Development of Computer code for Dose Management Using DICOM Radiation Dose Structured Report in X-ray Computed Tomography

Abstract

June 7, 2015, Japan Network for Research and Information on Medical Exposures（J-RIME）published Diagnostic Reference Levels（DRLs 2015）for the first time in Japan. To operate the DRL, it is necessary to collect a great deal of radiation dose information of own facilities efficiently. The purpose of this study was to construct a system for collecting dose information in CT examination using Radiation Dose Structured Report（RDSR）. As a result of displaying the contents of RDSR using the free software, it was confirmed that there are differences in the information in RDSR by equipment and manufacturers. In-house software of dose management could be designed by focusing on the enumerated value, it was possible to extract information of interest from RDSR. For facilities which cannot introduce a commercial system, development of software for collecting radiation dose information using RDSR contributes greatly to the operation of DRL.
