In proton therapeutic appts, the line of Beam Transport Systems blocks mechanism.
Background technology
Proton therapeutic technology is currently a significant frontier nature research field in medical oncology research.Due to
It is few that proton beam has other scattering, and penetration power is strong, the features such as dose distribution is adjustable, it is possible at fixed point alignment tumor tissues, therefore can
Reach to protect the normal cell of patient the most to greatest extent, and all energy are completely used for killing the mesh of cancerous cell
's.
SC200 proton therapeutic appts is mainly by groups such as proton precessional magnetometer main frame, Beam Transport Systems and rotary supports
Become: proton precessional magnetometer provides the proton of suitable dose for therapeutic room；Rotary frame is capable of the location of tumor in any direction
With treatment, and guarantee that accuracy is within 1mm；Beam Transport Systems is between proton precessional magnetometer main frame and rotary frame, main
The proton beam that accelerator produces it is transported to therapeutic room, to make therapentic part be irradiated by enough energy, be proton therapeutic
One of important feature in device.
Proton beam used by treatment needs to carry out the specific modulation need with satisfied treatment according to the situation of tumor tissues
, therefore in SC200 running, proton beam is Beam Transport Systems to be passed through after cyclotron accelerates to 200Mev
In the device such as degrader, collimator, selection slit and beam monitoring selection after get to each therapeutic room and with
Treatment head connects.Specifically, for the operation that the armarium enabling so complexity is safe and reliable, patient is especially ensured
Safety with staff, it is contemplated that proton therapy equipment, under abnormal operational conditions, is badly in need of the proton beam to local for some reason
Stream quickly blocks, and implements that component home is rushed to repair replacing or the selection to proton beam is debugged, and do not affect miscellaneous part
Properly functioning.Quick blocking device ripe in the market typically uses electrichydraulic control class valve, it is impossible to enough realization is quickly hindered
Disconnected purpose, and precision do not reaches far away design requirement, it is therefore desirable in Beam Transport Systems, a kind of line of design blocks machine
Structure ensures safety and the reliability of proton therapeutic appts.
