Description
Technical field
The present invention relates in the 3D of tumour radiotherapy technical field, more particularly to a kind of accurate radiotherapy localization product of tumour
Individuation printing manufacture method and products thereof.
Background technology
At present, tumor patient carry out radiotherapy when Postural immobilization solution be radiotherapy localization film and/or vacuum pad,
It is aided with carbon fiber and fixes supporting plate, headrest.Radiotherapy localization film/vacuum pad, headrest, carbon fiber fixed plate etc. constitute a set of Postural immobilization
Device.Patient is diagnosed as tumor patient and determines to plan to implement after radiotherapy, and vacuum pad, completion film/true are filmed/make to film room
After sky pad, then to CT orientation room, put on body position fixing device (thermoplastic film/vacuum pad) and carry out tumour CT positioning, obtain patient and swell
The CT images at knurl position, and pass to after the design that TPS carries out radiotherapy treatment planning.Confirming the feasibility of radiotherapy technology and plan
After checking, patient puts on the body position fixing device and carries out interval procedure to accelerator computer room again.
There is following defect in existing technology：
(1) during interval procedure, because the material of the products such as radiotherapy localization film/vacuum pad/foam headrest is all non-hard
Material, as long as patient body is somewhat moved or weight distribution changes, body position fixing device will produce deformation, it is impossible to effectively
The slight movement of patient is limited, the patient body-surface profile for being most suitable for carrying out radiotherapy can not be more embodied, so as to produce inevitably
Error.
(2) in addition, the radiotherapy localization film of hot compress plastotype and the locating pad for vacuumizing plastotype are all by relatively rough material
It is fabricated by, it is impossible to patient body is carried out well moulding, it is impossible to embody patient body-surface profile details, the positioning provided
Precision does not reach the required precision of accurate radiotherapy completely.
(3) fixation of radiotherapy localization film/between vacuum pad and carbon fiber firm banking, whole body position fixing device and treatment
The pendulum position of fixation, technician between equipment bed board is instructed and patient is to factors such as the understandings of guidance, can all introduce error, cause to swell
The problems such as treatment precision of knurl is high, tumour Partial controll rate is not high.
The content of the invention

Printing.
Direction when being lain low by patient is defined (i.e. view direction in Fig. 2), and hollow out fusion treatment, net are made in the left side of product
Porosity reaches 36%, during facilitating patient to lie into positioner, and product is turned on treatment technician and not only flexibly but also had not allowed frangibility；Also it is
Patient provides more comfortable treatment experience.In addition on one side, upper part product edge makees edge stripization processing；Also edge strip is done in lower part
Change is handled, and integrated rotation fixed locating stud 3.When patient puts position, as long as rotation fixed locating stud 3 just can be realized to positioning dress
The fixation on top is put, after the completion for the treatment of, rotational positioning pin 3 just can cancel the fixation to device, allow patient to go out from fixing device
Come；
Product Part I and positioning product second are connected using axle.
Specific process is as follows：1st, patient and accelerator table are swept using noninvasive high-resolution imaging technology
Retouch, obtain both 3-D view, and this image is transferred to the image reconstruction of 3D printer by data fidelity Transmission system
System, carries out the moditied processing of image；
2nd, according to 3-D view (semi-finished product, no fixation of the accurate radiotherapy localization product of three-dimensional image reconstruction tumour of patient
The 3-D view of solution)；
3rd, rebuild fixed according to the 3-D view (semi-finished product image) of accelerator table and the accurate radiotherapy localization product of tumour
The 3-D view of the fixing solutions of position product, and the 3-D view of product is merged with the 3-D view of fixing solutions
Together, the 3-D view of the accurate radiotherapy localization product of complete novel tumor is obtained；
4th, product 3-D view is transferred to 3D printing terminal, printed using by the qualified material of clinical test,
Obtain the accurate radiotherapy localization product of novel tumor.
The use process of the present invention is as follows：
1st, obtain after the accurate radiotherapy localization product of novel tumor, hospital's tumour radiotherapy center carries out the examination of product,
By rear, patient is resetted with product；
2nd, reset after passing through, patient carries product and carries out tumour radiotherapy room progress position pendulum position：Patient lies in product
On, two parts close up fastening up and down, and product bottom is directly by 4 positioning products and therapeutic equipment bed board steady pin 4 with accelerating
Device therapeutic bed is fixed, after fixing, and can directly carry out radiotherapy.
