C. Pixel Value Transformation Macro

Table C.7.6.16-10 specifies the attributes of the Pixel Value Transformation Functional Group macro.

Note: This Macro is equivalent with the Modality LUT transformation in non Multi-frame IODs.


Attribute Name Tag Type Attribute Description
Pixel Value Transformation Sequence (0028,9145) 1 Contains the attributes involved in the transformation of stored pixel values. Only a single Item shall be included in this sequence.
>Rescale Intercept (0028,1052) 1 The value b in relationship between stored values (SV) and the output units. Output units = m*SV + b.
>Rescale Slope (0028,1053) 1 m in the equation specified by Rescale Intercept (0028,1052).
>Rescale Type (0028,1054) 1 Specifies the output units of Rescale Slope (0028,1053) and Rescale Intercept (0028,1052). See C. for further explanation. Enumerated Value: US = Unspecified if Modality (0008,0060) equals MR or PT.

Note: Window Center (0028,1050) and Window Width (0028,1051) are applied after Rescale Slope (0028,1053) and Rescale Intercept (0028,1054) have been applied to Stored Pixel Values, see C.
