Dual-source computed tomography(CT)has a series of functions such as rapid scanning,cardiac imaging,multi-site imaging and spectral imaging,and it has the advantages of high image quality and low radiation dose.The timely maintenance and repair can ensure the stable operation of equipment,and guarantee smooth progress of clinical examinations,and provide reliable basis for the diagnosis and treatment to patients.This paper sorted out and analyzed the mechanical structure about the SOMATOM Force CT equipment from three parts:operation and control,data acquisition,and processing and transmission.It also analyzed the correlation between the mechanical structure and functions around the key components such as X-ray tubes,detectors,collimators,slip rings and high-voltage generators,and clarified the role of each component in CT imaging.In general,this paper summarized the troubleshooting ideas and the key points of maintenance and repair for the mechanical faults of the SOMATOM Force CT scanning bed,cooling device and slip ring,which can accumulate the practical experience in improving the guarantee ability of engineers.
