[specific embodiment]
With reference to the accompanying drawings utility model is further described.
Please refer to Fig. 1 to Fig. 6.This utility model gamma ray radiotherapy unit comprises motion 1, treatment 2, the absorption plant 3 that absorbs gamma ray, the rotor 4 that can rotate, the collimator apparatus 5 that gamma ray is collimated and the shield 6 that is used to shield gamma ray.In the treatment 2 a plurality of radioactive sources are installed, collimator apparatus 5 is installed in the exit of this treatment 2 gamma ray, and described rotor 4 links to each other with described motion 1 rotation, and this a plurality of radioactive sources and to collimate body 5 suitable are used to make gamma ray to converge at a bit.In the present embodiment, described rotor 4 has two adjutages, and these two adjutages are arranged to U-shaped or C shape structure in opposite directions, and treatment 2 is installed on first adjutage, and absorption plant 3 is installed on second adjutage, and this absorption plant 3 and gamma ray is relative.A plurality of radioactive sources 21 of this utility model gamma ray radiotherapy unit become fan-shaped distribution on a circular arc; the gamma ray of these a plurality of radioactive source emissions is converged to a bit; it is focus; it also is the S point among Fig. 2; form static focus; utilize simultaneously the principle of arcing irradiation again; make the ray of static focus walk around the axis that S orders and swing arcing or rotation; finish dynamic focusing; thereby realized the quiet dynamic focusing of multi-source; the low dosage that high dose distributes and focus is outer that forms in the focus distributes, and reaches the purpose of killing lesion tissue protection normal structure.Wherein, collimator apparatus 5 comprises support member 51, drives driving device 52 and collimation body 53 that the collimation body rotates, and described is that support member 51, driving device 52 and collimation body 53 are installed on first adjutage of described rotor.For satisfying the requirement of different big small lesions, this collimation body 53 is made up of the collimator that a series of interfaces vary in size, simultaneously in order to realize the automatization of therapeutic process, described collimation body 53 adopts the projective table type structure, the some groups of collimators that diameter is different radially distribute on the surface of this projective table type collimation body 53, the collimating aperture diameter of every group of collimator is identical, the distribution in this collimating device collimation hole is corresponding with distribution of radiation, as shown in Figure 4, driving device 52 drives boss and rotates, thereby has finished the automatic conversion of collimating aperture.Shield 6 in this utility model gamma ray radiotherapy unit is a drawer-type structure, and the size of this drawer is suitable with treatment 2, and under non-therapeutic state, shield is put in treatment 2 automatically, as shown in Figure 6, and in order to guarantee operator's safety.When beginning treatment, shield 6 is opened automatically, and treatment 2 is automatically moved to treatment position under the drive of motion 1, and control system is selected collimator automatically according to the requirement of treatment planning systems, begins the treatment to the patient.
This utility model gamma ray radiotherapy unit is in treatment, the patient lies on the therapeutic bed 7, these therapeutic bed 7 transfixions, the one end is provided with head positioning framework adapter 8, and this head positioning framework adapter 8 is used for patient's head is fixed on therapeutic bed.Rotor 4 is the top to bottom, left and right, front and rear motion under the drive of motion 2, and simultaneously, rotor 4 also can rotate around motion 2 feathering axis.Because radioactive source is concentrated and is distributed on one section camber line, therefore reduced the volume of shield, alleviated the weight of shield greatly.Simultaneously when treatment patient's shielding requirements is lower than shielding requirements to operator, therefore the shielding thickness of treatment head is far smaller than the shielding thickness of shield, and the shielding weight of treatment head is further alleviated, and has therefore reduced the driving load of drive system.Adopt the above mode, can system cost be reduced greatly from many-sides such as material, structure and control system.This utility model has also also designed absorption plant on the direction relative with ray, pass the gamma ray of human body when treating to absorb, thereby reduced the shielding requirements of equipment to machine room, has reduced the cost of machine room.Treatment head and absorption plant are installed on two adjutages of rotor simultaneously, thereby this rotor forms the U-shaped structure of an opening, has opened the treatment space, have removed sense of depression and the fear of patient when treatment.
Certainly, a plurality of radioactive sources can also have other distribution form, for example be distributed on the plate body, this moment collimator collimating aperture all towards focus, gamma ray behind collimating device collimation is converged to a bit gets final product.
