Video support with FFmpeg
DicomObjects Version 8 we have added support for video handling with pluggable custom codec. We have provided primary support for FFmpeg codec which is replaceable and optional. FFmpeg is a well established multimedia software that handles all sorts of popular video formats. We have implemented it in DicomObjects to allow importing of supported video formats, embedding them into DICOM and exporting them using the appropriate transfer syntax and vice versa.
Web Access to DICOM Persistent Objects (WADO)
WADO is a protocol (defined in DICOM Part 18) for retrieving DICOM Composite Instances using the http or https protocols. It is simple to write a WADO server using DicomObjects - see the Example on the web
Web Service for Activation
Though not recommended for general use, the Web Service for activation is publicly accessible.
The Well-Known UIDs are Static Instance UID mostly used in normalised operations. The following is a list of all UIDs in DICOM
Windowing and Scrolling Speed
The default behaviour of DicomObjects is to use smoothing for minimised images, where ActualZoom is < 1 (ensuring that all image pixels contribute to the display), but not to use it for images scaled up (in order to minimise regulatory concerns about “enhanced” images and possible artefacts). See MagnificationMode & MinificationMode for more details.
Whilst this is a preferred settings for most cases, it does have a performance penalty, and if left enabled during fast update operations the display update appears to be slow or “jerky”.
XDS for Imaging (XDS-I) is an extension to the IHE XDS protocol explicitly for imaging, which stores a DICOM Key Image Note (aka Key Object Selection Document) as the stored object in the Document Repository which in turn lines to the images in the “Image Source” (normally the original PACS, or perhaps a regional equivalent).
The images can be retrieved using either C-MOVE or more commonly using WADO
