Abstract
The utility model relates to a kind of tumor radiotherapy nuclear-magnetism MR to position fixed frame, including bottom plate, the beam orifice transmitted convenient for CT, analog machine, accelerator being set in the middle part of bottom plate upper side, be set to the adapter slot cooperated with the adapter item on CT, analog machine, accelerator in baseplate underside face and be set to the positioning slide for realizing positioning with the detent fit on thermoplastic film of floor peripheral.The utility model is mainly used for the guidance of tumor radiotherapy image, by positioning consistent locating rack with CT, analog machine, accelerator, it is ensured that with CT image co-registration, image of the precise positioning for accelerator treatment is guided.It is accuracy, reproducible in terms of thermoplastic film positioning, convenient for the neoplastic state of observation patient lies prone position abdomen and pelvic cavity.Patient comfort is improved by the way that rubber mat form-fit is arranged according to ergonomic designs theory.It is made of the glass fiber material of no hydrogen bond, avoids the influence that material generates image resolution ratio and clarity.
Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of tumor radiotherapy nuclear-magnetism MR positioning fixed frame.
Background technique
The positioning system used in MR positioning is completely the same with positioning system used in CT, analog machine, accelerator, with
Ensure to guide with CT image co-registration, image of the precise positioning for accelerator treatment, and existing tumor radiotherapy image draws
Leading positioning method can not cooperate thermoplastic film to be accurately positioned.Meanwhile NMR imaging requires specific functional groups in material, original under highfield
Sub-resonance will affect the resolution ratio and clarity of image, generate " artifact ".In addition when patient lies prone, the hard discomfort of fixed frame.
At present clinically used by 2D interfere with or disturb each other GRE, T1W1 sequence, by selection with antiposition image available " water " and
The independent image of " fat ".In the art, MRI detects hydrocarbon (C-H) key and oxygen hydrogen (O-H) key mainly to distinguish different groups
It knits.And most polyacrylonitrile (PAN) base carbon fibre raw material has a large amount of c h bond residuals in precursor preparatory phase, in spinning
Stage will use DMSO, and a variety of organic solvents such as DMF have a large amount of C-H and O-H key residuals, cause such carbon fiber production
MRI bed board in actual use can with C-H the and O-H key in human tissue structure formed signal be overlapped, cause bed board
Shading on photo is influenced in MRI.
Summary of the invention
In view of the above-mentioned problems, the utility model provides a kind of tumor radiotherapy nuclear-magnetism MR positioning fixed frame.
To solve the above problems, the technical solution adopted in the utility model are as follows: a kind of tumor radiotherapy nuclear-magnetism MR positioning fixation
Frame, adapter slot and bottom plate including the beam orifice and bottom surface (downside) setting that are arranged in the middle part of bottom plate and its upper side are all
The positioning slide of side setting, the beam orifice when CT, analog machine, accelerator transmission for using, convenient for observation patient lies prone
The neoplastic state of position abdomen and pelvic cavity, adapter slot realizes positioning with the adapter item cooperation on CT, analog machine, accelerator, fixed
It is provided with location hole on the slide of position, can realize and position with the detent fit on thermoplastic film.
The top of the plate top surface is provided with head cushion, middle part is provided with chest cushion, abdomen cushion and pubis
Backing plate, lower part are provided with genitals cushion and thigh cushion, and wherein chest cushion and abdomen cushion are distributed in the surrounding of beam orifice,
And above each component is distributed according to organization of human body and designs, and comfort level when patient lies prone can be improved.
The bottom plate is the glass fiber material without hydrogen bond, avoids what material generated image resolution ratio and clarity
It influences.
For glass fiber material, since most of material is built upon in the chemical structure of silicon substrate, fiber itself only can
There are silicon oxygen (Si-O) keys, do not conflict on MRI signal map with carbon spectrum and hydrogen spectrum: carbon spectrum exists in 50.3MHz, hydrogen spectrum
200MHz, and silicon spectrum is in 39.7MHz.So shade of the bed board made of glass fibre on image can be stayed than carbon fiber bed board
Under shade it is much smaller.
CT described above, analog machine, the positioning pin on adapter item and thermoplastic film on accelerator are existing standard
The product of model.
The utility model provides a kind of tumor radiotherapy nuclear-magnetism MR positioning fixed frame, is mainly used for drawing for tumor radiotherapy image
It leads, by positioning consistent locating rack with CT, analog machine, accelerator, it is ensured that with CT image co-registration, precise positioning is used for accelerator
The image of radiotherapy guides.It is accuracy, reproducible in terms of thermoplastic film positioning, convenient for observation patient lies prone position abdomen and
The neoplastic state of pelvic cavity.According to ergonomic designs theory, meet human body physiological characteristics, by the way that rubber mat form-fit is arranged, mentions
High patient comfort.It is made of the glass fiber material of no hydrogen bond, avoids material and image resolution ratio and clarity are generated
Influence.

Specific embodiment
As described in Figure, a kind of tumor radiotherapy nuclear-magnetism MR positions fixed frame, including the transmission being arranged in the middle part of bottom plate 1 and its top surface
The positioning slide 8 of the adapter slot and the setting of 1 periphery of bottom plate of hole 4 and bottom surface setting, the beam orifice 4 is for CT, simulation
It is used when machine, accelerator transmission, convenient for the neoplastic state of observation patient lies prone position abdomen and pelvic cavity, adapter slot and CT, simulation
Positioning is realized in adapter item cooperation on machine, accelerator, is positioned and is provided with location hole on slide 8, can be with the positioning on thermoplastic film
Positioning is realized in pin cooperation.
The top of 1 top surface of bottom plate is provided with head cushion 2, middle part is provided with chest cushion 3,5 and of abdomen cushion
Pubis backing plate 6, lower part are provided with genitals cushion 9 and thigh cushion 7, and wherein chest cushion 3 and abdomen cushion 5 are distributed in transmission
