Many techniques and research models on calculating and reducing the nuclear radiation dose on pediatric nuclear medicine procedure have been developed and reported in recent years. However, most those models either utilized simple shapes to present the organs or used more realistic models to estimate the nuclear dose applied on pediatric patients. The former are too simple to provide accurate estimation results, and the latter are too complicated to intensively involve complex calculations. In this study, a simple but practical model is developed to enable physicians to easily and quickly calculate and select the average optimal effective nuclear dose and critical organs for the given age and weight of the pediatric patients. This model is built based on one research result reported by Frederic Fahey et al., and it can be easily implemented in most common pediatric nuclear medicine procedures. This is the first research of using fuzzy inference system (FIS) to calculate the optimal effective dose applied in the nuclear medicine for pediatric patients.
