Abstract

The invention provides an accurate stereotactic radiosurgery treatment device which belongs to the field of a medical device. The accurate stereotactic radiosurgery treatment device is composed of a radiation device system, a six-dimensional robot treatment bed 1 and a treatment planning system. The radiation device system is composed of a frame 12 and a C-shaped machine arm 5. The frame 12 is provided with a rotating shaft 10. The rotating shaft 10 is connected with a guiderail 9 and controls rotation of the guiderail 9. The C-shaped machine arm 5 is mounted on the guiderail 9 and performs arc-shaped motion along the guiderail 9. One end of the C-shaped machine arm 5 is provided with a radiation source 2. The bottom end of the radiation source 2 is provided with a small machine head 3. The bottom end of the small machine head 3 is provided with a collimator. The other end of the C-shaped machine arm 5 is provided with a telescopic electronic portal imaging device 7 and a movable shielding protecting counterweight 8. A target organ positioning and detecting device 6 is mounted at the side part or the lower part of the six-dimensional robot treatment bed 1. The radiation treatment head of the accurate stereotactic radiosurgery treatment device can perform 90-degree (or + / -45-degree) rotation around an X axis so that rays can be transmitted in a 4pi non-coplanar track.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a precise stereotactic radiosurgery treatment device. Background technique [0002] Stereotactic precise radiotherapy technology adopts multi-beam, non-coplanar, high dose rate, and small-field irradiation to focus on the center of the tumor lesion, and adjust the beam intensity to make the dose distribution within the submillimeter range of the edge of the target volume rapidly. Decrease, reduce the damage to the surrounding normal tissue, expand the adaptability of radiation therapy, and significantly improve the patient's curative effect. However, the implementation of this technology puts forward higher requirements for the accuracy of treatment equipment, planning, positioning, and treatment. The existing stereotaxic radiation therapy device with an accelerator as a radiation source is a rotary motion system composed of a vertical cross between the rotation axis...
