Abstract

The aim of the study was to determine the effect of irradiation time, the percentage of the maximum dose, the distribution of doses at the center point, and the wedge factor on wedge filter variations. The research method uses a wedge filter to measure irradiation time, maximum dose percentage, dose distribution at the center point, and the wedge factor. Wedge value factor without wedge, wedge 15 , wedge 30, wedge 45and wedge 60of 1.000, 1.0059, 1.0102, 1.0137, and 1.0092 respectively. The results of the maximum dose percentage values without wedge, wedge 15 , wedge 30 , wedge 45and wedge 60were 106.76%, 106.80%, 106.79%, 106.85%, and 106.81%, respectively. Conclusion is the value of the wedge factor does not comply with the ICRU standard but the percentage of the maximum dose is in accordance with the International Commisson on Radiation Units (ICRU) standard, there is a wedge effect factor, and irradiation time on the variation of the wedge filter, but there is no effect of the maximum dose percentage and distribution at the center point on the variation of the wedge filter.

亚装置放疗中癌性乳腺癌患者楔滤光器楔因子的变化

本研究的目的是确定辐照时间、最大剂量的百分比、剂量在中心点的分布以及楔形因子对楔形滤光器变化的影响。研究方法采用楔形滤波器测量辐照时间、最大剂量百分比、中心点剂量分布和楔形因子。楔形值因子无楔形、楔形15、楔形30、楔形45和楔形60分别为1.000、1.0059、1.0102、1.0137和1.0092。无楔形、楔形15、楔形30、楔形45和楔形60的最大剂量百分比值分别为106.76%、106.80%、106.79%、106.85%和106.81%。结论:楔形因子值不符合ICRU标准，但最大剂量百分比符合国际辐射单位委员会(ICRU)标准，存在楔形效应因子和照射时间对楔形滤光器变化的影响，但最大剂量百分比和中心点分布对楔形滤光器变化没有影响。

期刊介绍： The SEAMEO* Regional Tropical Medicine and Public Health Project was established in 1967 to help improve the health and standard of living of the peoples of Southeast Asia by pooling manpower resources of the participating SEAMEO member countries in a cooperative endeavor to develop and upgrade the research and training capabilities of the existing facilities in these countries. By promoting effective regional cooperation among the participating national centers, it is hoped to minimize waste in duplication of programs and activities. In 1992 the Project was renamed the SEAMEO Regional Tropical Medicine and Public Health Network.
