Current Version: Oviyam 0.9 Final Release (Rev13641) - 29 June 2010

  • OV-23 : Adding measurement tools - So far "Line measurement" tool has been added**
  • OV-74 : Window Level params should be put into user session rather than servlet context
  • OV-80 : Support to run multiple instance of Oviyam on a single server with separate configurations
  • OV-81 : Higher "rows" size images are retrieved for thumbnail pane, while main image is loaded with lesser "rows" size

Great work by Jeffrey Miller in adding line measurement to OV-23. This code will be the foundation for additional measurements and annotations in future.

Previous version (Oviyam 0.8 R12) - 02 May 2009

Bug Fixes

  • OV-48 - Additional query parameters for launching Oviyam from other programs. Specially using the Accession number.
  • OV-49 - Issues loading Oviyam with study context.
  • OV-50 - Javascript error when changing background color before selecting a study.
  • OV-52 - WL/WW and Move operation shouldn't be triggered together.

Previous version (Oviyam 0.8 R1) - 26 March 2009

New & improved in this release

  • WL/WW values used to generate the JPEG image are displayed on the screen.
  • WL/WW can be changed with mouse operation like Xero.
  • WL/WW Presets for Chest /Abdomen/Pelvis, Lung, Brain, Bone and Head/Neck (OV-24).
  • WL/WW values can be manually entered.

Bug Fixes

  • Studies containing empty "Referring Physician Name" were not shown in the patient's list.
  • Multi - Modality studies were not listed and shown as single modality in the patient list.
  • Patient Information was not displayed in the viewer, when direct URL is used.
  • Multi-frame XA studies view was broken in the 0.7 release.
  • Multi-frame objects are no longer expanded as a instance.
  • Studies with Special Characters in the patient's name could not be opened or viewed.
  • Series with duplicate series numbers could not be opened.

Notes

As is obvious, the focus of this release has been Window Level & Window Width manipulations since this was a frequently asked for feature.

For performance & bandwidth reasons we had to make the following compromises.

  • Oviyam retrieves a new image only on mouse button up, based on the delta of mouse movement, not on mouse move as in Xero. In plain words, Oviyam fetches a new JPEG image with the changed WL/WW only after the mouse button is released, based on the distance the mouse button has been clicked and moved. Xero continuously fetches new JPEG images as the mouse is clicked and moved over the image.
  • DICOM images larger than 1024 pixels in width are proportionately scaled down to 1024 pixel width.

At present we're using the standard WADO service of dcm4chee. Bill has implemented a faster and more optimized version called WADO2 in his Xero project which we would like to move to in future.

Thanks to Justin who contributed code from one of his projects for WL/WW presets.

Previous version (Oviyam 0.6) - 26 December 2007

This release has taken longer than expected but I think you'll agree with me that the delay has been worth it. So as a Boxing Day special here's what's new:

We finally have a name! After going through several suggestions we now present Oviyam (IPA: ovɪyum - Tamil for art. In Tamil: ஓவியம்), Web DICOM browser. I now know the difficulties faced by parents in naming their kids. You have my sympathies (smile)

Under the hood

  • Now licensed under MPL 1.1/GPL 2.0/LGPL 2.1 to bring it in compliance with the dcm4che project
  • Now using Ant to create builds

WYSIWYG

  • Ground up rewrite using CSS & AJAX
  • W3C compliance
  • Single window interface - earlier versions would sometimes spawn a new window
  • Configuration option for Host name, port, AETitle & WADO port (WADO port issue pointed out by Phil)
  • Patient list slides out of view when a study or series is selected (Idea suggested by Ron Sweeney)
  • Toggle Series pane in & out of view
  • Keyboard shortcuts to navigate & move back and forth between images in a series
  • Display of non-square images with proportional scaling (Issue pointed out by Jan)
  • Pan & Zoom
  • Launch Oviyam with a study/series context (Peter & Damien had asked for this.) We're using the syntax defined by Bill for Xero.

Known Bugs

  • The query results present different studies for the same patient as separate lines
  • Sliders do not work properly in Safari
  • Date picker is MIA in the query screen
  • Not tested under Safari 2.0, Internet Explorer or Opera - results are unpredictable (Firefox & Safari 3.0 are the preferred browsers for now)

Keyboard shortcuts:

  • P - toggle patient list
  • S - toggle series preview
  • G - Grid view
  • M - Mosaic view
  • L - Play images in a Loop
  • Up / Left arrow / - (minus) - move to next image in series
  • Down / Right arrow / + (plus) - move to next image in series
