Gamma radiation therapy apparatus with fixed frame

Abstract

The invention discloses a kind of fixed rack Gamma ray treatment plant.installs the Gamma ray radiating system on the cross arm which is in the U shape rack,in two vertical open mouth arms of the the rack vertical to the outside direction separetely installs fixed axis to permanently connect with the column, two columns vertical are fixed above the foundation.in the rack two vertical strokes arms approach to cross arm place the endophragm is separately installed the X ray, each X ray source ties mouth direct to the relative X beam receive screen direction, two groups X ray channel orthogonal intersection to a point, this focal point superposes with the radiating system radioactive source focal point O.The invention uses the U shape rack is fixed motionless, the structure is greatly simple, does not need the transmission system and the balance gear, the security is enhanced.

Description

technical field [0001] The invention relates to a fixed frame gamma ray therapy equipment. Background technique [0002] The radiation device of the gamma ray therapy equipment is a key part of the equipment. Multiple cobalt-60 radiation sources are installed inside the device. Cobalt-60 will not only kill tumor cells but also damage normal human cells, so the radiation source must be made of a material with a certain thickness. shielding, which makes the radiation device bulky and heavy. To rotate a large and heavy radiation device not only requires a high-power drive source and a safe and reliable transmission device, but also the movement mechanism and balance mechanism of the radiation device are relatively complex in structure, and the supporting structure of the entire equipment needs to be large and strong. [0003] Existing gamma ray therapy equipment only has a single treatment function. Before the treatment, the detection and location of the lesion should be carri...

AI Technical Summary

Problems solved by technology

To rotate a large and heavy radiation device not only requires a high-power driving source, a safe and reliable transmission device, but also the movement mechanism and balance mechanism of the radiation device are relatively complex in structure, and the supporting structure of the entire equipment needs to be huge and strong.

[0003] Existing gamma ray therapy equipment only has a single treatment function. The detection and location of the lesion must be carried out before the treatment. The measurement of the position of the lesion is not carried out during the treatment. After the treatment, the treatment effect of the lesion can be checked.

Since real-time detection cannot be performed during the treatment process, the treatment error cannot be corrected in real time, and the treatment accuracy cannot be guaranteed to be high.
