therapeutic efficiency, during obtaining location parameter according to virtual irradiation source and the second therapeutic bed 800, the first therapeutic bed 400 can be with
The linkage of second therapeutic bed 800, therefore, after the positioning of the second therapeutic bed 800, the first therapeutic bed 400 is also complete according to its location parameter
Therapeutic room 600 is directly entered by preparation room 700 and is treated at positioning, patient, the first therapeutic bed 400 of operation is no longer needed to, suffers from
Person is treatment time most of the time in therapeutic room 600.When the first therapeutic bed 400 and the second therapeutic bed 800 are different
When, then control device can calculate location parameter, at this time according to the structural difference of the second therapeutic bed 800 and the first therapeutic bed 400
Location parameter be position coordinates meter according to the distance and lesion of lesion relative virtual irradiation source with respect to the second therapeutic bed 800
What is obtained is converted into the parameter of the first therapeutic bed 400 movement, sick with the neutron streaming alignment for guaranteeing that final irradiation channel projects
Stove.
Further, first therapeutic bed 400 is identical as 800 structure of the second therapeutic bed.So be conducive to simplify
Control device.
In the optinal plan of the present embodiment, after step S3, further includes:
Step X, redefines incoming position, obtains optimal incident position；
Step Y makes marks in the optimal incident position.
For the precision for further increasing positioning, can first make marks to optimal incident position in preparation room 700, Huan Zhejin
Enter therapeutic room 600 treat when, can according to marker for judgment whether precise positioning.It is fixed if neutron streaming incoming position is overlapped with label
Position is precisely；If not being overlapped, need through control device accurate adjustment.
The present embodiment includes above-mentioned MNSR Reactor neutron therapy device, therefore with above-mentioned MNSR Reactor neutron therapy device
All advantages substantially increase diagnosis and treatment efficiency by cooperating above-mentioned MNSR Reactor neutron therapy device and the second therapeutic bed 800.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
