Description
Technical field
The utility model belongs to technical field of medical equipment, occurs more particularly to a kind of rotating electron rifle annular X-ray
Device.
Background technique
In medical imaging field, x ray generator is the core equipment of X ray image equipment.X ray generator generates X
After ray, Radiolucent object, the ray through overdamping is got on detector later, and detector receives X-ray and generates figure
As data.
The basic principle of x ray generator is that the electronics that electron gun generates passes through the acceleration of electric field, is beaten later in metallic target
Upper (this metallic target is generally tungsten alloy), makes the free electron of the part of atoms on metallic target to high energy order transition later, subsequent
This high level free electron discharges photon to low energy order transition.This photon is x-ray photon.In above structure, electronics
Rifle and metallic target are encapsulated in a glass container, are vacuum state in container.
Among the above process, about 1 percent conversions of electric energy are fully entered for X-ray, remaining 90 about percent
Nine energy converts for heat.Therefore in order to lasting generation X-ray, metallic target has very big thermal capacity, Huo Zhejin
Belong to the heat generated on target to allow for quickly conducting.Due to one of the electronics constant bombardment metallic target after accelerating
The temperature in the region of very little, this region can be very high, and prolonged bombardment will lead to metal evaporation herein, influences subsequent X and penetrates
The generation of line.In order to solve this problem, metallic target has been designed to discoid and can be rotatable about an axis, and allows electron beam to exist with this
The bombarded point of metallic target becomes toroid.But the problem of thus bringing is that the heat generated on rotating metallic target is difficult to export
(guaranteeing to allow heat that can continue to export while persistently rotation).So the problem of bringing is, x ray generator cannot continue to grow
The work of time, meanwhile, in order to guarantee the lasting unwrapping wire of a period of time, the volume of metallic target is bigger, is guaranteed with this bigger
Thermal capacity.The above problem results in that x ray generator volume is big, and weight is big, cannot continue unwrapping wire for a long time.Simultaneously because
The shell of vacuum chamber is glass material, easy to break, and metallic target wants long-time high speed rotation when working, and metallic target is easy to damage, into
And result in x ray generator and integrally easily damage, service life is very short.
Utility model content
The utility model aim is that in view of the drawbacks of the prior art, heat, type discharge can quickly be exported by providing one kind
Line, rotating electron rifle annular x ray generator with long service life.
The utility model to achieve the above object, adopts the following technical scheme that
A kind of rotating electron rifle annular x ray generator, including electron gun, anode scoring ring and detector rings, feature exist
In: the anode scoring ring fixed setting；The electron gun is arranged on the intracavitary rotary part of ring vaccum, around anode scoring ring
Axle center rotation.
It is further characterized by: the rotary part is annular bearing, and the electron gun is fixed at annular bearing
On inner ring.
Further: the annular bearing is located in vacuum (-tight) housing ring, and the vacuum (-tight) housing ring and anode scoring ring cooperatively form institute
State ring vaccum chamber.
There is ray window ring, the outgoing of ray window ring described in X-ray transparent on the vacuum (-tight) housing ring inner wall.
The X-ray of outgoing forms X-ray covering of the fan；The X-ray covering of the fan of rotation covers the entire detector rings
Search coverage.
It is further further characterized in that: being provided with annular cooling water in the ring body of the anode scoring ring and/or detector rings
Road.
The ring vaccum chamber, anode scoring ring and detector rings are coaxially disposed side by side.
The electron beam of the electron gun transmitting, to directive anode scoring ring, is penetrated along the anode target annulate shaft after X ray excited
To the search coverage of the detector rings opposite with incoming position.
The utility model has an advantage that
1. solving the problems, such as that metallic target is easily damaged.Metallic target used in the utility model is the fixed metal of annular
Target, since metallic target no longer carries out the rotation of high speed around axle center, so that the stress condition of metallic target be made greatly to improve.
2. solving the problems, such as that x ray generator metallic target is not easy quickly to export heat.Used in the utility model
The cooling pipe of annular is built-in in endless metal target, cooling pipe is connected with extraneous radiator, cold in cooling pipe
But liquid takes away the heat that metallic target generates, and heat is dissipated in environment by extraneous radiator.It is generated on metallic target
Heat is rapidly exported, and then metallic target is caused to be hardly damaged.
3. solving the problems, such as that x ray generator can not continue unwrapping wire for a long time.The utility model is due to using
The fixation metallic target of annular, the coolant liquid in metallic target can rapidly export the heat that metallic target generates, and solve metal
The limited problem of the overheat and thermal capacity of target, so that x ray generator be enable to continuously send out ray for a long time.
4. solving the problems, such as that the x ray generator service life is short.The endless metal target of the utility model no longer rotates, metallic target
It is hardly damaged, so that the service life of x ray generator is greatly improved.
