Low-dose computed tomography is increasingly used in in vivo clinical biomedical experiments. International radiation-protection bodies promote its use to reduce radiation exposure. The method involves using a lower dose of radiation while maintaining image quality. This approach is beneficial for patients and healthcare professionals alike. The use of low-dose computed tomography has several advantages, including reduced radiation exposure, improved image quality, and increased patient safety. It is essential to note that the optimal dose for low-dose computed tomography is still a topic of ongoing research and debate. Further studies are needed to determine the most effective dose for various applications.
