Abstract
The utility model discloses a mammary radiography machine with a C-shaped arm and three degrees of freedom of motion. The mammary radiography machine comprises a framework, the C-shaped arm, a bulb tube and a detector. One end of the C-shaped arm is connected with the bulb tube, the other end of the C-shaped arm is connected with the detector, and the C-shaped arm is simultaneously connected onto the framework via a rotating shaft. The mammary radiography machine can realize that a portion, with the most uniform X light beam, of the bulb tube is used to the greatest extent and in the lowest dosage to realize imaging, and the C-shaped arm three-dimensionally moves obliquely back and forth. The mammary radiography machine can be used as a medical instrument.
Description
Technical field
This utility model relates to a kind of device that 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.
Traditional mammary gland machine C shape arm generally can only move up and down side-to-side movement.The position of being examined is limited to, can not realize the position shooting, undesirable to person under inspection's self comfort.
The utility model content
The purpose of this utility model provides a kind of C arm mammary gland machine with 3 freedoms of motion, how to solve to greatest extent and the utilizing the position imaging the most uniformly of bulb X-ray bundle and make the technical problem of the three-dimensional motion that mammary gland C shape arm tilts before and after doing of low dosage.
Have the C arm mammary gland machine of 3 freedoms of motion, comprise frame, C arm, bulb, detector; C arm one end connecting bulb, the other end connects detector, and this C arm is connected on the frame through rotating shaft simultaneously.
Said frame comprises fixed frame, rotary frame, left rotation and right rotation axle, pitching rotating shaft; Left rotation and right rotation axle one end is connected with the C arm, and the other end is connected with rotary frame; Pitching rotating shaft one end connects the opposite side of rotary frame, and the other end connects fixed frame.
Said bulb is rotatable X ray tube, and this X ray tube is through being fixedly connected the center of focus that is located at the X ray tube with rotating shaft.
Said detector comprises slit light concentrator, planar array scanning imageing sensor; The slit light concentrator is located at X ray tube below, and the planar array scanning imageing sensor is located under the slit light concentrator.
Also be provided with between said detector and the bulb by detector and promote and then make the bulb linkage of rotation synchronously; Rotatable X ray tube is connected through linkage with detector.
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 to form the 3rd freedom of motion when forming second freedom of motion, the rotation of pitching rotating shaft when forming first freedom of motion, the rotation of left rotation and right rotation axle during the rotation of X ray tube; X ray tube rotation the time forming first freedom of motion with utilize to greatest extent bulb the most uniformly the X-ray bundle come scanning imagery; Thereby raising picture quality; The uniformitys etc. help the doctor and diagnose more accurately, and this technology can use the low-angle bulb to realize large-area exposure image simultaneously; Practice thrift cost, improve the probability that product is popularized.Use left rotation and right rotation axle and pitching rotating shaft just can carry out the front and back banking motion and form three-dimensional motion; Just can under person under inspection's pitch attitude, better realize the three-dimensional imaging of mammary gland; Can help the doctor to carry out the focus location more accurately; Be the realization generaI investigation, biopsy, Minimally Invasive Surgery is integrated in early days provides the foundation.
