Capturing patient doses from fluoroscopically based diagnostic and interventional systems.
Modern fluoroscopic systems can automatically document both dosimetric and technical procedural values. Certain useful dose metrics are reviewed in this paper. Fluoroscopic time alone is an insufficient tool for the management of high dose interventional procedures. The DICOM-DOSE project (a joint IEC-DICOM initiative) will enable collection of complete dose data from all x-ray imaging modalities irrespective of storage of the associated images. Data should be collected for every procedure where there is any possibility of a deterministic radiation injury. Appropriately sampled data may be sufficient for QA purposes and for estimating stochastic risk.
