X-ray machine

Abstract

The invention relates to an X-ray machine. The X-ray machine comprises an X-ray bulb tube, an X-ray detector, a C arm and an adjusting arm. Two opposite ends of the C-arm are connected with the X-raybulb tube and the X-ray detector respectively. The center of the C arm deviates from a central beam of an X-ray beam. The C arm can rotate circumferentially between a first position and a second position around its center. The adjusting arm is connected with the C arm, drives the C arm to move axially and moves axially between a third position and a fourth position. The X-ray machine has the advantages that when the C arm is located at the first position and the adjusting arm is located at the third position, the intersection point between the central beam of the X-ray beam and the axis of theadjusting arm coincides with a locating position, and the distance between the locating point and the X-ray detector is constantly a specific value only by switching the adjusting arm between the third position and the fourth position after the C arm is switched from the first position to the second position or from the second position to the first position, so that control efficiency of the C arm is improved.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to an X-ray machine. Background technique [0002] At present, there are two designs of X-ray machines in the market, one is the C-arm isocentric design, that is: the center of the C-arm is located on the central beam of the X-ray beam between the X-ray tube and the X-ray detector, but This is not easy to ensure the balance of the center of gravity of the C-arm, and the control experience is not ideal. The other is the C-arm non-isocentric design, that is, the center of the C-arm deviates from the central beam of the X-ray beam between the X-ray tube and the X-ray detector. This design can achieve a good balance of the center of gravity and control The experience is better, but during the operation, especially when the front and side are switched, the image area of ​​interest may deviate from the X-ray irradiation range, and the image area of ​​interest needs to be posit...

The other is the C-arm non-isocentric design, that is, the center of the C-arm deviates from the central beam of the X-ray beam between the X-ray tube and the X-ray detector. This design can achieve a good balance of the center of gravity and control The experience is better, but during the operation, especially when the positive and lateral views are switched, the image area of ​​interest may deviate from the X-ray irradiation range, and the image area of ​​interest needs to be positioned repeatedly, which increases the radiation dose and reduces the manipulation efficiency
