| Research Abstract |
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.
