DICOM DirectShow filters need to be registered before they can be used. They do not need to be copied into the system directory, but do need the LEADTOOLS Medical DLLs to work properly.
|DICOM File Reader||LTDicRd2.DLL
|ILTDicRd2.h||Use the DICOM File Reader to stream the video data in any DICOM file. In addition, it makes it possible for any DirectShow-based media player to play video data in a DICOM file. The filter offers the ability to control the stream speed by changing the frame time. In addition to the basic stream and speed control functionality, the user can insert a user-defined external DICOM dataset and get access to the initialized dataset for use with other processes.||DICOM File Reader Help|
|DICOM File Writer||LTDicWrt2.DLLDSKernel2.DLL||ILTDicWrt2.h||Use the DICOM File Writer to add video data to a DICOM dataset. The filter has a built-in JPEG and JPEG2000 compressor so it can create JPEG or JPEG2000-compressed DICOM files. It can also be used in conjunction with the LEAD MPEG2 Multiplexer, LEAD MPEG2 Encoder or another MPEG-2 Encoder to create DICOM files with MPEG-2 compression (SD or HD). This filter can be used either as stand-alone or through the LEADTOOLS Medical toolkit. Even when used as stand-alone, the filter still requires redistributables from the Medical Imaging toolkit.||DICOM File Writer Help|
Registering the DICOM Reader Filter makes it possible to use any DirectShow-enabled player to automatically play DICOM files. The LEADTOOLS Multimedia toolkit can play DICOM files just like any other video file.
Access the DICOM Reader property page to change the playback rate. The property page can be brought up by the LEADTOOLS Multimedia toolkit using IltmmPlay::HasDialog.
The filter has a built-in JPEG2000 decompressor so it can read JPEG2000-compressed DICOM files. The filter needs the raster LFCMP filter in order to play JPEG-compressed DICOM files.
Some DICOM files are in 16-bit grayscale format. Such files can only be played if the LEAD Video RGB Converter Filter (LMVRGBXF.DLL) or the LEAD Color Space Converter (LMVYUVxf.DLL) is installed (but 8-bit or 24-bit DICOM files can be played without having these conversion filters installed).
Some DICOM files contain:
For more information about the LEAD DICOM Reader Properties page, refer to the ILTDicRd Interface.
DICOM files can contain MPEG2 Transport streams with H264 Video plus AC3 audio compression. To create these, you will need the LEAD MPEG2 Transport Multiplexer, LEAD H264 Encoder, and LEAD AC3 Encoder.
Some of the key features for this filter include:
Accepts the following Stream data subtypes:
DICOM DirectShow filters require the following raster DLLs in order to work properly:
