A key physics concept in CT imaging is the understanding of radiation. CT uses x-ray radiation for image acquisition, which has both stochastic and deterministic adverse effects. This chapter focuses on measuring and standardizing radiation dose, integrating methods to reduce total radiation. Understanding radiation principles allows for using the lowest radiation dose while optimizing image quality.

A key physics concept in CT imaging is the understanding of radiation. CT uses x-ray radiation for image acquisition, which has both stochastic and deterministic adverse effects. This chapter focuses on measuring and standardizing radiation dose, integrating methods to reduce total radiation. Understanding radiation principles allows for using the lowest radiation dose while optimizing image quality.
