A web-based dose computation system, WAZA-ARI was developed to calculate organ doses to a patient in a computed tomography examination. The organ dose were derived by the Monte Carlo simulation using the Particle and Heavy Ion Transport code system, combined with Japanese voxel phantom. Real time calculation can be obtained using the WAZA-ARI over the Internet. Users choose scanning options and input parameters via a web browser. Organ doses are finally computed based on the radiographic exposure (mAs) and the pitch factor. The dose can be also estimated for Automatic Exposure Control (AEC) changing attenuation along the patient's length.

开发了一个基于网络的剂量计算系统WAZA-ARI，用于计算计算机断层扫描检查中患者的器官剂量。使用粒子和重离子输运程序系统，结合日本体素体模，通过蒙特卡罗模拟计算器官剂量。真实的时间计算可以通过互联网使用WAZA-ARI获得。用户通过Web浏览器选择扫描选项并输入参数。器官剂量最终根据射线照相曝光（mAs）和螺距因子计算。还可以针对自动曝光控制（AEC）沿患者长度沿着改变衰减来估计剂量。
