Abstract:
As the number of CT scans continues to rise, the contribution rate of CT to the cumulative radiation dose to the public has exceeded 60%. During CT scanning, a shorter distance to the surface of the human body result in a higher radiation dose. Both the development of new CT imaging techniques and the selection of scanning parameters influence the dosage to superficial radiosensitive organs (e.g., eye lens, thyroid, and mammary glands). Effectively reducing the radiation dose to superficial radiosensitive organs has emerged as a hot research topic. This review aims to summarize the factors influencing the radiation dose to superficial radiosensitive organs and the dose reduction strategies, thus providing a reference for clinical practice and research on dose optimization.
