Definition
A string of 32-bit IEEE 754:1985 floating point words. OF is a VR that requires byte swapping within each 32-bit word when changing byte ordering.

Working with OF in integration code
VR-aware transformations are where most DICOM integration bugs hide — truncating a PN's 5-component structure, misaligning OB padding, or dropping leading zeros on IS. Saga IT builds production DICOM pipelines that respect VR semantics across Mirth Connect transformers, DIMSE gateways, and cloud DICOM services.
