Özet

Computed tomography has become a crucial diagnostic method in a wide range of medical practices, such as cancer detection and management. However, the overuse of X-ray radiation poses a danger of cancer induction. The global spread of CT use in recent years has been accompanied by a growing awareness of the link between high-dose radiation exposure and cancer development. In response to these concerns, the global CT manufacturers have introduced many low-dose radiation techniques in CT scans to minimize radiation exposure without affecting the image quality. This paper’s objective is to demonstrate these techniques’ capabilities of reduction doses enormously and explain every CT manufacturer’s special approach. For this study, the literature was extensively searched, and all techniques presented by each CT manufacturer were demonstrated. Also, an explanation of AI applications and photon-counting detectors was discussed as a future aspect of the new low-dose reduction method. These advancements in CT technology not only represented the cutting edge of technology, but also demonstrated a dedication to constantly increasing patient safety and diagnostic accuracy in medical imaging.
