Abstract
The utility model discloses a tube/detector synchronous linkage scanning device which comprises a rotary X-ray tube, a detector and a linkage device pushed by the detector to rotate in synchronization with the X-ray tube, wherein the rotary X-ray tube and the detector are connected through the linkage device. The utility model can achieve the purpose of imaging by taking full advantage of the most uniform part of X-ray beams from the X-ray tube.
Description
Technical field
This utility model relates to a kind of device that human body mammary gland is detected, and is a kind of medical apparatus and instruments concretely.
Background technology
Please refer to Fig. 1; Bulb and detector synchronous interaction scanning means generally all are to adopt the X ray tube fixed to the scanning detection of breast at present; The X ray that penetrates from bulb arrives the mode of below platform for video camera photographic imagery, such as adopting film or dull and stereotyped CCD digital camera mode.
Adopt the mode complex operation of film imaging, and can not carry out software processes to image, make image reach an ideal resolution, in addition, conventional film reading mode can not provide the remote image consultation of doctors and propose the remote image diagnosis report.
Adopt dull and stereotyped CCD digital photography mode can't utilize the position imaging the most uniformly of bulb X-ray bundle to greatest extent, thereby cause the distortion of image easily, and can't control the dosage and the scope of X-ray to greatest extent, bigger to person under inspection's radiation.
The utility model content
The purpose of this utility model provides a kind of bulb and detector synchronous interaction scanning means, solves technical problem how to utilize position imaging the most uniformly of bulb X-ray bundle and low dosage to greatest extent.
Bulb and detector synchronous interaction scanning means comprise rotatable X ray tube, detector, are promoted and then make the bulb linkage of rotation synchronously by detector; Rotatable X ray tube is connected through linkage with detector.
Said detector comprises slit light concentrator, planar array scanning imageing sensor; The slit light concentrator is located at X ray tube below, can be located under the slit light concentrator at the planar array scanning imageing sensor that moves on the linkage, and linkage is located between planar array scanning imageing sensor and the X ray tube.
Said bulb and detector synchronous interaction scanning means also are provided with a rotating shaft, and this rotating shaft and X ray tube are fixedly connected and are located at the center of focus of X ray tube.
Said linkage comprises line slideway and connecting rod; The planar array scanning imageing sensor is located at and keeps on the line slideway being slidingly connected with it; The planar array scanning imageing sensor other end is connected with connecting rod one end horizontal slip, and the other end of connecting rod then is connected with the rotating shaft of X ray tube.
Described planar array scanning imageing sensor is the area array CCD imaging device.
Said slit light concentrator has the strip opening.
The beneficial effect of this utility model is,
1. owing to adopted bulb synchronous scanning; So just can utilize to greatest extent bulb the most uniformly the X-ray bundle come scanning imagery, thereby improve picture quality, the uniformity etc.; Helping the doctor diagnoses more accurately; This technology can use the low-angle bulb to realize large-area exposure image simultaneously, practices thrift cost, improves the probability that product is popularized.Light concentrator can be regulated slit according to the big I of the pick off of scanning imagery, and unnecessary X line utilizes the shade line material that unwanted ray is shielded.The scanning that can be synchronized with the movement of pick off and X ray tube can make image resolution ratio higher, has reduced the dosage of X ray simultaneously to greatest extent.Traditional imaging mode is to keep bulb to fix, and utilizes slit to scan, thus the image that forms, and this technology can't reach low dosage, high-resolution.
2. owing to adopted the matrix CCD scanning technique, changed the dull and stereotyped technique for taking of traditional face battle array, improved the resolution of image, reduced x-ray dose, reducing cost simultaneously helps popularizing of digital galactophore camera chain.

The specific embodiment
Please refer to Fig. 2 to Fig. 4, the bulb of present embodiment and detector synchronous interaction scanning means include X ray tube 1, slit light concentrator 2, area array CCD imaging device 3, line slideway 4, connecting rod 5; Slit light concentrator 2 adopts screw or alternate manner to be fixed on X ray tube 1 below, and centrally aligned x-ray focus 6.This slit light concentrator 2 sees through its strip opening at X, Z-direction and only stays the light in the slit 7 described in the X-ray bundle is promptly schemed the most uniformly, and all the other are then all covered.Area array CCD imaging device 3 be provided with can be on line slideway 4 mechanism of level run, connecting rod 5 can drive X ray tube 1 and rotate when 3 motions of area array CCD imaging device.
Light penetrates from x-ray focus 6 and passes slit light concentrator 2 and arrive area array CCD imaging devices 3 and form single cross sectional images, area array CCD imaging device 3 is moved on line slideway 4 and then can obtain the image at all positions of whole person under inspection.
