Outline of Final Research Achievements

Patient dose management using DICOM header files is becoming common. However, some problems have become apparent, because dose information may be stored in ‘private’ fields in many instances and dose units vary among manufacturers. Furthermore, it is not uncommon to find that a DICOM header file has no dose information. Therefore, it is imperative to standardize DICOM header dose information. Some recent reports have described the usefulness of patient dose management using DICOM SR. However, the use of DICOM SRs in X-ray systems is currently very limited. We have developed a dose-management system using an RIS and an MPPS interface. Both radiographic information from the X-ray system and dosimetric information from the DAP meter can be sent to the RIS using the MPPS interface.
To improve dose management, it is necessary to use a combination of DICOM and an RIS system.
