Description
Technical field
The utility model relates to a kind of pair of target surface X-ray tube.
Background technology
Core component as the imaging device in the medical institutions such as hospital, X-ray tube produces X ray, X ray penetrates from window, a certain position or whole body to human body scan, the energy of part ray is absorbed by tissue, and a part of ray passes human body and is received by the receiver, and produces signal, process through background computer, obtain the image that available phosphor screen shows.Comprise core component---target disc in the X-ray tube.Cathode filament is heated a large amount of electronics of rear generation, is accelerating under the High Pressure, and electronics bombards target surface at high speed, thereby produces X ray.At present, the X-ray tube of using on the market is the bulb of bifocal (or three warmers) point of common target disc, and the ray of outgoing is the X ray of single spectrum, can only produce a kind of ray of character, or be hard ray, or be soft ray, can not utilize same X-ray tube to produce multiple ray of different nature.When being hard ray, can only be applied on a certain machine, such as CT machine, X-ray machine; When being soft ray, can only be applied to X-ray machine, milk-line machine of soft ray etc.For medical institutions, can only buy various equipment and satisfy the diagnosis needs.This has just increased the input cost of medical institutions to equipment, and simultaneously, the equipment of simple function has also caused the waste of resource indirectly.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of two target surface X-ray tubes that can increase the medical imaging device function, realize dual-use are provided.
The technical scheme that the utility model adopts is: the utility model comprises shell, negative electrode and rotarting anode, described negative electrode and described rotarting anode are separately positioned on the two ends of described enclosure, described rotarting anode comprises target disc, the rotor that is fixedly connected with described target disc, be arranged on the stator of described rotor periphery and the fixed axis that is rotatably assorted with described rotor, be provided with cathode taps at described negative electrode, be respectively arranged with hard ray filament and soft ray filament in described cathode taps, annular section corresponding with described hard ray filament on described target disc is set to rhenium tungsten target face, and the annular section corresponding with described soft ray filament is set to the molybdenum target face.
Described hard ray filament and the projection of described soft ray filament on described target disc are along outside same radially inside and outside distribution of described target disc center line.
Described hard ray filament and the projection of described soft ray filament on described target disc are along the outside Different Diameter of described target disc center line to inside and outside distribution.
The beneficial effects of the utility model are: because the utility model comprises shell, negative electrode and rotarting anode, described negative electrode and described rotarting anode are separately positioned on the two ends of described enclosure, described rotarting anode comprises target disc, the rotor that is fixedly connected with described target disc, be arranged on the stator of described rotor periphery and the fixed axis that is rotatably assorted with described rotor, be provided with cathode taps at described negative electrode, be respectively arranged with hard ray filament and soft ray filament in described cathode taps, annular section corresponding with described hard ray filament on described target disc is set to rhenium tungsten target face, the annular section corresponding with described soft ray filament is set to the molybdenum target face, so, by heating described hard ray filament, produce electronics and bombard described rhenium tungsten target face, produce hard ray, when heating described soft ray filament, produce electronics and bombard described molybdenum target face, produce soft ray, thereby realize that an equipment can produce the function of two kinds of rays, realize dual-use, relatively reduce the input cost of medical institutions to Medical Devices, also increased the utilization ratio of Medical Devices.
Because described hard ray filament and the projection of described soft ray filament on described target disc are along outside same radially inside and outside distribution of described target disc center line, perhaps, described hard ray filament and the projection of described soft ray filament on described target disc are along the outside Different Diameter of described target disc center line to inside and outside distribution, so, filament adopts different set-up modes, the electronics that can guarantee different filament generations is beaten on the target surface that requires separately, to produce different X ray, satisfies different requirements.
