The utility model relates to an X-ray non-film computer imaging device, composed of an X-ray generator, a combined dark room, and a microcomputer. The utility model is characterized in that the combined dark room is composed of an X-ray intensifying screen, lead glass, an optical coupling lens, a high-sensitivity CCD video camera, and a dark room casing. The window of the dark room is provided with the X-ray intensifying screen and the lead glass; the high-sensitivity CCD video camera is arranged on the other end of the dark room; the optical coupling lens is arranged on the camera head of the high-sensitivity CCD video camera whose video output end is connected with the microcomputer. The utility model which can work in a bright room has the advantages of easy operation, no irradiation of X-ray, and X-ray image required real time and rapid display.

Description

The X line does not have film computer generated image device

The utility model relates to medical treatment control diagnostic instrments, and especially a kind of X line does not have film computer generated image device.

At present, be used for the X line instrument of medical diagnosis, generally only have following two kinds of functions, first perspective, another then is film making.Its defective of various degrees all again separately of these two kinds of functions.For first kind, its major defect is that operating personnel must be at dark room operation, and is nearer from the x-ray generator position, can be subjected to the x-ray radiation of doses, harmful to operating personnel; For a kind of function in back, its adopts is the mode of developing a film after traditional the taking pictures, it can't realize real-time demonstration, how are the effect after an X line film can't be known bat when taking so on the one hand and the degree of exposure, in case of emergency can not take the X-ray sheet that just takes and be badly in need of on the other hand at once; Other traditional X-ray film takes and wash picture apparatus expensive, process complexity and X-ray film is easy to break, easily broken, be difficult for preservation, not portable.And in order to overcome the shortcoming that realizes above two kinds of function X line instrument, high-grade X line instrument has increased video and has strengthened equipment.But this equipment not only cost is extremely expensive, and has limited to the camera photography scope.

The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, proposes a kind ofly can make operating personnel avoid x-ray radiation, and can be in real time, make things convenient for, show required X light image quickly, X line with low cost does not have film computer generated image device.

Goal of the invention of the present utility model is not have film computer generated image device by a kind of X line that following scheme realizes, by x-ray generator, combination darkroom and microcomputer are formed, it is characterized in that described combination darkroom is by X line intensifying screen, lead glass, optical coupling lens, high-sensitive CCD video camera and darkroom housing are formed, the end that the darkroom housing is relative with x-ray generator has window, outside in overlapping successively X line intensifying screen and the lead glass of being equipped with at the window place, high-sensitive CCD position for video camera other end in the darkroom, optical coupling lens is positioned at the camera place of high-sensitive CCD video camera, and the video output terminals of high-sensitive CCD video camera links to each other with microcomputer.

In such scheme, can add graphics acceleration card and video frequency collection card on the described microcomputer.

Principle of work of the present utility model is, x-ray generator sends the X line and sees through the measured and need inspection area, forms X line video on X line sensor screen, and the CCD to high sensitivity takes the photograph on the illiteracy machine image planes through optical coupled, gives main frame by the vision signal of gamma camera outputting standard again.So just avoid the use of expensive video intensifier, and can realize any conversion in the visual field, the restriction of no scope simultaneously.And this point to be achieved be to depend on modern highly sensitive charge coupled device ccd gamma camera, it can be in dark room conditions under low-light (level), the X light image that clear view is manifested to X line sensor screen.Microcomputer installs graphics acceleration card and video frequency collection card additional.Its course of work is the vision signal that the CCD gamma camera transmits, be converted to digital signal after the video frequency collection card collection in the microcomputer, quicken by graphics acceleration card, optimize on input signal and the microcomputer monitor and show, adjust to optimum condition then, moment takes in real time, the image digital signal that gets this moment is deposited in the hard disk of microcomputer so that next step image processing again.The image of handling well is given and is mixed the Word message (also can add acoustic information as needs) that is associated, can output to laser printer on the one hand depicts clearly X light image or copy and goes into floppy disk and retain to patient, also can be input on the hospital computer server and stay shelves, so that call, check for the user on each terminal.

The utility model mainly has following advantage: operating personnel work in bright chamber, easy operating and be not subjected to x-ray radiation.Because what take is to show in real time and shooting, can see required X light image quickly and easily at once.And image and patient history and diagnosis book can be attached to and be stored in together in the computing machine, and through software control, Chinese interface can be preserved easily, calls, optimize and be convenient to check.Thereby letter the diagnostic procedure of in the past making film, saves a large amount of films, reduced numerous and diverse flushing device and process, and can win a large amount of time, convenient prescription on individual diagnosis.In addition owing to do not adopt original video enhanced system, but be assurance with highly sensitive CCD gamma camera and graphics acceleration card, not only can obtain picture more clearly, and enlarged see-through area (being subjected to video to strengthen the control of instrument size) with forward view, and saved fund, reduced cost.

Concrete structure of the present utility model is provided by the following drawings illustrated embodiment.

Fig. 1 is the utility model fundamental diagram.

Fig. 2 is a combination darkroom structural representation.

With reference to accompanying drawing, the utility model mainly is made up of x-ray generator 1, combination darkroom 2, microcomputer 6 and image recorder 10.Wherein, combination darkroom 2 is made up of high-sensitive CCD video camera 5, optical coupling lens 4, X line intensifying screen 3 and lead glass 14 and darkroom housing 15.Have unlimited window 16 at darkroom housing 15 towards an end of x-ray generator 1, outside in overlapping successively window 16 places that are fixed on of X line intensifying screen 3 and lead glass 14, the other end is equipped with high-sensitive CCD video camera 5 by camera mount 18 in the darkroom, optical coupling lens 4 is contained in the camera place of video camera, and a glass 17 is housed in the middle of the darkroom.Scribble pitch-dark on the inwall of darkroom.The video output of high-sensitive CCD video camera 5 links to each other with microcomputer.Video frequency collection card 7 and graphics acceleration card 8 are housed on the microcomputer 6, and microcomputer 6 links to each other with hospital computer server 9 with image recorder 10.Image recorder 10 comprises laser printer 11 and floppy disk 12.

The utility model is to radiate the X line by x-ray generator 1 to see through human body, obtain required detection position visible light image on lead glass 14, after optical coupling lens 4 optical coupled, taken in by CCD gamma camera 5, take in the back and be about to the photosignal conversion for vision signal, vision signal input microcomputer 6, gathered and conversion of signals by video frequency collection card 7 wherein, the digital signal that conversion is come out is accelerated by graphics acceleration card 8 and optimizes, and everything is controlled by microcomputer 6 by operating personnel.May command image recorder 10 comprises laser printer 11 and floppy disk 12 output images in addition, and also may command is transported on the hospital computer server 9 and filed, so that called, check by each terminal 13.
