New OHIF viewer plugin release candidate

[Simon Doran]

Hi Everyone,

  This is just a quick message to let you all know that the first release candidate for the forthcoming 3.2.0 release of the OHIF viewer plugin is now available for community evaluation and testing here. Please do not install this on production instances of XNAT.

  The main focus of the new version is to provide an image overlay mode to allow display of, for example, PET-CT.  The RC1 candidate has this enabled in MPR view, but we hope that by the time we get to the full release we will have this in the normal 2-D slice view as well, to allow ROIs to be drawn.

 We aim to spend about a fortnight putting in place some final tweaks, so please would as many of you as possible have a go at downloading successive release candidates as they appear and give us appropriate feedback on our issues page. We don't have any documentation yet, so if things are unclear, please just get in touch and we will do our best to help.

  Many thanks in advance for helping to make the viewer better!

  Best wishes,

Simon
