在仅有图像增强器而不具备数字图像处理单元的X射线工业电视系统上，进行各种工艺参数的实验优选，并采用选择小焦点射源、散射屏蔽等措施，提高系统检测灵敏度。实验证明：系统检测灵敏度可以调整提高到小于2％，使图像增强型X射线工业电视系统成功地应用于液化石油气钢瓶焊接生产线。
In the X-ray industrial television system which only has the image intensifier and does not have the digital image processing unit, experiments and optimization of various process parameters are carried out, and the detection sensitivity of the system is improved by selecting small focus sources and scattering shielding. Experiments show that the system detection sensitivity can be adjusted to less than 2%, so that the image enhanced X-ray industrial television system successfully applied to liquefied petroleum gas cylinder welding production line.
