Correlation analysis of organ doses with dose metrics for patients undergoing organ dose-modulated head CT examinations. [PDF]
Quant Imaging Med SurgThe rapid advancement of computed tomography (CT) has greatly improved clinical diagnosis but has also introduced new challenges in radiation protection. This study aimed to evaluate the relationship between organ doses from Monte Carlo (MC) simulations and CT dose metrics for head CT exams with organ dose modulation (ODM), and to develop a simplified ...
