Problems solved by technology

[0006] However, among the various methods of prolonging the life of CT tubes that have been provided at home and abroad, there is generally no obvious increase in the life of CT tubes. Especially in the case of high-heat capacity CT tubes, the life of CT tubes is generally low, resulting in the need for frequent replacement. Capacity CT tube, resulting in a huge waste of resources and a sharp increase in the cost of patients using CT equipment

Abstract

The invention relates to a method for prolonging the life of a CT tube, belonging to the technical field of medical materials. The method is characterized in that the performance of the rotating anodetarget and the shell, which are the key parts on the CT spherical tube, is improved, the shell is made of high-strength glass, and on the upper surface of the rotating anode target, a laser claddingmethod is adopted to clad the shell with a thickness of 0.5-0.8 mm in thickness, and the high temperature resistant coating is cladded on the transition layer. The alloy powder of the high temperatureresistant coating is prepared from 70-72% hafnium carbide powder, 26-28% tungsten powder, 1.0-1.2% Ce2O3 powder and 0.8-1.0% Y2O5 powder, and the thickness of the high temperature resistant coating is 1.5-1.8mm. The technology for preparing the 7-10 MHU CT tube with high heat capacity can prolong the life of a CT tube by more than 120%. The method has good economic and social benefits to popularize and apply.

Description

technical field [0001] The invention discloses a method for extending the life of a tube, in particular to a method for extending the life of a CT tube, and belongs to the technical field of medical materials. Background technique [0002] Due to the rapid development of modern computers, the development of modern medicine has also been promoted. Large-scale medical equipment such as computed tomography equipment (CT) has developed from conventional photography to brain scanning and cardiovascular angiography, from single-layer to spiral multi-layer. The importance of the tube as an X-ray source can be imagined. Multi-slice spiral CT scans continuously without interruption, and the X-ray dose is large, so the CT tube is required to have a higher heat capacity. The improvement of heat capacity requires continuous improvement and improvement of the tube material and the structure of the rotating anode. At present, the standard configuration of multi-layer spiral CT tube has ...
