AAAAA.2.2 Presentation and Review

Display Systems are likely to encounter Photoacoustic data sets that have been acquired and organized in a variety of ways. Data sets may include images from one or more optical wavelengths, possibly processed with several different algorithms to represent one or more imaged properties. A common Dimension Organization UID (0020,9164) establishes a relationship between the Photoacoustic images based on temporal position, spatial position and a unique set of imaged properties and excitation wavelengths (see Section C.8.34.1.2 “Photoacoustic Dimension Organization Type” in PS3.3).

The logic for visualization of Photoacoustic images on an Image Display workstation is similar to the logic for visualizing 3D Ultrasound Volume data. The workstation should be capable of displaying multiple 3D image objects simultaneously. To allow the most effective use of the Photoacoustic studies, the workstation should be capable of using Hanging Protocols and Advanced Blending Presentation State objects (Section C.11.33 “Advanced Blending Presentation State Module” in PS3.3).

The Image Display workstation is not expected to be capable of creating algorithmic combinations of Photoacoustic images; the processing for a Photoacoustic image is generally performed by the modality (see Reconstruction Algorithm Sequence (0018,993D) ).

AAAAA.2.2.1 Fusion Visualization With Complementary Imaging Modalities

In the fusion use case, an Image Display workstation is used for synchronized display or overlay (fusion) of multiple Photoacoustic images and/or images from another complementary acquisition modality.

The process for such fusion is not described in further detail, however the Advanced Blending Presentation State object (Section C.11.33 “Advanced Blending Presentation State Module” in PS3.3) is recommended with the complementary modality utilizing temporal and volumetric dimensions as described in the Multi-frame Dimension Indices specified in Section C.8.34.1.2 “Photoacoustic Dimension Organization Type” in PS3.3.
