Abstract

The present invention relates to a computer program product for analysis of a source medical image data set in a medical imaging system, being operable to: identify a user identity; identify at least one role linked to the user identity; load a source medical image data set; allow the user to review the loaded source medical image data set; allow the user to, based on role privileges, interactively perform processing operations on the loaded source medical image data set; create a processing protocol; allow the user to interactively specify at least one medical image data set characteristic to be associated with a processing protocol associater; allow the user to interactively restrict which user(s) to be associated with a user access right of the processing protocol by specifying which role(s) or which user identity/identities to be associated with the user access right; allow the user to interactively further restrict the role privileges; store the processing protocol in a central unit, and, if the user is associated with a user access right of a stored processing protocol, reload the stored processing protocol; allow the user to interactively choose the processing protocol for application, and apply the stored processing protocol.
