Description

Technical Field

[0001] The utility model relates to the relevant technical fields such as X-ray photography auxiliary devices, and in particular to a standing position X-ray photography frame. Background Art

[0002] X-ray photography is one of the commonly used medical examination methods, which is used to observe the position, shape and density difference of internal organs and tissues in the body. Experienced diagnostic physicians find abnormalities in the images generated by X-ray photography and then make a diagnosis of the disease. The common body position for X-ray photography is standing. When shooting in the standing position, the patient needs to be positioned twice in the front and side positions under the guidance of the operating technician to make the photography position standardized and the image clear. However, conventional X-ray photography is a non-quantitative examination. The position on the image has a magnification effect and is a relative value, which reduces the utilization value of X-ray photography to a certain extent. In theory, through the principle of binocular vision, the spatial position of an object can be obtained by observing at a certain angle, such as shooting twice in the front and side positions. This requires that the object remains stationary in relative spatial position during the two shots. In conventional standing X-ray photography, the patient's body position moves greatly during the two positions, with low regularity, and it is difficult to achieve relative stillness in spatial position.
