Dose index information obtained from imaging equipment is being increasingly used for improving QA and QC program in a facility as well as to satisfy regulatory requirements. Tools for gathering this information include on-board features as well as standalone solutions. Implementations can vary in the details of how the indices are collected, stored, analyzed, and presented, as well as details of calculated or derived parameters such as size-specific dose estimates. Medical physicists need to be aware of the methods, models, assumptions, and data being used in order to safely and properly use the results. Towards this end, AAPM Task Group 257 “Medical Physics Practice Guidelines on Selection of a Radiation Dose Index Monitoring System” has proposed the following recommendations:
•Informatics considerations
➢Potential interaction with other clinical imaging information systems
➢Communications with standards and protocols
➢Vendor dependence/independence
➢HIPAA and HITECH compliance
•Common requirements for all modalities
➢Tracking of radiation dose indices
➢Outlier notification
➢User management
➢Dose analysis tools with user interface elements
•Modality-specific dose indices
➢CT
•CTDIvol, CTDI phantom, DLP of each series
•Size-specific dose estimate
➢Fluoroscopy
•Air kerma, kerma area product
•Exposure incidence map
➢Planar x-ray (CR/DR, mammography)
•Air kerma, kerma area product, average glandular dose (mammography), exposure index and deviation index
➢Nuclear Medicine (including PET)
•Radionuclide, pharmaceutical, pre/post administration activity
Over two sessions, Partners in Solutions will present representatives from seven commercial vendors who will respond to these recommendations and present details of their radiation dose index monitoring systems.
