Analysis And Research For CT Equipment Malfunction

As the CT value of an important clinical diagnosis,it has become indispensable in hospitals clinical diagnostic tools and research tools, and even spread to a number of township hospitals.CT as a result of the high usage rate, usually 24 hours works, so a higher failure rate, most hospitals lack the capacity of their own maintenance, the need for third-party manufacturers to repair or maintenance, high maintenance costs. CT machines are being used in both single-slice helical CT has the most advanced 64-row CT and the latest dual-source CT. Although performance varied widely ,the fault type the causes and finds is basically the same method. CT is composed of many parts of the system is very complex, involving computer technology, electronic technology, precision machinery and the latest automation technology. To ensure that theHospital's own engineering and technical personnel, increasing the difficulty of maintenance, many hospitals can only buy the warranty. Increase for hospitals and patients with a serious economic burden. The purpose of this paper is to explore the technology at home under the conditions of the existing CT equipment to the maintenance of technical and troubleshooting methods, in order to enable a more systematic and practical paper, the following arrangements for the paper.The main contents of the paper is as follows:Chapter I deals with the history of the development of CT and its important role, and an analysis of the status quo at home and abroad, research and trends, presented the contents of this paper, the purpose of significance.Chapter II describes the working principle of CT and system architecture. Start by describing the characteristics of the X-ray and material on the X-ray absorption, CT image reconstruction principle. And then into the internal equipment to examine each and every one of the main components, in particular the relationship between the various components, discusses the latest developments in CT equipment and equipment development.Chapter III to the use of CT in our hospital as an example, more than 10 years of breakdown by a comprehensive statistical analysis, and failure of the system components are classified, mainly from the theory by a detailed analysis of CT resulting from the cause of the malfunction. At the same time to analyze the working principle of combining the characteristics and patterns of failure, and a detailed analysis of these failures and propose solutions.Chapter IV summarizes the main developments in this paper, CT for future fault analysis study, should be noted that some of the issues and recommendations.
