Description

A kind of neutron capture therapy system
Technical field
The utility model relates to radiation therapy technology field more particularly to a kind of neutron capture therapy systems.
Background technique
Boron neutron capture therapy (Boron Neutron Capture Therapy, BNCT) is a kind of " medical instruments combination ", peace The better biological targeting binary radiotherapy mode of full property, with the excellent of the means such as radiotherapy, chemotherapy, heavy particle therapy from principle Point is most hopeful to realize the wonderful dream that the mankind eradicate tumour.BNCT treatment will be first by that will have the nontoxic of close tumor tissues Take boron infusion of medicine blood of human body, it is multi-direction suitable using epithermal neutron wait take boron (boron -10) drug-rich after tumor tissues Shape irradiates tumor locus, and -10 nucleic of boron in neutron and cancer cell meets and occurs nuclear reaction, the alpha particle of releasing and - 7 particle of lithium has very strong lethality to cell, and fragmentation effect is higher than existing X-ray, gamma ray radiotherapy and proton and puts It treats, the side effect of BNCT is smaller, and with taking further increasing for boron drug parent's tumor effect, BNCT normal tissue Damage will further decrease.The expansion in extensive range, and having can treat proton, heavy particle therapy not of the tumour indication of BNCT Dissipate the tumor cases that recur again after type malignant tumour or treatment, such as in glioblastoma multiforme (the pernicious cancer of the brain), multiple Hair property head and neck cancer, maligna element cutaneum carcinoma, metastatic liver cancer etc., therapeutic effect is significantly better than existing treatment technology.
The core equipment accelerator of BNCT facility preferably long-term continuous operation after start-up, both may insure to accelerate in this way The operation stability of device can also be improved the service life of accelerator.More than two therapeutic rooms and one is arranged in BNCT facility Radionuclide produces terminal, and line switches between different therapeutic rooms between treatment phase;In the non-treatment period, line is switched Terminal is produced to radionuclide, realizes making full use of for accelerator line, realizes that equipment investment business efficiency maximizes.In this way The patient that the time spent in preparation is less than previous receiving irradiation before requiring patient to irradiate receives irradiation in exposure cell Time, it is ensured that pendulum position and irradiation position in place is completed in current patents before line switching.
In addition, clinically generalling use the radiation modality treatment tumour of dose fractionation to improve the safety of radiotherapy Primary high-dose irradiation is divided into light exposure several times by patient, make full use of human normal cell's repair ability that will be damaged The normal cell reparation of wound.BNCT also has a possibility that dosage segmentation treatment, appropriate to increase irradiation number, reduces each The time of irradiation.With the shortening of patient's irradiation time, time is possible to have been over irradiation time, leads to a photograph It penetrates room to have treated when line need to be switched to another exposure cell, but there are no ready by the patient of this exposure cell.
BNCT carries out treatment of cancer using epithermal neutron beam, and neutron collides with air and other media, will cause Medium is activated, and generates artificial radioactivity.With the increase of line runing time, irradiating indoor artificial radioactivity can gradually tire out Product.If health care worker frequently enters and leaves exposure cell, being likely to result in year intergal dose is more than national personal profession limit value rule It is fixed.
Based on the above situation, we it is necessary to design a kind of neutron capture therapy system for being able to solve the above problem and trouble The method that person quickly puts position.
