I am pleased to release our latest creation - Mayam (meaning Illusion). It's a Cross-platform DICOM viewer developed in Java using the dcm4che toolkit. We needed a viewer for use under Linux and couldn't find anything suitable that was full featured and ended up developing one on our own.

Download Mayam 0.5 Beta

Mayam is still work under progress. The current features are:

Viewer Features

  1. DICOM Listener for Q/R
  2. DICOM Send
  3. Local DB for storing study information
  4. Importing DICOM studies from local disk
  5. Parsing DicomDir from local disk or CD
  6. Query compressed studies without decompressing them
  7. Multiple Studies viewer using Layout,Tab view
  8. Export to JPEG (Study, Series, Instance level). Windowing can be applied to a single instance or series of instance while exporting
  9. Cine Loop & stack navigation
  10. Toggle for Text and Annotation Overlay
  11. Windowing Presets Settings (based on modality)
  12. Layout Settings (based on modality)
  13. AE Management
  14. DICOM Tags Viewer

Image Manipulation

  1. Windowing / Presets
  2. Invert, Flip & Rotate
  3. Zooming & Panning
  4. Annotation and Measurement Tools (Ruler, Rectangle and Elliptical)
Do try it out and give your feedback.

Suresh

PS. I'm posting this in the Oviyam forum for want of a better place. Damien - feel free to move it.

Cool!!!!!!!!!!!!! I can't wait to try it out!

I think this forum is fine for now... Who knows, if this becomes successful it might warrant it's own forum.

Do you want to put it into the dcm4che Sourceforge repository, or are you going to keep it on your SVN server?

We'll host the code in our SVN for now since we're still making a lot of changes. Once we're ready we'll move it to SourceForge.

Hi Suresh,

Looks interesting! I successfully imported a study but when I attempt to view a series it runs out of memory (I set my max heap to 2gb). The images are 512k and study is only 68mb total. I'm using Mac OSX 10.6. Also, it doesn't look like there's a log4j configuration file. 

log4j:WARN Please initialize the log4j system properly.

Damien - It seems that swing-layout-1.0.3.jar may be unavailable in the lib folder or it may be corrupted. Please check for its existence or download it again.

Ah yes, for some reason my zip file did not fully extract and I was missing the lib directory. It runs fine now....

It doesn't look like it displays non-image objects (key object selection documents), or applies presentation state. It also doesn't look like it supports multiframe objects. I tried to import a multiframe XA study and it just didn't work.

The exception in the KO study is as follows:

Key objects isn't supported yet. Multi-frame should work. Let me check again.

There were memory leaks in the application which caused "OutOfMemoryError" and also JAVA heap size parameters in run.bat were set incorrectly. It has been fixed now and the download link was replaced with the latest update.

Damien,

The XA study couldn't be imported in the viewer as the null value for study description was unhandled before, but now fixed.
Support for KO study and Presentation state are yet to be implemented.

Prakash.

I have a problem with the loading of the dicom images. My connection is OK with the DCM4CHEE, but when I retrieve all the dicom files, no image is loaded.
Direct images in local PC are loaded properly, but problems with the server PACS images.What shall I do? The connection between Mayam and DCM4CHEE is correct, but not seems to be
Thanks in advance
