摘要

Understanding the physics behind CT imaging is fundamental and a heavily tested topic. An understanding of the physics serves not just in troubleshooting CT images, but in their very interpretation. This chapter serves to explain fundamental physics principles in CT image acquisition and reconstruction, with some topics revisited in further detail in later chapters.
