Abstract
The invention discloses application of an image superposition technology to the detection of density values of bone minerals. The technical fields that the application of the image superposition technology to the detection of the density values of the bone minerals belongs to are medical instrument technologies and equipment and special medical software. The invention aims to solve the problems that: video recording is used for superposing images of detected parts of human bodies so as to increase gray scale, reduce video noise and effectively improve data accuracy. The implementation process comprises the following steps of: 1, performing high-speed video recording on a received image for 10 seconds by a high-speed camera which is controlled by a computer, and receiving by the computer; 2, decomposing and converting a video into 256 image files when the video is received; and 3, superposing the 256 image files to form a final image which inhibits noise and other interferences and improves grey level resolution, reading related bone absorption ray data after the image is subjected to data separation of interesting areas, and performing next data analysis and processing. Control programs and data processing programs of all equipment are written by using a C++BUILDER language.
Description
Technical field Medical Instruments technology, equipment and medical science special-purpose software
Background technology is utilized the X-ray imaging technique in the bmd analyzer, to the human body limb shooting of recording a video, carry out data analysis then.When in this technology the area-of-interest in the image being carried out data analysis, owing to be subjected to the restriction of detection figure image point greyscale resolution, video noise and circuit interference can have a strong impact on the data analysis result.Learn that by looking into newly analyze in the device of human body limb image at same utilization X-ray imaging technique, neither one is not adopt the method for image superposition to carry out date processing at present.
Technical problem to be solved: the present invention relates to use videotaping, the image at human detection position is carried out the image superposition, in order to increase tonal gradation, to reach the purpose that reduces video noise and effectively improve data precision.
Summary of the invention the present invention is applied to the bmd analyzer that my company develops with visual superimposingtechnique and carries out the bone density DATA REASONING, adopt videotaping in the measurement, image to the human detection position carries out the image superposition, in order to increase tonal gradation, reduce video noise and effectively improve data precision.Learn by looking into newly, still find no similar technology at present both at home and abroad.
Implementation process is:
1, records to receiving 10 seconds high speed of image realization by the high rapid fire picture of computer control head, receive by computer;
2, in video reception, video is carried out decomposition transform and become several image files;
3, several image files are carried out superposition and handle final image of formation, this image has suppressed noise and other interferential influence, and has improved gray level resolution.This image is carried out reading relevant bone resorption ray data after the region of interest data separating, carry out next step data analysis and handle.
The control of armamentarium and date processing use the establishment of C++BUILDER language.
The present invention has following characteristics:
1. high-speed camera, the video signal image that X-ray is accepted strengthens the high-speed photography of back use photographic head, collect a large amount of effective information of patient's limbs in short time at the utmost point, reduced the time that operating time and patient are subjected to x radiation x, the complexity of the X-ray discharger that uses and the energy intensity of release have been reduced simultaneously, reduce cost, strengthened safety.
2. utilize videotaping, the image of recording is carried out the video superposition, increase tonal gradation greatly, reduce video noise, effectively improved data precision and image definition.
3. video separation is separated the bone density effective information from captured video, carries out date processing by computer, and the result is shown more intuitively, has reduced doctor's working strength.

As Fig. 1: bmd analyzer outside drawing
This device mainly is made up of discharger, preventer, receiving system and computer system four parts.
Discharger comprises 13-low-voltage power supply, 14-X light emission unthreaded hole, 15-X light pipe emitter, 16-high-voltage power apparatus; Preventer comprises 2-guard shield plate, the plumbous road of 10-, 11-guard shield cover; Receiving system comprises that 3-photographic head connection cord, 4-photographic head, 5-image amplifier, 6-receive the presentation card of panel, 17-computer connection panel and main frame inside; Computer system comprises main frame, display, printer etc.
Limbs are put on the pallet 8, the device for opening power supply, the high-voltage power apparatus 16 in the discharger discharges the 70000V high pressure, drive X-ray tube emitter 15 and send X ray, the ray that sends from X-ray emission unthreaded hole 14 passes through plumbous road 10, passes light-passing board 9 and limbs, arrives receiving system.Be in receiving system image amplifier 5 foremost and receive X ray, photographic head 4 can be filmed the X ray that receives afterwards, be transferred to computer by photographic head connection cord 3 and connect panel 17, be transferred to the presentation card that is installed in the main frame through this panel again, handle through presentation card, captured image is transferred to computer system, carries out the analysis and the processing of videotaping, video separation, image superposition and follow-up pictorial data by computer.
