Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Fig. 1 is a kind of structural schematic diagram of radiotherapy system provided by the embodiment of the utility model, as shown in Figure 1, should
Radiotherapy system includes: the first treatment head H1 and the second treatment head H2, and the first treatment head H1 and the second treatment head H2 is issued
Beam crossover is in intersection point.Wherein, the first treatment head H1 is X knife treatment head, and the second treatment head H2 is multi-source focusing therapy head, X knife
Treatment head or conformal intensity modulated treatment head.
No matter the second treatment head H2 is what type for the treatment of head, the beam issued can be with the first treatment head H1
For the beam crossover of sending in intersection point, the dosage rate of point of intersection is the sum of the dosage rate of the first treatment head H1 and the second treatment head H2,
Compared with using single therapy head to carry out radiotherapy, the dosage rate of point of intersection can be significantly increased.In addition, due to the first treatment head
H1 is X knife treatment head, uses electron beam to practice shooting and issues X-ray, therefore without bulky shielding construction, quality is poly- compared with multi-source
The light weight of burnt treatment head, can be excessive to avoid the quality of the treatment head of radiotherapy system, guarantees that treatment head can normally revolve
Turn.
When stating radiotherapy system in use and carrying out oncotherapy, can by target spot to be treated or target area with it is above-mentioned
Intersection point is overlapped, to realize the radiotherapy of large dosage.
What needs to be explained here is that X knife treatment head is one of accelerator treatment head, in one embodiment, such as Fig. 1
Shown, X knife treatment head includes: the channel collimator and accelerator for carrying out limit beam to beam, wherein channel collimator can be with
The X beam that accelerator is issued limits Shu Weidan arrow beam, and illustratively, the diameter of the list arrow beam is about 6-60mm, certainly
The diameter of single arrow beam can also be set according to specific needs, the utility model embodiment does not limit this specifically
It is fixed.
In another embodiment, as shown in Fig. 2, X knife treatment head includes: accelerator, for carrying out limit beam to beam
Channel collimator and the multi-diaphragm collimator (Multi-Leaf between above-mentioned accelerator and above-mentioned channel collimator
Collimator, MLC), channel collimator carries out limit beam to X beam of the MLC after conformal, that is to say, that MLC carries out X beam
Large range of conformal, i.e., primary conformal, channel collimator does further beam shape to X beam, i.e., secondary conformal, thus by conformal
X beam afterwards limits Shu Weidan arrow beam.
Further, channel collimator can be detachably connected with MLC, can also be mobile relative to MLC, as shown in Fig. 2,
Channel collimator can be moved along 101 directions with respect to MLC.When channel collimator is moved to from the S2 of position from position S1, first
Treatment head H1 is conformal to the progress of X beam by MLC, and the first treatment head H1 at this moment is similar to common conformal intensity modulated treatment head,
Conformal intensity-modulated radiotherapy may be implemented；When channel collimator is moved to from the S1 of position from position S2, the first treatment head H1's
X beam of the MLC after conformal is limited Shu Weidan arrow beam by channel collimator.The first treatment head H1 can be adjusted as needed not as a result,
With the radiotherapy of mode.
Further, as shown in figure 3, the channel collimator in above-described embodiment may include: the multiple of different pore size
Radiation channel also may include: shape and/or adjustable single radiation channel.More specifically, the shape of radiation channel
It can be adjusted, for example, hexagon shown in Fig. 4 B can be adjusted to by the shape of radiation channel is rectangular as shown in Fig. 4 A；
The size of radiation channel can also be adjusted, for example, can change standard by adjusting collimation block in Fig. 4 A or Fig. 4 B
The size of straight channel, naturally it is also possible to while the shapes and sizes of collimating channel are adjusted, it is not specifically limited here.
In the case where the first treatment head H1 and the second treatment head H2 are X knife treatment head, in one embodiment, such as Fig. 5
Shown, the X beam issued respectively carries out limit beam to X beam through respective channel collimator, forms single arrow beam, such as this is single narrow
The diameter of beam is the beam crossover of 6-10mm or so, the first treatment head H1 and the second treatment head H2 sending in point of intersection.One X
The X beam that knife treatment head issues can achieve 1400MU/Min, and dosage rate is about 3.5Gy/Min, then the dosage rate of point of intersection
It can achieve 7Gy/Min, greatly improve the dosage rate of point of intersection, meet clinical high dose rate requirement.
There is also the need to explanation, multiple beams can be focused on above-mentioned point of intersection by above-mentioned multi-source focusing therapy head,
Multiple beam is X beam or gamma ray beam.When multi-source focusing therapy hair goes out gamma ray beam, as shown in fig. 6, multi-source focusing is controlled
Treating head includes: multiple Co-60 radioactive sources, and the gamma ray beam collimator (Fig. 6 is not shown) that multiple Co-60 radioactive sources issue focuses on
Intersection point.When multi-source focusing therapy hair goes out X beam, which includes: accelerator, and the X that accelerator issues is penetrated
Beam collimator focuses on intersection point.
Since the beam that multi-source focusing therapy head and X knife treatment head issue is approximate circle in point of intersection, multi-source is poly-
Burnt treatment head and X knife treatment head can cooperate and be filled formula radiotherapy to target area.The filled type radiotherapy can be with
High-dose irradiation is carried out to tumor tissues, and the radiation injury that perienchyma is subject to is smaller, accurately treats characteristic for cranium
Interior tumour or the lesser tumour of incidence have good therapeutic effect.
By taking the multi-source focusing therapy head for issuing gamma ray beam as an example, dosage rate can achieve 3Gy/Min, and X knife treats hair
X beam out can achieve 1400MU/Min, and dosage rate is about 3.5Gy/Min, in multi-source focusing therapy head and X knife treatment head
When being filled the radiotherapy of formula, as shown in fig. 6, the beam crossover of two treatment heads, in intersection point, the dosage rate of point of intersection is
The sum of two treatment head dosage rates, can achieve 6.5Gy/Min, greatly improve the dosage rate of point of intersection, meet clinic
High dose rate requirement also achieves the accurate filling treatment to target area.
There is also the need to explanation, above-mentioned conformal intensity modulated treatment head includes that conformal MLC, the beam can be carried out to beam
For X beam or gamma ray beam.Can be formed using MLC may pass through region with the consistent beam of tumor shape, and beam shines across the region
