Supplement 187 Data Elements
Traditionally, the words used to describe how an image was acquired differ by the modality of the image, such as X-ray, CT scan, and MRI. This approach works well when image objects have very specific applications and when the domain from which the descriptive concepts are drawn is well understood and clearly defined.
In some cases, information about the acquisition that is relevant to the interpretation of the imaging may not be known to the modality. This is particularly the case in small animal preclinical research, where a myriad of factors that affect quantitative analysis need to be recorded, which would be overwhelming if required to be captured at the modality console user interface. Though it would be possible to add this information by post-processing of the acquired images,
Supplement 187 of the DICOM standard, published in 2015, defines use cases and templates for the storage of information related to the acquisition of small animal images during preclinical research.
If we want to collect data that describes how the data about the animal was acquired, we need standard terminology.

How a small animal image was acquired is important data that must be stored with the image. It is relevant to the interpretation of the image. While DICOM defines terminology applicable to other types of images, Supplement 187 defines terminology that is unique to small animal imaging.
