C.8.32.2.1 Lossy Image Compression and Lossy Image Compression Method​

If Lossy Image Compression (0028,2110) in any of the source images is "01", the value shall be "01" for the Parametric Map instance.​

- Standard -​

DICOM PS3.3 2020a - Information Object Definitions​

Page 1249​

The process of derivation of a Parametric Map itself is defined not to be lossy compression, even though it involves loss. If the Para-​ metric Map instance is encoded using a lossy compression Transfer Syntax, then the value shall be set to "01".​

Note​

To state the obvious, it is not advisable to lossy compress a Parametric Map SOP Instance, since that will alter the quantit-​ ative values that are the intent of the object.​

C.8.32.3 Parametric Map Functional Group Macros​

The following sections contain Functional Group Macros specific to the Parametric Map IOD.​

Note​

The Attribute descriptions in the Functional Group Macros are written as if they were applicable to a single frame (i.e., the​ Macro is part of the Per-frame Functional Groups Sequence). If an Attribute is applicable to all frames (i.e., the Macro is part​ of the Shared Functional Groups Sequence) the phrase "this frame" in the Attribute description shall be interpreted to mean​ "for all frames".​
