Description

X-ray double parallax stereo-perspective apparatus and formation method

The present invention relates to a kind of new X-actinoscopy X machinery equipment.

The common practice is with x-ray irradiation people object when seeking and visiting people's object internal information, because the X-ray is to the see-through capabilities difference of different material, the X-ray institute excited fluorescent contrastographic picture of having an X-rayed like this on the fluorescent screen is also different, therefore, operating personnel can judge its inner case according to the inner contrastographic picture information of the light and shade personage on the screen.

Present X-actinoscopy X equipment generally can only obtain plane picture on a screen, owing to there is not third dimension, operating personnel can only rule of thumb judge the about locus and the situation of change of personage's internal information radiography, judge that sometimes very big difficulty will take place interior details.

The objective of the invention is to provide a kind of X-ray double parallax stereo-perspective apparatus and formation method, it can make operating personnel obtain to be penetrated the perspective interior view picture of people's object, thereby accurately, be well understood to interior details and situation of change.

The object of the present invention is achieved like this: the X-ray double parallax stereo-perspective apparatus mainly contains two X-ray light sources, a stereotype masked wide-screen film is arranged before, can only allow the X-beam of a certain light source pass through during rotation at every turn, arrive fluorescent screen behind the transmission people object, the fluorescence excitation material forms a secondary flat according to image.Subsequently, masked wide-screen film Rotate 180 °, the X-beam of another light source be by masked wide-screen film, forms another width of cloth dystopy plane on the phosphor screen according to image arriving when the picture drop-out first time.Continue like this, will occur two width of cloth potential difference image, i.e. the double vision difference images that replace at a high speed on the phosphor screen.As long as the operator puts on the double vision difference visor synchronous with the stereotype masked wide-screen film, make every width of cloth image visually produce stereo-picture naturally, just can in the spatial dimension between screen and the visor, see comprehensive details and situation of change in well-bedded people's object.

The present invention is owing to only increase by a light source on common X-actinoscopy X machine, the synchronous visor of electrically-controlled liquid crystal double vision difference that stereotype cropping mechanism and operator wear, and structure is also uncomplicated, realizes that easily use cost is not high.Because the opening on the stereotype masked wide-screen film can only allow the X-beam of a certain light source pass through at every turn, certain anglec of rotation is arranged, intermittent time shines the exposure that the interior X-quantity of X-rays X of people's object is less than common X-actinoscopy X machine like this, will be more useful to human beings'health.

Concrete grammar of the present invention and structure are provided by following embodiment and accompanying drawing.

Fig. 1 is the structure chart according to the X-ray double parallax stereo-perspective apparatus of the present invention's proposition.

Describe the details and the working condition of this machinery equipment and formation method in detail below in conjunction with accompanying drawing.This machine comprises two X-ray light sources (1) and (4) arranged side by side, normal separation is 65mm, a rotary stereotype masked wide-screen film (5) is arranged before, there is motor (3) to drive, link with synchronous signal of telecommunication control switch (2), (6) are had an X-rayed people's object, and (7) are fluorescent screens, right eyeglass (8) of the double vision difference visor that operating personnel wear and left eyeglass (9) reach part compositions such as synchronizing signal pilot (10).(less important part such as support do not draw among the figure such as circuit).

When X-ray light source (1) and (4) work, stereotype masked wide-screen film (5) is driven by motor (3) and begins rotation, owing to have breach on the stereotype masked wide-screen film (5) less than 1/2 area, can only allow the X-beam of some light sources pass through at every turn, and the X-beam of another light source is limited to the transmission capacity of stereotype, so lived by shelves.When masked wide-screen film (5) opening part is facing to light source (1) like this, the X-beam of this light source can pass through, perspective people's object (8), be mapped on the fluorescent screen (7) fluorescent material stimulated luminescence, the light and shade contrastographic picture of the once illuminated people's object of formation, double vision difference visor sheet (8) is received the signal of telecommunication that synchronous cropping signaling switch is sent by lead (10) simultaneously, the beginning shading, and eyeglass (9) printing opacity makes operator's left eye obtain a plane picture information.Subsequently, masked wide-screen film (5) Rotate 180 °, the X-beam of light source (4) is passed through, transmission people object when the first time, the image radiography disappeared, arrives fluorescent screen (7) and produces the new poor bit image information of another width of cloth, this moment, double vision difference visor was received the signal of telecommunication, eyeglass (9) matte, eyeglass (8) beginning printing opacity, right eye obtains a potential difference plane picture information.Two eyes are in the extremely short time, and difference is opened 1/12-1/100 time second and obtained image information separately respectively, just as having seen two plane pictures of same object, and just generation stereo-picture naturally visually.Though two width of cloth images are branch poor opening successively, the difference ETAD expected time of arrival and departure is extremely short, and human eye can't be discovered; The cropping of stereotype masked wide-screen film (5) and double vision difference visor sheet (8) (9), shading and printing opacity frequency just can obtain continuous third dimension within per second 12-100 underrange, as obtaining the flicker free sensation at 50 or 100 times/second, omnidirectional three-dimensional stereo-picture, human body especially as transparent jellyfish, between screen (7) and double vision difference eyeglass in the area of space, life-like, well arranged, internal's profile, variations in detail, the position is high-visible, the resolution height.

In order to enlarge amount of image information, X-ray source (1) (2) spacing, angle, irradiation positions etc. can arbitrarily be adjusted (not drawing among the figure) by a controlling organization.The structure of double vision difference visor sheet (8) (9) can be by automatically controlled, the mode of liquid crystal molecule rotation shading is finished, its principle is similar in appearance to the brilliant shading welding helmet of Japanese production fluid eyeglass, also can be by mechanical system, remote control is finished, but must be not printing opacities (being different from any in the world glasses with this) simultaneously of two eyeglasses.Two X-ray sources (1) (4) of this device also can adopt alternately emission strong, and the mode of weak X-ray can be saved the cropping part like this, and each light source is synchronoused working with parallax visor sheet (8) and (9) and got final product, and this mode is fairly simple.Effectively same.

The double parallax stereo imaging method that the present invention relates to is applicable to all visible lights and invisible ray and excusing from death ripple, electron beam etc., the contrastographic picture that excites by fluorescent material.The advantage of this method is after two-way is represented poor in time the opening of information of three-dimensional image, to merge into one the tunnel.(only showing the two-way image with a phosphor screen as the present invention) is so available existing single cover video equipment absorbs, propagates, writes down, stores the three-dimensional image information that this method obtains.Present stage can be used the screen cylindrical lens, perhaps reproduces with double vision difference visor, and the form of free space reflection is reproduced in the future.
