In case of radiation having a HVL between 0.07mm Cu to 2.5mm Cu corresponding to a X-ray tube voltage of about 60 to 220kV, the maximun error of. the energy response was below 1.5%.
体积为0.5cm~3，以纯石墨为壁体的电离室，在X射线管电压为60～220kV、半价层为0.07mmCu和2.5mmCu时，其能量响应的最大误差不超过1.5％，而对~(137)Cs和~(60)Co γ射线的校正因子(附加3.75mm有机玻璃平衡帽)也处在上述范围内；体积为2cm~3，分别以酚醛塑料、纯石墨、聚四氟乙烯为壁体的电离室，在上述能量范围内，其能量响应最大误差为3～5％；体积为200cm~3，以酚醛塑料为壁体的电离室，其最大校正因子为5％。
On measuring half value layer, HVL, and entrance dose by using different type of target/filter combination, we compared three modes of target/filter (Mo/Mo, M/Rh, W/Rh) combinations, and evaluated the differences and benefits. Finally, we proved the proper parameter settings (kV、Target/Filter) can reduce large amount of breast dose.
