Project Abstract

Radiation Dose Optimization in Computed Tomography Imaging This project aims to address the critical issue of radiation dose optimization in computed tomography (CT) imaging, a widely used diagnostic tool that has revolutionized the field of medicine. As the use of CT scans continues to increase globally, there is a growing concern about the potential health risks associated with the ionizing radiation exposure, particularly in frequent and repeated examinations. This project seeks to develop innovative strategies and techniques to optimize radiation doses while maintaining the high-quality diagnostic information necessary for effective patient care. The primary objective of this project is to investigate and implement novel approaches to radiation dose reduction in CT imaging without compromising image quality or diagnostic accuracy. This is particularly important for vulnerable patient populations, such as children and pregnant women, who are more susceptible to the deleterious effects of ionizing radiation. By addressing this critical challenge, the project aims to enhance the safety and efficacy of CT imaging, ultimately leading to improved patient outcomes and reduced long-term health risks. The project will employ a multifaceted approach, integrating advanced imaging algorithms, hardware optimization, and comprehensive patient-specific dose assessment. It will explore the use of iterative reconstruction techniques, model-based iterative reconstruction (MBIR), and deep learning-based methods to enhance image quality while reducing radiation exposure. Additionally, the project will investigate the optimization of CT scanner parameters, such as tube voltage, current, and collimation, to achieve the desired balance between image quality and radiation dose. A key aspect of the project will be the development of comprehensive patient-specific dose assessment protocols. This will involve the use of Monte Carlo simulations, anthropomorphic phantoms, and patient-specific anatomical models to accurately estimate the radiation dose received by individual patients during CT examinations. By incorporating this information into the optimization process, the project aims to tailor the imaging protocols to each patient's unique characteristics, further minimizing the radiation burden. The research team will collaborate with clinicians, medical physicists, and radiation protection experts to ensure that the proposed solutions are clinically relevant, feasible, and compliant with established radiation safety guidelines. The project will also involve the validation of the developed techniques through rigorous experimental and clinical trials, ensuring the reliability and reproducibility of the results. The successful completion of this project will have far-reaching implications for the healthcare industry and the well-being of patients worldwide. By optimizing radiation doses in CT imaging, the project will contribute to the reduction of long-term health risks associated with ionizing radiation exposure, potentially leading to decreased incidence of radiation-induced cancers and other adverse effects. Additionally, the project's findings may be applicable to other medical imaging modalities, further expanding the impact on patient safety and the overall quality of healthcare. In conclusion, this project represents a crucial step forward in the quest to enhance the safety and effectiveness of CT imaging. By developing innovative strategies for radiation dose optimization, the project has the potential to transform the field of diagnostic imaging, ultimately benefiting patients, healthcare providers, and the global community.
