Embodiment 1
At present, the radiation therapy technology of tumour has been enter into the accurate epoch, i.e. accurately irradiation position and accurately dosage Give, therefore generate the wide variety of image guided radiation therapy technology IGRT (Image-Guided in current radiotherapy field ) and IMRT technology IMRT (Intensity-Modulated RadioTherapy), RadioTherapy this two The application of radiotherapy new technology substantially increases radiotherapy level, so they are referred to as the revolutionary change of radiotherapy technology of 20th century Change.But from decades clinical application practice and from statistical significance interpretation of result, this technical revolutionary variation, not band To produce revolutionary change or raising in terms of oncotherapy effect or local control rate.This is primarily due to, and above-mentioned two For technology is the accurate distribution based on the accurate physical location of tumour and physical dosage, tumor patient individual is considered Biology in terms of (metabolism, weary oxygen, radiation sensitive) characteristic and difference.If can be in this two new technologies of IGRT and IMRT On the basis of checking and life after irradiation are given to the position of irradiation and dosage from the biology angle of tumor patient individual Research is given in terms of thing effect and is evaluated, i.e., from biological target area (Biological target volume, BTV) and biological suitable The radiotherapy of research tumour, will control the radiation of tumour in terms of shape intensity modulated radiation therapy (Biological IMRT, Bio-IMRT) Treatment technology attains a new height.Particularly radiation dynamic treatment of tumor, leukaemia and vascular plaque, make radiotherapy produce revolution The change of property.
Target of the present utility model is exactly to develop a kind of being set in beam (In-beam) high energy radiotherapy with PET image displaying functions Standby open loop PET+Linac, this radiotherapy apparatus integrates 45MV High-energy Electron Linacs and PET is imaged, and is a new generation Biology radiotherapy equipment, it is possible to achieve from biological target area (Biological target volume, BTV) and tumour pair Biological intensity-modulated radiation therapy (Biological IMRT, Bio- are implemented to tumour in terms of the biological effect of sigmatron IMRT).Because showing by substantial amounts of basis and clinical research test, the 45MV sigmatrons of high energy acclerator transmitting When irradiating tumour patient, while tumour cell is killed, the oxygen 16 (16O) of tissue is excited, carbon 12 (12C) produces positive electron hair Core oxygen 15 (15O), carbon 11 (11C) etc. are penetrated, patient is scanned imaging with PET imagings immediately after irradiation or treatment, determines that X is penetrated The position of line irradiation and the dosage distribution of irradiation, realize treatment and live body (in-vivo) biometric authentication and biological effect point Analysis is carried out simultaneously, can also realize the radiotherapy (Bio-IGRT) of biology image guiding, so as to truly realize essence True three dimensional biological conformal modulating radiotherapy (Bio-IMRT) and checking.
The key issue run into is to need to prove crystal structure of the 45MV sigmatrons to pet of high energy acclerator transmitting Whether generation is destroyed, therefore needs to carry out following experiments investigation, and the crystal bar in pet equipment, crystal block are attached separately into accelerator To carry out long-term tracking test below treatment head side and bed board.
Crystal block present position is located at accelerator treatment head side, in the range of high energy acclerator x-ray scatter, but not In the range of direct projection, color contrast of the observation crystal block after pre-irradiation can prove x-ray in clinical treatment to pet equipment In crystal structure influence.Crystal block is constantly in experimental stage, 10 of experiment in January, 2014 to 11 month periods Month, average one week 6 day treatment time, one day average 3 patient.Crystal block is illustrated in figure 2 positioned at accelerator treatment head Comparison diagram before and after being tested during side.Crystal block color is contrasted according to picture and detects by an unaided eye change less, it was demonstrated that scattering condition Under, influence that the scattering of high-energy ray is produced to crystal block is simultaneously little.
The position of crystal bar is located at the lower section of bed board, and residing region is patient chest or so region, in the direct of x-ray In range of exposures, the standing time of crystal bar never has from January to November to be taken, 10 months of experiment, average one week 6 Its treatment time, one day average 3 patient.According to the contrast after pre-irradiation, as shown in figure 3, shadow of the x high-energy rays to crystal bar Sound is also little.
Conclusion:This experimental verification pet crystal structures are in the time of 10 wheat harvesting periods, in the straight of accelerator high-energy ray Under the conditions of penetrating and scattering, the fact that crystal color change is little.Illustrate open loop pet+linac equipment within 10 wheat harvesting period times The possibility of influence is produced in the absence of linac high-energy ray divided ring pet crystal structures.
Embodiment of the present utility model described in detail above, still, the utility model is not limited to above-mentioned embodiment party Detail in formula, in range of the technology design of the present utility model, can be carried out many to the technical solution of the utility model Simple variant is planted, these simple variants belong to protection domain of the present utility model.
It is further to note that each particular technique feature described in above-mentioned embodiment, in not lance In the case of shield, it can be combined by any suitable means.In order to avoid unnecessary repetition, the utility model is to each Possible combination is planted no longer separately to illustrate.
In addition, can also be combined between a variety of embodiments of the present utility model, as long as it is not disobeyed Thought of the present utility model is carried on the back, it should equally be considered as content disclosed in the utility model.
