Abstract
The invention discloses an X-ray radiation field indicating method, a beam limiting device and medical X-ray photographic equipment. The beam limiting device comprises at least one beam limiting body and a plurality of lasers, wherein the beam limiting body is used for determining a radiation field of an X-ray on a preset projection plane; an indicating area is surrounded by projection (on the preset projection plane) of projecting lines of the plurality of lasers; and the indicating area is overlapped with the radiation field. As the laser has little heat radiation, the temperature inside the beam limiting device is prevented from being excessively risen, thereby being beneficial for ensuring that the internal temperature is kept in a safe range, and the system stability is improved; and meanwhile a completely sealed shell can be conveniently adopted to prevent radiation leakage better.

A) most of electric energy of Halogen light converts heat energy into; Generally can only use the Halogen light luminous flux less than 2%; Heat and the light that does not utilize rise the device internal temperature of simulation roentgenogram launched field; Influence whole system stability and cause skin temperature to be difficult to drop to below the safety criterion, the outside of the device that is relatively independent of the roentgenogram launched field of perhaps having to place Halogen light, but this stereotype layer that causes radioprotective to be revealed has to occur breach;
B) relatively low luminous efficiency and the luminous flux utilization rate waste that causes the energy;
C) the high-power big electric current that causes also causes the cost of security protection aspect to rise;
D) because Halogen light can not be located immediately at the position of x-ray focus, often need reflecting mirror to realize this process, cause device complicated.
Summary of the invention
The objective of the invention is the deficiency to prior art, a kind of roentgenogram launched field indicating means, beam-defining clipper and medical X-ray photographic equipment of can energy savings, improving system stability and reducing cost is provided.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: a kind of X ray beam-defining clipper; Comprise at least one limit bundle body and a plurality of laser instrument; Said limit bundle body is confirmed the irradiation field of said X ray on preset perspective plane, and the projection of the incident line of a plurality of said laser instrument on said preset perspective plane crosses the indicating area, and said indicating area overlaps with said irradiation field.
Further, said irradiation field and indicating area are square.
Further, said laser instrument is selected from: yi word pattern laser instrument, cross laser instrument and point-like laser device.Laser instrument can only have a kind of, also can be multiple combination.
Further, said laser instrument has two, and it is cross laser instrument.
Further, said laser instrument has four, and it is the yi word pattern laser instrument.
Further, said limit Shu Tiwei lead window.Said lead window has one or more.
Further, said laser instrument is connected with drive mechanism power.Can adjust the position and the angle of laser instrument through drive mechanism.
Further, the position of said laser instrument and angle determine that to the distance on preset perspective plane and the position and the size of roentgenogram launched field its calculating can realize through the mode of frame for movement, circuit or software by the focus of X ray.
A kind of medical X-ray photographic equipment comprises described X ray beam-defining clipper.
A kind of method of utilizing laser instrument indication roentgenogram launched field.This method can utilize the combination of a kind of laser instrument or multiple laser instrument to indicate irradiation field.
The invention has the beneficial effects as follows: 1), can not cause that the beam-defining clipper temperature inside excessively raises, be convenient to guarantee that internal temperature in safety range, has improved system stability because the heating of laser is little; Simultaneously, also be convenient to adopt totally enclosed frame better to prevent radiation leakage.2) laser power is low, has practiced thrift the energy, and power supply is simple, and cost is low and safe.3) can not need use reflecting mirror to realize the indication of roentgenogram launched field, simplified the structure of beam-defining clipper, reduced cost.
Description of drawings
Fig. 1 is the structural representation of beam-defining clipper first specific embodiment;
Fig. 2 is the structural representation of beam-defining clipper second specific embodiment.
The specific embodiment
Combine accompanying drawing that the present invention is done further explain through the specific embodiment below.
The X ray beam-defining clipper is used for the medical X-ray photographic equipment, and kind comprises automatic beam-defining clipper and manual beam-defining clipper.Beam-defining clipper comprises at least one limit bundle body and a plurality of laser instrument.The X ray that x-ray source penetrates is limit bundle by limit bundle body, and the irradiation field of this X ray on preset perspective plane confirmed by this limit bundle body.Irradiation field is square, like rectangle or square.Limit bundle body can have one or more, and it can be existing lead window.Laser instrument is used to indicate the irradiation field of X ray, and an indicating area is determined in the projection of the incident line on this preset perspective plane that a plurality of laser instrument penetrate, and this indicating area overlaps with irradiation field.Laser instrument can be selected from: yi word pattern laser instrument, point-like laser device and cross laser instrument; This yi word pattern laser instrument is meant that the laser projections line is at the collinear laser instrument of presetting on the perspective plane that is projected as; The point-like laser device is meant the laser instrument that be projected as luminous point of laser projections line on preset perspective plane, and cross laser instrument is meant the laser instrument that be projected as cross hairs of laser projections line on preset perspective plane.
As shown in Figure 1, it is first specific embodiment of the present invention.Beam-defining clipper comprises four yi word pattern laser instrument and four lead windows, only demonstrates 141,142 and two lead windows 121,122 of two laser instrument among Fig. 1.Four laser instrument can be about focus 100 symmetries of X ray.Irradiation field through the X ray behind lead window 121, the 122 limit bundles is square.The incident line of each laser instrument is at the straight line of presetting on the perspective plane 130 that is projected as, and a quadrate indicating area is determined in the projection of the incident line of these four laser instrument.Four limits of indicating area overlap with four limits of irradiation field respectively.In addition, for the incident line projection that accurately makes laser instrument overlaps with the limit of irradiation field, can regulate the position and the crevice projection angle of laser instrument through existing drive mechanism.The position of said laser instrument and angle determine that to the distance on preset perspective plane and the position and the size of roentgenogram launched field its calculating can realize through the mode of frame for movement, circuit or software by the focus of X ray.
