Description
Technical field
The invention belongs to technical field of medical instruments, a kind of be related in terms of dynamic heavily loaded support application specifically a kind of is used
Self-aligning roller supporting platform in medical proton beam rotary frame.
Background technology
Cancer (malignant tumor) has become the one of the main reasons of countries in the world resident's Died Of Disease, and every country cancer is controlled
The new technique for the treatment of is continued 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
Effect utilization rate is also low；Though the biological effect of neutron and negative π particles is good, physical dosage distribution is bad, and normal tissue was damaged
Greatly, preferable Therapeutic 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.Swollen reaching
Before tumor stove, ray energy release is few, and after focus is reached, the big energy of ray meeting abrupt release forms entitled " Prague
The energy release track at peak ", it is for tumor " stereotaxises explosion " that whole therapeutic process cans be compared to, and tumor focus can be entered
The strong irradiation of row, while avoid irradiating normal structure again, realizes that curative effect is maximized.The advantage of proton therapeutic is to make lonizing radiation
At energy peak alignment tumor focus, at tumor it is subject to maximum exposure dose, preneoplastic normal cell to be generally only subject to
1/3～1/2 peak dose, the normal cell at tumor rear portion are not substantially affected by injuring.From in proton physical characteristics 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 has obtained proton therapeutic, its
Superiority obtains extensive clinical verification.
At present the proton therapy center of successful operation all have bulky, involve great expense, construction period length and
It is difficult to the shortcomings of popularizing, and the proton therapeutic instrument that adopts of these proton therapy centers does not possess cancer cell is positioned
Function, it is therefore desirable to extra equipment is diagnosed to patient, determines cancer cell position, is then entered using proton therapeutic instrument
Row treatment.The developing direction of following proton therapeutic instrument main flow is miniaturization and integrated, subtracts the overall dimensions of proton therapeutic instrument
Little, shorten the construction period, reduces cost, and make diagnostic detection integrated with treatment, in order to the popularization of proton therapeutic instrument.
