In diagnostic radiology, entrance surface air kerma (ESAK) is one of the patient radiation dose quantities, and the effective dose is used as an estimator of possible risk for radiation exposure level. Calculation of the ESAK and effective dose requires both X-ray machine parameters and patient exposure parameters. Due to the high performance of smartphones and the increase in mobile applications, this study aimed to develop a mobile application to estimate the ESAK and effective dose in general radiography. The ESAK calculator was then developed using Android studio software, which is a standalone application operating on Android operating system version 5.0 or higher. X-ray machine parameters are initially required for calculating X-ray output. For the ESAK and effective dose calculation, exposure parameters for each examination are needed. The results showed that the average score of satisfaction was 4.64±0.13, which was very satisfactory. In conclusion, the ESAK calculator could be used for estimating ESAK and effective dose for individual radiographic examination.
在诊断放射学中，体表空气比释动能（ESAK）是患者辐射剂量的量之一，有效剂量用作辐射暴露水平潜在风险的估计值。ESAK和有效剂量的计算需要X射线机参数和患者照射参数。由于智能手机的高性能以及移动应用的增加，本研究旨在开发一种移动应用程序，以估计普通放射摄影中的ESAK和有效剂量。然后使用安卓工作室软件开发了ESAK计算器，这是一个独立应用程序，运行在安卓操作系统5.0或更高版本上。计算X射线输出最初需要X射线机参数。对于ESAK和有效剂量的计算，需要每次检查的照射参数。结果表明，满意度平均得分为4.64±0.13，非常令人满意。总之，ESAK计算器可用于估计个体放射检查的ESAK和有效剂量。
