Embodiment 1

[0032] figure 2 is a schematic diagram of a particle therapy system according to the first preferred embodiment of the present invention, the particle therapy system includes a particle accelerator 10, a particle transport device 20, a particle irradiation device 30, an irradiation control device 40, a patient positioning device, and a tumor target area 50 positioned on the patient positioning device. The particle accelerator 10 , the particle transport device 20 and the particle irradiation device 30 are respectively connected in communication with the irradiation control device 40 to control the particle beam flow. The center of the particle irradiation device 30 and the center of the tumor target area 50 are on the central axis 110a of the particle beam.

[0033] For the convenience of description, the particle beam flow can be artificially divided into the initial particle beam 110 , the first particle beam 320 , the second particle beam 340 and the third particle beam 3...

Embodiment 2

[0046] Same as Embodiment 1, the particle therapy system according to the second embodiment of the present invention includes a particle accelerator, a particle transport device, a particle irradiation device, an irradiation control device and a patient positioning device, on which the tumor target area is positioned. Such as Figure 9 As shown, the particle irradiation device includes a planarization device 360' comprising a rotating member 363' and a shutter 365'. The parts that are the same as those in Embodiment 1 will not be repeated here. The difference from Embodiment 1 is that the outer ring of the rotating member 363' is a gear structure, so as to mesh with the gear of the transmission member for transmission. In addition, according to the requirement of planarization, the shape of the shield 365' is slightly different from that of Embodiment 1.

Embodiment 3

[0048] Same as Embodiment 1, the particle therapy system according to the third embodiment of the present invention includes a particle accelerator, a particle transport device, a particle irradiation device, an irradiation control device, and a patient positioning device. The tumor target area is positioned on the patient positioning device. Such as Figure 10 As shown, the particle irradiation device includes a planarization device 360", and the planarization device 360" includes a driving member 361", a transmission member 362", a rotating member 363" and a shielding member 365". The same part as Embodiment 1 will not be repeated here. The difference from Embodiment 1 is that the transmission member 362" is a belt, so that the driving member 361" drives the rotation of the rotating member 363" by means of the belt. In addition, according to the planarization The shape of the shutter 365" is slightly different from that of Embodiment 1, but the same as that of Embodiment 2. ...

Abstract

The invention relates to a particle irradiation device, which comprises particle beams transmitted along a central axis, a collimator and a planarization unit. The particle beams are composed of a second particle beam and a third particle beam. The collimator is arranged on the transmission path of the third particle beam. The third particle beam passes through the collimator to be in the two-dimensional distribution that is strictly the same as the shape of a physical field size corresponding to a gross tumor volume. The planarization unit is arranged on the transmission path of the second particle beam and is provided with a rotatable shielding part that can rotate around the central axis. The second particle beam is planarized by the shielding part to form the third particle beam. The invention also provides a particle therapy system comprising the above particle irradiation device. Based on the planarization unit, the uniform distribution of a dosage is realized. Only by means of the simple shielding part, the desired particle irradiation device and the particle therapy system comprising the above particle irradiation device can be obtained. Therefore, the reliability of the particle irradiation device and the reliability of the particle therapy system are improved. Meanwhile, the cost is lowered.

Description

technical field [0001] The present invention relates to a device and system for treating cancer with radiation, and more particularly to a particle irradiation device and a particle therapy system including the device. Background technique [0002] Particle radiation therapy is one of the most advanced cancer treatment methods in the world. Compared with the usual photon radiation therapy (X-ray radiation therapy), when the particles are irradiated into the patient's body, the maximum dose peak will be formed at the end of the particle range, that is, the so-called Bragg peak (Bragg Peak) will be formed. Therefore, by precisely controlling the energy of the particle beam and the irradiation position of the particle beam, high-dose particles can be concentratedly irradiated into the target tumor area, and at the same time, the unfavorable irradiation dose to the normal tissues and normal organs around the target tumor can be minimized, thereby achieving Compared with X-ray r...
