Embodiment Construction

[0021] Please refer to Figure 1 to Figure 4 , the C-arm 8 of the present embodiment mainly rotates through two rotating shafts and two racks, these two rotating shafts are left and right rotating shafts 9 and pitching rotating shafts 10, and the two racks are rotating racks 11 and fixed Frame 12; the left and right rotation axis 9 drives the C arm 8 to rotate left and right, and the pitch rotation axis 10 drives the C arm 8 to perform a pitching motion, so that the C arm 8 of the mammography machine performs a three-dimensional motion of tilting forward and backward.

[0022] Please refer to Figure 3 to Figure 4 , the C arm 8 includes an X-ray tube 1, a slit beamer 2, an area array CCD imaging device 3, a linear guide rail 4, and a connecting rod 5; the slit beamer 2 is fixed on the X-ray ball by screws or other means below the tube 1 and centered on the x-ray focus 6. The slit beamer 2 passes through the elongated opening in the X and Z axis directions, leaving only the s...

Abstract

The invention discloses a mammary machine with a three-degree-of-freedom-of-motion C-shaped arm. The mammary machine comprises a frame, a C-shaped arm, a bulb tube and a detector, wherein one end of the C-shaped arm is connected with the bulb tube, and the other end of the C-shaped arm is connected with the detector; and the C-shaped arm is connected to the frame through a rotating shaft. By the mammary machine, the technical problems of difficulty in imaging by using the most uniform part of an X light beam of the bulb tube to the maximum extent in a low dose and difficulty in front-and-back inclined three-dimensional motion of the C-shaped arm can be solved. The mammary machine can be used as a medical instrument.

Description

technical field [0001] The invention relates to a device for detecting mammary glands, in particular to a medical device. Background technique [0002] Please refer to figure 1 At present, the tube and detector synchronous linkage scanning device generally uses the X-ray tube to be fixed, and the X-rays emitted from the tube reach the lower camera platform for photography and imaging, such as film or flat-panel CCD. digital camera. [0003] The operation of film imaging is cumbersome, and the image cannot be processed by software to achieve an ideal resolution. In addition, the conventional film reading method cannot provide remote image consultation and remote image diagnosis report. [0004] The flat-panel CCD digital photography method cannot maximize the use of the most uniform part of the tube X-ray beam for imaging, which easily causes image distortion, and cannot control the X-ray dose and range to the maximum extent, and the radiation to the subject is relatively l...
