Creating DICOM Multiframe files (MPEG to DICOM) using dcm4che 2

Hi There!

Long break, uh? Well, dear visitors, I have received a lot of emails asking about multiframe DICOM files. This time we will see an approach on how to build such files. A multiframe DICOM file usually has the meaning of a video file. You can open it in a DICOM viewer and then playback its frames.

To achieve such behavior we will need to know how to extract image frames from a MPEG-2 video file. FFMPEG program is a wonderful tool and complete, cross-platform solution to record, convert and stream audio and video. Also you can get Windows versions of FFMPEG here or here. Once your download is done unpack the FFMPEG file to you root directory and type the following command in your command prompt window:

DICOM Multiframe playback using dcm4che 2

Hello visitors,

First of all I'd like to thank you all for every email, tips, comments and mainly the valuable knowledge we have been sharing since I started this simple blog. This time I want to write a tutorial that takes a multiframe DICOM image and then playback it frame by frame. The final result is a Swing Java application where we can watch such file as it was a video file. If you feel it sounds nice so let's go!

If it's your first time here, please I strongly recommend that you read my DICOM to JPEG Conversion post so you can learn how to setup Eclipse and dcm4che toolkit. Then come back to this post and continue to this example tutorial. Let's start! Open your Eclipse IDE and choose File > New > Java Project. Name it DicomExamples. The next step is to create a new class, so right-click the src package and select New > Class. Enter DicomMultiframePlayer for class name and select the main method option. You'll get something like this:

CAD-PACS Integration

Hello,

We have published a promising study on the latest Computer Assisted Radiology and Surgery - 24th International Congress and Exhibition in Berlin, Germany. The study presents an open framework that uses dcm4che toolkit for integrating Computer-Aided Diagnosis (CAD) to Picture Archiving and Communication Systems (PACS). It's worth reading!

Brazilian team marries lung CAD with PACS Nearly all computer-aided detection (CAD) systems in clinical use today have a major shortcoming: the need to transfer image data to a separate workstation to run CAD software, with CAD data remaining separate from the PACS images radiologists read in their normal workflow. Researchers from São Paulo may have the answer. Click here to read more
