Application value of multi-row spiral CT and multi-slice spiral CT

Objective To discuss the structure function of multi-slice spiral CT for further enhancement of its application value. Methods The research is carried out through such aspects as the machine structure, image reconstruction method, scanning function, equipment self-restraint function of 16 slices multi-row spiral CT. Results With CT image resolution improved, spurious shade reduced and radiation dose dropped, the whole image quality enhances greatly. Conclusion In the using process of MSCT, different selection of slice thickness and detectors as well as the application of different image reconstruction methods in correct and reasonable using of CT technology will enrich clinical image information and further consummate the MSCT equipment functionality.
