Disk 111 has locking mechanism on dial 111, seat can be made no longer to turn for recording the angle that seat rotates when patient treats
It is dynamic.Fixing groove 112 is additionally provided on chassis 11, for fixing DR plates box 3.Backrest 14 is fixed on seat 13, is put in its rear
DR plates box 3 is set, it can be achieved that patient shoots rabat before radiotherapy.Backrest 14 is transparent organic glass material, does not influence observation irradiation
Light field is incident upon on DR plates box 3.There is vertical line 4 at same position among two sides before and after backrest 14, to be aligned in computer room
Both sides laser lamp ensures that seat is vertical with the holding of beam axis direction.
Diffuser screen 2 includes organic glass 21, adjusting rod 22.Organic glass 21 is connect with adjusting rod 22, for keeping ray flat
It penetrates, center is provided with a groove 211 being recessed inwardly, and several partition boards 212 are provided in groove 211, forms grid array.Side
It can be inserted into leads 2121 or poly (methyl methacrylate) plate 2122 in lattice array, doctor is according to the size of lung in patient's rabat, in lattice-array
It is inserted into several leads 2121 in row and forms lung shape, makes ray that can not penetrate, to protect lung tissue, does not set leads 2121
Place is filled up using poly (methyl methacrylate) plate 2122.212 side of partition board is equipped with positioning filament 213, and positioning filament can be various metal materials, penetrate
Line can not penetrate, and grid array shade can be formed on DR plates, and doctor is facilitated to be easy to enter 2121 shape of leads in grid Array interpolation
It is blocked at lung.
There is vertical line 4 in 2 front and back end centre position of diffuser screen, to be aligned accelerator computer room both sides laser lamp, makes scattering
Shield 2 opposing rays beam axis and keep vertical, each pre-irradiation should measure diffuser screen to seat distance, it is ensured that consistency.2 liang of diffuser screen
Side equipped with altitude scale 5 to ensure fractionation of radiation when diffuser screen high consistency.It is telescopic fixed that 11 bottom of chassis is equipped with
Position track 113, when use, can pull out track, and adjusting rod 22 can be fixed in positioning track 113.
DR plates box 3 includes box body 31 and fixed link 32.Fixed link 32 is removably inserted into fixing groove 112.Box body 31
DR board slots 311 are equipped with, the fixing buckle 312 that fixed DR plates are provided with around DR board slots 311 need to be by DR plates in body irradiation
DR plates in box 3 remove, and prevent the wasting of resources.
Vacuum pad 15 is arranged in fixing seat 1, internal to be filled with plastic particle；It is provided with aspirating hole on vacuum pad 15
151, after patient takes vacuum pad 15, be evacuated by aspirating hole 151, make 15 hardening plasticity of vacuum pad, can immobilized patients position.
15 immobilized patients of the vacuum pad ranging from lower part of the body does not block DR plates box behind, does not influence film magazine height to both sides oxter.
In the present invention, adjusting rod 22, fixed link 32 are scalable, are adjusted according to the height of different patients.
In the present invention, handrail 131 is provided on seat 13.
In the present invention, DR board slot length and width are 38-43cm, depth 2-3cm.
In the use of the present invention, patient is first allowed to be sitting in fixing seat 1, DR plates box 3 is inserted into fixing groove 112, shooting
Rabat；After shooting, DR plates box 3 is removed, and diffuser screen 2 is moved between fixing seat 1 and radioactive source；Rabat is compareed,
It is inserted into leads 2121 in grid permutation and forms patient lungs' shape to stop ray, it is in order to which lung is limited the quantity that lung, which blocks,
Too high dose irradiation in addition leads to treatment and the quality of life of the influence patient such as pneumonia.Extracting air out by aspirating hole 151 makes
15 plasticity of vacuum pad prevents its swing with immobilized patients.When need to repeatedly treat, height of seat and rotation angle are can record, it is convenient
Doctor calculates irradiation metering.
In the present invention, there is battery inside DR plates, have inductive device, digitized video is formed after taking pictures.Then network of computer room will
Digitized video can observe digitized video by uploading network, the computer outside such computer room by network.
The application method of systemic radiation therapy equipment of the present invention：
1. patient positions for the first time, first chair angle is returned to zero, ensures chair vertical in beam axis with both sides laser lamp
Direction, and seat back is recorded to metope distance.
2. the vacuum pad containing gas is placed on seat, patient is set to be seated on gassiness vacuum pad, and according to patient body position
So that vacuum pad is wrapped patient body, makes buttocks, crotch, two legs and both arms profile, and vacuum pad is evacuated to by vacuum with aspiration pump
It is moulding.
3. patient is made to open wide chest, adjusting height of seat makes cross laser lamp be directed at chest position, and is marked with marking pen
Note, while recording height of seat.
4. after DR plate box framves are inserted into seat, accelerator rack is rotated to 90 ° or 270 °, light field is opened and observes DR plate boxes
Position, adjustment film magazine height ensures that film magazine can be by human chest Bao Quan, and records film magazine height.
5. shooting normotopia DR plates with 2 or 3MU.
6. making patient back to radioactive source for 180 ° seat rotation, being again turned on light field and adjusting DR plate box height shooting back of the body position
DR plates, and record DR plate box height.
7. measuring patient body thickness and width, and required accelerator is measured with corresponding thickness solid Fluid Dynamics patient and is jumped
Number MU.
8. before treatment, DR plates are inserted into piece box position, vertical line is directed at both sides laser lamp before and after diffuser screen, and records scattering
Screen rotates accelerator rack to 90 ° or 270 ° to seat distance.DR is digital imagery, is compared with shadow without printing film.
Space part on diffuser screen, due to there is each grid to have wire above, lung will be being shown when taking pictures in not space
Grid lines is shown in lung images (image is shown on computers) while image, in this way it is seen that lung boundary
Coordinate (is similar to chessboard of go), as long as being plugged after leads with reference to corresponding coordinate when space and clapping a rabat again, in electricity
It is accurate to be confirmed whether to block lung on brain.
9. patient faces rack and is sitting on treatment seat, position is fixed with vacuum pad, while chest is marked alignment laser
Semiconductor probe is pasted onto before and after patients abdomen and chest goes out Shu Jinhang by 2121 blocking position of leads and treats by lamp.
10. removing semiconductor probe after going out beam, practical exposure dose and chest exposure dose are calculated, chest dosage is not
Foot point should be subject to benefit amount with subsequent electric wire.
11. seat is rotated 180 °, repeats 8-10 steps and carry out the treatment of back of the body position.
The protection content of the present invention is not limited to above example.Without departing from the spirit and scope of the invention, originally
Field technology personnel it is conceivable that variation and advantage be all included in the present invention, and with appended claims be protect
Protect range.
