C.8.21.2 X-Ray 3D Contributing Image Sources Modules

This section describes the X-Ray 3D Image Contributing Sources Modules.

Notes: 1.These modules supply general information of the sources without the need to have access to all the contributing SOP Instances or when these SOP Instances do not exist.

2. These modules do not contain specific information of the X-Ray acquisition itself. For this purpose the X-Ray 3D Acquisition Modules may be used.

C.8.21.2.1 X-Ray 3D Angiographic Image Contributing Sources Module

This section describes the X-Ray 3D Angiographic Image Contributing Sources Module. The attributes in this Module specify the overall characteristics of one or more sources that were used to create a X-Ray 3D Angiographic Image SOP Class instance. Table C.8.21.2.1-1 contains the relevant IOD Attributes that describe X-Ray 3D Angiographic Image Contributing Sources.

C.8.21.2.3 Breast Tomosynthesis Contributing Sources Module

This section describes the Breast Tomosynthesis Contributing Sources Module. The attributes in this Module specify the overall characteristics of one or more source images that were used to create a Breast Tomosynthesis Image SOP Class instance. Table C.8.21.2.3-1 contains the IOD Attributes that describe Breast Tomosynthesis Contributing Sources.

Note: The intention of this module is to supply acquisition information without the need to have access to all the source projection images.
