Description
Technical field
The invention belongs to technical field of medical instruments, is related to a kind of proton therapeutic appts, more particularly to a kind of medical proton
Beam rotary frame.
Background technology
Cancer (malignant tumour) has turned into one of the main reason for countries in the world resident's Died Of Disease, and every country cancer is controlled
The new technology for the treatment of continues to bring out.What the radiotherapy in traditional treatment of cancer was mainly taken is X ray, gamma-rays and electronics
Beam, the distribution of its physical dosage and biological effect all injure the normal cell of tumor vicinity to varying degrees, and dosage has
It is also low to imitate utilization rate；Though the biological effect of neutron and negative π particles is good, physical dosage distribution is bad, and normal tissue damaged
Greatly, preferable treatment method it is not.
Proton is the basic fine particle of constituting atom core；Heavy ion is atomic nucleus of the atomic weight compared with thick atom, conventional
Such as carbon ion.Proton or carbon ion accelerate to about 70% light velocity via synchrotron, are brought out injecting human body.It is swollen reaching
Before knurl focus, ray energy release is few, after focus is reached, the ray meeting big energy of abrupt release, forms entitled " Prague
The energy release track at peak ", it is to be directed to tumour " stereotaxis explosion " that whole therapeutic process, which cans be compared to, and tumor focus can be entered
The strong irradiation of row, while avoid irradiating normal structure again, realize that curative effect maximizes.The advantages of proton therapeutic is to make radioactive ray
Energy peak alignment tumor focus at, at tumour by maximum exposure dose, preneoplastic normal cell generally only by
1/3~1/2 peak dose, the normal cell at tumour rear portion substantially preserve from.Out of proton physical characteristic with regard to energy
Conclude that it is more more advantageous than conventional radiotheraphy method.In recent decades, 100,000 cancer patients have been had more than and have obtained proton therapeutic, its
Superiority obtains extensive clinical verification.
Proton therapeutic appts are the large medical equipments of new healing tumour in the world, rotary frame (Gantry) therein
With the characteristics of structure is big, precision is high.The principle of rotary frame is：If proton therapeutic only with a direction of illumination, skin with
Normal cell between tumour at least will be formed different degrees of injury by 1/3 tumor radiation dosage, to reduce this part damage
The burnt skin ratio value of evil increase treatment, so a therapeutic process is needed from different directions to irradiate, is divided into multiple spokes by accumulated dose
Direction is penetrated, the dosage that such normal structure is subject to just is greatly reduced.The effect of rotary frame is exactly to support proton beam from difference
Angular illumination to the mechanical structure of focus, therefore almost all of proton therapy center is all configured with more rotary frames.Rotation
The high energy conveying equipment such as magnet is carried on favourable turn frame, weight is from 100~200 tons, and running accuracy requires very high, design
Such mechanical structure is extremely challenging.
