C. Pixel Representation

Pixel Representation (0028,0103) is specified to be Type 1 with the constraint that VR for all the pixel data will always be unsigned (US) and not signed (SS).

Enumerated Value: 0000H = unsigned integer

Note: The real-world values that are inherently signed (example: Flow Velocity, Tissue Velocity, Variance …) are represented as unsigned, unitless pixel values and may be mapped to signed real-world quantities via the Real World Value Mapping Macro.
