Introduction to DicomObjects COM version
DicomObjects consists of an inter-related, but independent, set of “Objects” that enable developers quickly and easily to add DICOM functionality to their products without needing to understand or program the intricacies of the DICOM standard.
This help file provides full reference
Almost any aspect of DICOM image/data manipulation can be performed using DicomObjects, including:
- Image display and manipulation
- Network transmission of images and associated data, including worklists
- Printing to DICOM and windows printers
- Normalised operations including storage commitment
- Image creation from scratch and import/export to/from non-DICOM formats
The main Components of the DicomObjects Collection are:
DicomViewer Control
An ActiveX control that may be embedded into any suitable control container such as Visual Basic, standard development environments such as C++ (Microsoft or Borland), Delphi, Microsoft Access, and can even be used in Internet Explorer. I t has extensive display capabilities for DICOM images, whether read from files, received over the network, or from numerous other sources, and these include a wide range of annotations, and full DICOM greyscale presentation state support.
It also provides service class provider (SCP) functionality for verification, storage, query/retrieve and normalised operations.
DicomServer Object
An automation object without a user interface that provides storage, query/retrieve and normalised facilities as a service class provider (SCP).
DicomQuery Object
A non-visual automation object that handles the query/retrieve parts of the DICOM standard as a service class user (SCU).
DicomPrint Object
An automation object that simplifies DICOM printing as a service class user (SCU).
DicomGlobal Object
Used for certain global operations such as over-riding registry values
DicomConnection Object
A DicomConnection Object represents an association, and may either be created automatically in response to an incoming query request, or explicitly by the client program. Methods of this object are used to send data, images, and verification requests, and this object is central to DicomObject’s asynchronous operation capabilities. As of version 4.1, there is also a DicomConnections collection.
Other dependent automation objects and collections are created and used by the above, and some may also be created directly. They are:
| Object Description | Single Item | Collection |
|---|---|---|
| SOP instance, containing an image | DicomImage | DicomImages |
| Generic SOP instance, used for results of DICOM queries or as a sub-element of a Sequence | DicomDataSet | DicomDataSets |
| Attribute (Data Element) of either of the above | DicomAttribute | DicomAttributes |
| DICOM Presentation context | DicomContext | DicomContexts |
| Image Annotation | DicomLabel | DicomLabels |
