It includes:

• JNI wrappers for most of the Imebra classes
• DicomView class to display Dicom images, with support for zoom and pan
• documentation

The open source license has been changed from BSD to GPLv2. A commercial license is available in order to fund further development of the library.

Change log

• Changed license to GPLv2/commercial
• Fixes #89 (Static objects don’t get initialized when Imebra is built as a library)
• Added support for ICU library
• Removed unused parameter from dicomCodec::readPixel()
• Compatible with clang 3.0
• Added memory::memory(imbxUint32 size) to allocate memory in the constructor
• Added method that finds the optimal VOI for the VOILUT transform
• Validate the area that must be processed by the transform
• Corrected mismatching new/delete in streamController
• Added handling of ARGB and RGBA bitmap modes to drawBitmap
• Splitted charsetConversion into several classes

Imebra SDK for Android is based on the C++ library “Imebra SDK for C++” plus some Java wrappers that call the native library via JNI.

Because “Imebra SDK for Android” is basically written in C++, it is extremely fast when decoding the Dicom stream (oh, by the way, it accepts compressed and uncompressed streams).

“Imebra SDK for Android” loads only the parts of the Dicom file it needs, so it can easily open a hundreds of Mb file containing several images and decompress the images when they are needed; Competitor SDKs die when exposed to those files.

Imebra for Android

The possibility of reading compressed DICOM files is coming to Android.

Imebra SDK for Android has reached an alpha status and started spitting out valid data on Android devices.

Imebra SDK for Android uses the native library Imebra SDK for C++ plus some JNI wrappers that allow to use the library from Java. Imebra SDK for Android is composed by a SO module containing the native code and a JAR containing the Java interface.

In order to fund further development of Imebra SDK for C++, Imebra SDK for Android will be available only to paying customers, which will receive also the full source code of the JNI wrappers (non redistributable). A demo version of Imebra SDK for Android will be available (binaries only, with limitations).

dicom2jpeg is an application distributed with Imebra (look in the examples folder), while ffmpeg is an open source application downloadable from here or here (windows).

dicom2jpeg can convert a dicom file to one or more jpeg images, while FFMpeg is able to produce a movie (mpeg, flash and other) from a series of images. Combining them together allows us to convert a dicom file to a movie.

The version 0.0.45 of Imebra introduced a new feature to dicom2jpeg that makes it able to call directly ffmpeg with the automatic setting of few key options (like the frame rate).

In order to conver a dicom file to a flash movie, open a command line terminal and type:

dicom2jpeg pathToDicomFile pathToOutputImage -ffmpeg pathToFfmpeg pathToMovieFile

where:

• pathToDicomFile = path to the dicom file that has to be converted to a movie
• pathToOutputImage = path to the output jpeg images: e.g.: c:\temp\image.jpg will generate the series of images c:\temp\image0.jpg, c:\temp\image1.jpg, c:\temp\image2.jpg,…
  The folder where the images will be create has to exist
• pathToFfmpeg =path to the ffmpeg application. Most of the time the string ffmpeg is enough
• pathToMovieFile = path to the movie file that generated by ffmpeg, e.g.: c:\movie.flv a flash file or c:\movie.wmv to generate a windows media video file

After -ffmpeg you can specify all the options accepted by ffmpeg, using the same syntax specified in the ffmpeg manual.

Some parameters needed by ffmpeg, like the frame rate and the input images are automatically added by dicom2jpeg.

Using dicom2jpeg on a web server

Few precautions have to be taken to use dicom2jpeg on a web server.

The software may be called from several threads at the same time; it is important that when dicom2jpeg is called a fresh folder for the images and the final movie is generated, possibly using a session identifier in the folder name.

After the movie has been generated, the images or all the folder should be deleted by the calling application.

Converting a Dicom file to a video file…the commercial way

Dicom Media Bridge is a Directshow codec based on Imebra that allows Windows media applications to play Dicom files directly.

After installing Dicom Media Bridge you can play Dicom files using Windows Media Player or you can convert them to video files using Windows Media Encoder or other similar products.
