We need a plugin developed for Osirix pacs viewer. Very simple plugin you will only need to write about 20 lines of code. And I have most of the code necessary but don't have time to put it together and test it. Have a look at the Osirix viewer website for xml-rpc plugin developer guide and the sample xml-rpc plugin. The plug in is required to take in 2 parameters and open a study using Patient ID and Accession No. If you have basic knowledge in XCode and Objective C then this is for you!
