### Note

1. The Attributes specified in the General Equipment Module (see Table C.7-8) describe the equipment that created the image being captured. The Attributes of the SC Equipment Module define the equipment that captured the image. The following table illustrates typical scenarios for different conversion types:

   Conversion Type (0008,0064) | General Equipment | Secondary Capture Equipment
   --- | --- | ---
   Digitized Video (DV) | The equipment generating the video signal. | The equipment digitizing the video signal.
   Digital Interface (DI) | The equipment on the sending side of the digital interface. | The equipment on the receiving side of the digital interface.
   Digitized Film (DF) | The equipment that created the film. | The equipment digitizing the film.
   Workstation (WSD) | Application dependent, but often the equipment that placed the image on the workstation screen, or created the modified image. | The equipment that captured the image from the screen, or placed the modified image into a DICOM SOP Instance.
   Scanned Document (SD) | The equipment that created the document. | The equipment digitizing the document.
   Scanned Image (SI) | The equipment that created the image that was digitized. | The equipment digitizing the image.
   Drawing (DRW) | The equipment that created the drawing. | The equipment digitizing (or rasterizing) the drawing.
   Synthetic Image (SYN) | The equipment creating the original images from which the synthetic image was derived. | The equipment creating the synthetic image.

2. Modality (0008,0060) specified in the General Series Module (see Table C.7-5a) has been specialized by this Module and is defined as a Type 3 Attribute.
