Book excerpt: The study consisted of taking radiation dose measurements on an adult male phantom and a 9-month-old male phantom during multiple types of CT scans, and replicating the same scans using the Monte Carlo method. The study found that for all CT scans for both phantoms, the results suggested excellent agreement between measured and simulated organ doses. For the adult male, the percent differences between simulated and measured organ doses for all scans were all within 15.5%. For the 9-month-old, the percent differences were all within 13.9%. These percent difference results were comparable to previous validation studies using anthropomorphic phantoms. Overall, the study validated the accuracy of the Monte Carlo model in accurately calculating radiation doses to patients.
