Abstract
The ACR-NEMA Standard provides mechanisms by which a considerable amount of non-image information can be transmitted along with an image. Much of this information is similar to data currently managed by radiology information systems. However, the Standard does not provide methods by which the accuracy and consistency of these data can be maintained at a level that makes them usable for such important functions as billing or statistical analysis. A strategy by which extended versions of existing radiology information systems can be implemented with an ACR-NEMA-compatible PACS to provide data accuracy and consistency is discussed. The Standard also provides a mechanism to transmit the location and orientation of planar cross-sectional images. This will simplify obtaining measurements such as those necessary for stereotoxic techniques in CT, MRI or PET. However, the mechanism is not adequate to deal with the geometrical complexities of projection images. This creates an awkward situation for localizer images in CT and MRI. Extending the Standard to deal with projection images would not only remove this defect but also encourage the development of new quantitative applications in digital radiography.
