Abstract
Objective To explore a rapid method of calculating an percentage depth dose for irregular beam fields. Methods Worked out the percentage depth dose of irregular fields by means of A, B, C, D.Then compared the prescription doses and those measured. Results The average error of the method A is 3.67％,the average error of the method B is 0.47％.For the method C.the average error of rules block radiation beam fields is 0.24％, the average error of irregular block radiation beam fields is 0.69％.The average error of the method D is 0.28％. Conclusion In calculation of the percentage depth dose of iregular beam fields.the average error of the method B is 0.47％,it is less than ±l％.The method B is convenient for standardized operations and meets the accuracy demand.关键词
