Embodiment Construction

[0022] The implementation of the receiving location changing platform of the present invention will be described in detail below.

[0023] The reason why X-ray imaging can make the human body form an image on the screen or film is based on the characteristics of X-rays, that is, its penetrability, fluorescence effect and photographic effect; on the other hand, it is based on the difference in density and thickness of human tissue. . Due to this difference, when X-rays pass through different tissue structures of the human body, they are absorbed in different degrees, so the amount of X-rays reaching the screen or film is different. In this way, images with different black and white contrasts are formed on the screen or X-ray.

[0024] The formation of X-ray imaging should meet the following three basic conditions: first, X-rays should have a certain penetrating power, so as to penetrate the irradiated tissue structure; second, the penetrated tissue structure must have density ...

Abstract

The invention relates to a receiving position change platform which comprises an unwinding motor, an unwinding roller, a fixed pulley, a winding roller, a signal triggering device and a displacement driving device. The unwinding motor is arranged in a conveying structure, the output power of the unwinding motor is 2 kilowatts and is provided with a rotating spindle, the diameter of the rotating spindle is 200 millimeters, the winding roller is arranged in the conveying structure and connected with the rotating spindle through a conveying belt, the diameter of the winding roller is 360 millimeters, the fixed pulley is arranged in the conveying structure and used for receiving the conveying belt conveyed by the unwinding roller and sequentially transmitting the conveying belt to the windingroller, the winding roller is arranged in the conveying structure and connected with the fixed pulley through the conveying belt, the diameter of the winding roller is 360 millimeters, the output power of a winding motor of the winding roller is 5.5 kilowatts, the signal triggering device is used for transmitting a first driving signal when the real-time signal to noise ratio exceeds a limit, otherwise, the signal triggering device transmits a second driving signal, and the displacement driving device is used for adjusting X-ray receiving position of an X-ray imaging mechanism when the first driving signal is received. By the aid of the receiving position change platform, and the X-ray receiving position is effectively calibrated.

Description

technical field [0001] The invention relates to the field of X imaging, in particular to a receiving position changing platform. Background technique [0002] X-ray imaging is a new type of medical examination method that combines image enhancement technology, television technology and computer technology with conventional X-ray angiography. The commonly used digital X-ray imaging methods in clinical practice include digital subtraction angiography and X-ray computer imaging. and digital imaging, etc. Contents of the invention [0003] In order to solve the technical problem that the X imaging mechanism and the X-ray source lack a high-precision relative setting and calibration mechanism in the prior art, the present invention provides a receiving position change platform. [0004] For this reason, the present invention needs to have the following two key invention points: (1) In order to ensure that the X-ray imaging mechanism can be arranged opposite to the X-ray source...
