Abstract
The invention relates to a manufacturing method for conformal adjusting collimation device. The invention includes steps: 1. the macromolecule foam is mounted in the specially made multi-function locating frame; 2. according to the shape in different visual angle and the requirement for the therapeutic plan, the conformal shape matched with the shape and the size of the tumour or conformal adjusting positive mold are made of the macromolecule foam; 3. the melting shielding material is poured in the depression around the positive mold and freeze it. Install it when using, it solves the technical problems of fussy method of making, low efficiency and low positioning accuracy.
Description
Technical field
The present invention relates to field of radiation therapy, be specifically related to the manufacture method of conformal intensity modulated collimator.
Prior art
Existing collimating apparatus all is to utilize tumour shape at a certain visual angle in the space to make the formpiston of separately suitable row or strength regulating compensating, and making tool by molten lead again is collimating apparatus with the former of certain shielding action.The formpiston that this mode is made is single, and collimating apparatus only comprises the shape of tumour single visual angle in the space, can only satisfy the suitable shape of tumour single direction or transfer strong demand, promptly has only an irradiation field.And existing treatment plan is killing tumor cell to greatest extent, and the protection normal structure adopts that multi-angle is multi-faceted fit shape or accent massive exposure to tumour more.As collimating apparatus manufacturing technology routinely, need to make a plurality of collimating apparatuss, so that be complementary with tumour shape of different visual angles in the space, when implementing irradiation, irradiating angle of every replacing needs to change the collimating apparatus that is complementary, radiation therapy need interrupt.The mode of this molding and die change has following drawback: the processing of formpiston is loaded down with trivial details, the location that is installed of repetition, and positioning error is bigger; The position of core rod is difficult to centering during casting; Shield is changed loaded down with trivial details, and medical and technical staff's labour intensity is big; The therapy apparatus inefficiency; Non-cutting time during patient's irradiation treatment is long.
Summary of the invention
The present invention will solve is that the method for making of existing collimating apparatus is loaded down with trivial details, and efficient is low, the bearing accuracy difference technical matters.
In order to solve above technical matters, the technical scheme that the present invention takes is:
A kind of manufacture method of conformal intensity modulated compensator is characterized in that, adopts the mode of casting to be produced on the collimating apparatus with shielding material a plurality of suitable shapes open country, and the shape of wild shape of suitable shape and tumour space different visual angles is complementary.
Specifically may further comprise the steps:
(1) the macromolecule bubble being washed one's hair material is placed in the special multi-functional posting;
(2), the macromolecule bubble is washed one's hair material make suitable shape or the suitable shape that is complementary with tumor shape and size and transfer strong formpiston according to the shape of tumour different visual angles in the space and the demand of treatment plan;
(3) with the shielding material of the perfusion of the pit around formpiston fusing, cool off.
Described have a plurality ofly according to the tumour formpiston that the shape of different visual angles is made in the space, and be positioned at same bubble and wash one's hair on the material.
The collimating apparatus of described multi-functional posting after with moulding used together.
After having adopted technique scheme, owing to be to wash one's hair at same bubble to process a plurality of formpistons on the material, reduced the installation number of times of material, reduced the resetting error, both can realize suitable row and transfer by force irradiation separately, suitable shape and accent are united two into one by force.Collimating apparatus once is installed after the success, cooperates the automatic die changing mechanism of my company's development, when changing irradiating angle tumour is carried out radiation therapy, will adjust to correct position with the irradiation field that this angle is complementary automatically.Thereby the method for making that has solved existing compensator is loaded down with trivial details, and efficient is low, the bearing accuracy difference technical matters.

Embodiment
A kind of manufacture method of conformal intensity modulated compensator may further comprise the steps:
(1) the macromolecule bubble being washed one's hair material is placed in the special multi-functional posting;
(2), the macromolecule bubble is washed one's hair material make suitable shape or the suitable shape that is complementary with tumor shape and size and transfer strong formpiston according to the shape of tumour different visual angles in the space and the demand of treatment plan;
(3) with the shielding material of the perfusion of the pit around formpiston fusing, cool off.
As Fig. 1, shown in 2, the bubble of appropriate size is washed one's hair after material puts into special multifunctional frame, multifunctional frame is positioned corresponding positioning equipment (as 3 dimension milling machines), demand by treatment plan, the shape of tumour different visual angles in the space or the dose distribution of tumour zones of different are imported milling machine with the suitable data form, automatically process suitable shape or suitable shape band and transfer strong formpiston, as Fig. 3 and Fig. 4, shielding material with the perfusion of the pit around formpiston fusing, collimating apparatus behind the casting, as shown in Figure 5, together with posting, be installed on the radiotherapy apparatus, finish intended function.
Claims (4)
1, a kind of manufacture method of conformal intensity modulated collimator is characterized in that, adopts the mode of casting to be produced on the collimating apparatus with shielding material a plurality of suitable shapes open country, and the shape of wild shape of suitable shape and tumour space different visual angles is complementary.
