本文记录了平均身高和体重的估计，按年龄和性别，用于制定器官特异性剂量转换系数的外部辐射的历史队列约64,000例患者从加拿大荧光透视队列研究。1930年至1969年期间，在加拿大各地的住宅医疗设施中，患者在结核病治疗过程中反复接受荧光透视和胸部X线摄影检查。使用加拿大国家调查数据和广泛的文献综述，获得了感兴趣的时间段内加拿大白色人群的平均身高和体重，并估计了结核病患者和普通人群之间的平均体重差异。报告了选定年龄组（1岁、5岁、10岁和15岁的儿童和20岁以上的成人）和两种性别的加拿大结核病患者的平均身高和体重结果（不确定性）。使用估计的平均身高和体重的年龄和性别允许调整计算机化的幻影为体重为一个给定的年龄，从而增加了相关性的器官特异性剂量转换系数的队列，并提高了所得到的估计器官剂量的准确性。
This paper documents the estimation of mean heights and body masses, by age and sex, used in development of organ-specific dose conversion coefficients for external radiation for a historical cohort of about 64,000 patients from the Canadian Fluoroscopy Cohort Study. Patients were exposed to repeated fluoroscopy and chest radiography examinations in the course of treatment for tuberculosis in residential medical facilities throughout Canada between 1930 and 1969. Using Canadian national survey data and extensive literature review, mean heights and masses were obtained for the White population of Canada during the time period of interest, and the differences in mean body mass between tuberculosis patients and the general population were estimated. Results in terms of mean height and body mass of Canadian tuberculosis patients, with uncertainties, are reported for selected age groups (children of ages 1, 5, 10, and 15 y and adults age 20+) and for both sexes. Use of estimated average heights and body masses by age and sex permits the adjustment of computerized phantoms for body mass for a given age, thereby increasing the relevance of the organ-specific dose conversion coefficients for the cohort and improving the accuracy of the resulting estimated organ doses.
