Whether the media is a photo (still image), an audio recording, or a video recording.

Details of the type of the media - usually, how it was acquired (what type of device). If images sourced from a DICOM system, are wrapped in a Media resource, then this is the modality.

Identifiers associated with the image - these may include identifiers for the image itself, identifiers for the context of its collection (e.g. series ids) and context ids such as accession numbers or other workflow identifiers.

The identifier label and use can be used to determine what kind of identifier it is.

Who/What this Media is a record of.

The person who administered the collection of the image.

The name of the imaging view e.g. Lateral or Antero-posterior (AP).

The name of the device / manufacturer of the device that was used to make the recording.

Height of the image in pixels (photo/video).

Width of the image in pixels (photo/video).

The number of frames in a photo. This is used with a multi-page fax, or an imaging acquisition context that takes multiple slices in a single image, or an animated gif. If there is more than one frame, this SHALL have a value in order to alert interface software that a multi-frame capable rendering widget is required.

The duration of the recording in seconds - for audio and video.

The actual content of the media - inline or by direct reference to the media source file.

Recommended content types: image/jpeg, image/png, image/tiff, video/mpeg, audio/mp4, application/dicom. Application/dicom can contain the transfer syntax as a parameter. For an media that covers a period of time (video/sound), the content.creationTime is the end time. Creation time is used for tracking, organizing versions and searching.
