手控可调四肢X线摄影辅助角度测量仪的设计

Design of A Manual Adjustable Angle Measuring Instrument Used in Radiography of Limbs

本文设计了一种手控可调四肢X线摄影辅助角度测量仪。该仪器设计主要为木质材料,其结构包括底板、两个相同的角度盘、内侧固定板、外侧固定板和测量板,可实现对人体四肢X线摄影过程中被检部位倾斜角度的测量、旋转角度的预置和体位的固定。该手控可调四肢X线摄影辅助角度测量仪不仅能减轻放射技术人员的工作量,也降低了被检者的检查配合难度,避免了多次曝光带来的额外潜在辐射伤害。

In this paper, a manual adjustable angle measuring instrument used in radiography of limbs was designed. The instrument was mainly made of wood. It was equipped with the bottom plate, two identical angle plates, the inner fixed plate, the outer fixed plate, and the measuring plate. The angle measuring instrument can realize the measurement of the tilt angle, preset of the rotation angle, and immobilization of the area examined during radiography of human limbs. The manual adjustable angle-measuring instrument can not only reduce the workload of radiology technicians, but also reduce the difficulty of examination coordination of subjects, and avoid additional potential radiation damage caused by multiple exposures.
