Description
Technical field
The present invention relates to core medical equipment field, and in particular to a kind of proton therapeutic based on MRI and detection frame are integrated
Mechanism.
Background technology
Proton therapeutic is that a kind of be irradiated using the proton with certain energy to tumor tissues reaches therapeutic purposes.
Current proton therapeutic appts realize the quick x-ray scanning before treatment by CT, and tumor focus is positioned, but this imaging
Technology resolution ratio is relatively low, and the positioning to patient's tumor tissues not enough can not be accurately carried out in line imaging when treating, and
With certain radioactivity.
MRI is very ripe as the application of lesion localization in clinic, without ionising radiation, and with preferably soft
Organize resolution ratio and whole process can be carried out in Patients During Radiotherapy in line imaging, be the optimal selection of current clinical medicine imaging.
But MRI is used for main field when in proton therapeutic can produce influence to the distribution of the dosage of proton beam, and normal cell may be damaged,
The precision and safety for the treatment of are have impact on, therefore it is particularly significant to solve influence of the magnetic field of MRI device to proton beam.
The content of the invention
In view of the deficiencies of the prior art, it is an object of the invention to provide a kind of proton therapeutic based on MRI and inspection
Frame integrated mechanism is surveyed, to realize the Proton therapy system by MRI in line imaging, while solving MRI magnetic field in treatment
The influence of proton beam dose distribution.
The present invention is realized by following technical scheme：
A kind of proton therapeutic based on MRI and detection frame integrated mechanism, it is characterised in that：Include the rotation of proton medical system
Frame, battery lead plate, proton therapeutic head, MRI device, sick bed, supporting construction, described battery lead plate include positive and negative electrode plate,
Positive and negative electrode plate is respectively symmetrically installed on both sides inside proton medical system rotary frame, and proton therapeutic head is lifted on proton doctor
Treat above the middle part in system chassis, supporting construction, which is located in the underface of proton medical system rotary frame, supporting construction, pacifies
Equipped with MRI device, MRI device middle opening is that proton therapeutic proton beam can be in the centre of MRI device by providing space, sick bed
Passed in and out in opening, tuning on-line is carried out to patient's tumor focus by MRI device, guiding Proton therapy system is carried out to patient
Treatment；Formed simultaneously between positive and negative electrode plate a certain size, direction and beam direction and the perpendicular electric field of magnetic direction,
With electric field force come Lorentz force of the offset magnetic field to proton.
A kind of described proton therapeutic based on MRI and detection frame integrated mechanism, it is characterised in that：The MRI device
Middle opening part in leave sufficient space and penetrate proton beam for proton therapeutic hair treatment is irradiated to human body.
A kind of described proton therapeutic based on MRI and detection frame integrated mechanism, it is characterised in that：The battery lead plate is consolidated
Due in supporting construction.
A kind of described proton therapeutic based on MRI and detection frame integrated mechanism, it is characterised in that：The supporting construction
Insulation.
It is an advantage of the invention that：
The present invention by battery lead plate apply a certain size, offset matter with beam direction and the perpendicular electric field of magnetic direction
Lorentz force suffered by son, so that the offset of proton beam is zero so that MRI device body foci can be carried out it is online into
Co-treatment head is treated from different perspectives while picture, can be achieved to determine patient's tumor focus while proton therapeutic
Position, while improving the treatment positioning precision of proton.
