In this paper, X-ray film method and real-time imaging method to detect the limitations of solid-state engines are introduced. The solid-state engine CT system with excellent flaw detection performance is introduced. The principle of system-generated image of thin-section density distribution of the engine is briefly introduced and described. Like the reconstruction method, the basic components of the system and the key components, the capability of the system to detect the performance of solid-state engines and the detection of various defects are reviewed and their advantages and disadvantages are discussed. The recent trends of industrial solid-state engine CT systems are briefly described.
