February Updates

I’ve recently added a number of version updates after a delay of a month.  I was working on changing the data structures I use within the CGI programs, so that I could easily pass around more information about each program.  I want to include with the internal object I pass around, such peripheral information as the name of the screen capture and thumbnail image files, and their sizes.  That’s done now, so I have caught up with some new versions, some of which are listed here.

 Vinci is a remarkable program from Stefan Vollmar and group at the Max Planck Institute for Neurological Research, in Cologne.  It is an extremely advanced analysis tool for neurological images, particularly PET.  I use this program daily and still am discovering functions and features I didn’t know were in the program.  That said, it would also be possible to use it simply for image viewing; it handles a wide range of input formats, and also conversions.  In the area of functional analysis, it has few peers.

Loni Debabler is another huge program from the extremely prolific LONI group at UCLA.  It takes an ambitious and interesting approach to image file conversion, providing a specialized programming environment for reading, manipulating and writing image files.  This is all controlled through a graphical programming environment, and processing schemas are stored as XML files.  Sample conversion programs are provided for the most usual image formats, or you can develop your own.  This is a program I’ve not yet used as much as I want to, its internals are complex but it’s tackling a difficult job.  I have to admit I’ve only used and modified the pre-programmed sample files.

PixelMed Java DICOM Toolkit is another advanced project, providing an extremely comprehensive implementation of DICOM tools.  It comes from David Clunie, a name familiar to everyone who has done any work at all in the field of DICOM programming.  This toolkit will provide more functionality than most people can utilize and comes from the foremost authority.  It is updated extremely frequently, such that version numbers are not used.  It’s difficult to convey on my site how frequently it is released, as almost all other projects release versions on a monthly to annual basis.  This software is revised almost weekly.  Perhaps I should make it a ‘sticky’ at the top of the ‘New Releases’ list.

Another very comprehensive library, in C++ this time, is Imebra from Paolo Brandoli, of PuntoExe software.  Here is another true open source program, where the free version is identical to the commercial, and source code is provided in both cases.  This project has recently gained its own website (imebra.com), and related projects based on the library are at the Puntoexe website.

DP Tools, from Denis Ducreux, is another active program.  It specializes in the field of functional MRI and MR Diffusion.  I know nothing about this field but have seen an increasing amount of excellent software emerging.  It’s written in Delphi, in common with some of Chris Rorden’s very widely used imaging software.  I am also profoundly ignorant of Delphi, I seem to be exposing my weaknesses here.

ITK-SNAP is another specialized neuro program, this time for segmenting brain images.  It incorporates elements of the NLM Insight Segmentation and Registration Toolkit, hence the name.  Formerly developed at UNC-Chapel Hill and now at Penn, this project provides automatic and manual brain segmentation methods.  It’s cross-platform.

TomoVision is a little program that displays DICOM images and doesn’t do much else.  And, the free version is limited to 5 images.

MedImaView has a new version out.  It’s another small DICOM viewer, when I tried it just now I could only open multiple files via drag and drop, and when I dropped a 192-frame MRI sequence I got: 192 windows.  Hmmm.
