Abstract

The invention discloses a detection method of a phosphor powder sizing agent for an intensifier output screen. The concentration of the phosphor powder sizing agent to be detected is firstly detected,the phosphor powder sizing agent with a concentration range of 10-14mg / L is selected, then particle granularity and granularity distribution of the selected phosphor powder sizing agent are detected,and the phosphor powder sizing agent with the particle diameter concentrated at 2-4[mu]m is selected. According to the detection method of the phosphor powder sizing agent for the intensifier outputscreen, operation is simple and easy, the detection speed is high, the efficiency is high, the yield of the intensifier output screen is improved, material wasting is avoided, the cost is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of luminescent materials, in particular to a method for detecting fluorescent powder slurry for an output screen of an intensifier. Background technique [0002] Due to the advantages of low cost, convenient operation and good compatibility, computed radiography (CR) technology has broad application prospects in medical diagnosis and disease treatment. [0003] The image intensifier in the X-ray photography system is an essential component. After the X-ray passes through the PCB board, the image intensifier is used to receive and intensify the image, and finally the image information on the image intensifier is extracted by the CCD camera and handed over to the computer for processing; The X-ray image intensifier is a vacuum imaging device, which is composed of a photoelectric conversion screen, a photocathode assembly, an electron optical focusing system and an output fluorescent screen. The X-ray image of ...
