A.90 Confocal Microscopy Image IODs

The Confocal Microscopy Image IODs specify images that are acquired by means of a confocal microscope. The confocal microscopy may be performed in-vivo or ex-vivo in reflectance or fluorescence mode.

Confocal images may be simple (non-tiled) or tiled. Separate IODs have been defined for simple confocal microscopy images and tiled pyramidal images.

Simple confocal images may be encoded according the to the Confocal Microscopy Image IOD. A SOP Instance may contain one or more frames (multi-frame). A movie acquisition may be encoded as a multi-frame cine image.

A.90.1.1 Confocal Microscopy Image IOD Description

The Confocal Microscopy Image IOD specifies the Attributes of a simple (non-tiled) Confocal Microscopy Image.

A.90.1.2 Confocal Microscopy Image IOD Description Entity-Relationship Model

The Confocal Microscopy Image IOD uses the DICOM Composite Instance IOD Entity-Relationship Information Model defined in Section A.1.2, with only the Image IE below the Series IE.

A.90.1.3 Confocal Microscopy Image IOD Module Table

Table A.90.1.3-1 specifies the Modules of the Confocal Microscopy Image IOD.
